"'While Scrum has its potential cons and challenges, many organizations have successfully embraced and implemented this project management framework to great effect. The cons mentioned above can be mitigated or overcome with proper training, support, and a commitment to continuous improvement. It is also important to note that not all cons may be applicable to every organization or project.\\n\\nFor example, while Scrum may be complex initially, with proper training and guidance, teams can quickly grasp the concepts and practices. The lack of predictability can be mitigated by implementing techniques such as velocity tracking and release planning. The limited documentation can be addressed by maintaining a balance between lightweight documentation and clear communication among team members. The dependency on team collaboration can be improved through effective communication channels and regular team-building activities.\\n\\nScrum can be scaled and adapted to larger projects by using frameworks like Scrum of Scrums or LeSS (Large Scale Scrum). Concerns about speed versus quality can be addressed by incorporating quality assurance practices, such as continuous integration and automated testing, into the Scrum process. Scope creep can be managed by having a well-defined and prioritized product backlog, and a strong product owner can be developed through training and mentorship.\\n\\nResistance to change can be overcome by providing proper education and communication to stakeholders and involving them in the decision-making process. Ultimately, the cons of Scrum can be seen as opportunities for growth and improvement, and with the right mindset and support, they can be effectively managed.\\n\\nIn conclusion, while Scrum may have its challenges and potential cons, the benefits and advantages it offers in terms of collaboration, flexibility, adaptability, transparency, and customer satisfaction make it a widely adopted and successful project management framework. With proper implementation and continuous improvement, organizations can leverage Scrum to drive innovation, efficiency, and project success.'"

# Primitives
|
||||
|
||||
In addition to various [components](/docs/modules) that are usable with LCEL, LangChain also includes various primitives
|
||||
that help pass around and format data, bind arguments, invoke custom logic, and more.
|
||||
|
||||
This section goes into greater depth on where and how some of these components are useful.

# Quickstart
|
||||
|
||||
In this quickstart we'll show you how to:
|
||||
- Get setup with LangChain, LangSmith and LangServe
|
||||
- Use the most basic and common components of LangChain: prompt templates, models, and output parsers
|
||||
- Use LangChain Expression Language, the protocol that LangChain is built on and which facilitates component chaining
|
||||
- Build a simple application with LangChain
|
||||
- Trace your application with LangSmith
|
||||
- Serve your application with LangServe
|
||||
|
||||
That's a fair amount to cover! Let's dive in.
|
||||
|
||||
## Setup
|
||||
|
||||
### Jupyter Notebook
|
||||
|
||||
This guide (and most of the other guides in the documentation) uses [Jupyter notebooks](https://jupyter.org/) and assumes the reader is as well. Jupyter notebooks are perfect for learning how to work with LLM systems because oftentimes things can go wrong (unexpected output, API down, etc) and going through guides in an interactive environment is a great way to better understand them.
|
||||
|
||||
You do not NEED to go through the guide in a Jupyter Notebook, but it is recommended. See [here](https://jupyter.org/install) for instructions on how to install.
|
||||
|
||||
### Installation
|
||||
|
||||
To install LangChain run:
|
||||
|
||||
import Tabs from '@theme/Tabs';
|
||||
import TabItem from '@theme/TabItem';
|
||||
import CodeBlock from "@theme/CodeBlock";
|
||||
|
||||
<Tabs>
|
||||
<TabItem value="pip" label="Pip" default>
|
||||
<CodeBlock language="bash">pip install langchain</CodeBlock>
|
||||
</TabItem>
|
||||
<TabItem value="conda" label="Conda">
|
||||
<CodeBlock language="bash">conda install langchain -c conda-forge</CodeBlock>
|
||||
</TabItem>
|
||||
</Tabs>
|
||||
|
||||
|
||||
For more details, see our [Installation guide](/docs/get_started/installation).
|
||||
|
||||
### LangSmith
|
||||
|
||||
Many of the applications you build with LangChain will contain multiple steps with multiple invocations of LLM calls.
|
||||
As these applications get more and more complex, it becomes crucial to be able to inspect what exactly is going on inside your chain or agent.
|
||||
The best way to do this is with [LangSmith](https://smith.langchain.com).
|
||||
|
||||
Note that LangSmith is not needed, but it is helpful.
|
||||
If you do want to use LangSmith, after you sign up at the link above, make sure to set your environment variables to start logging traces:
|
||||
|
||||
```shell
|
||||
export LANGCHAIN_TRACING_V2="true"
|
||||
export LANGCHAIN_API_KEY="..."
|
||||
```
|
||||
|
||||
## Building with LangChain
|
||||
|
||||
LangChain enables building application that connect external sources of data and computation to LLMs.
|
||||
In this quickstart, we will walk through a few different ways of doing that.
|
||||
We will start with a simple LLM chain, which just relies on information in the prompt template to respond.
|
||||
Next, we will build a retrieval chain, which fetches data from a separate database and passes that into the prompt template.
|
||||
We will then add in chat history, to create a conversation retrieval chain. This allows you to interact in a chat manner with this LLM, so it remembers previous questions.
|
||||
Finally, we will build an agent - which utilizes an LLM to determine whether or not it needs to fetch data to answer questions.
|
||||
We will cover these at a high level, but there are lot of details to all of these!
|
||||
We will link to relevant docs.
|
||||
|
||||
## LLM Chain
|
||||
|
||||
We'll show how to use models available via API, like OpenAI, and local open source models, using integrations like Ollama.
|
||||
|
||||
<Tabs>
|
||||
<TabItem value="openai" label="OpenAI" default>
|
||||
|
||||
First we'll need to import the LangChain x OpenAI integration package.
|
||||
|
||||
```shell
|
||||
pip install langchain-openai
|
||||
```
|
||||
|
||||
Accessing the API requires an API key, which you can get by creating an account and heading [here](https://platform.openai.com/account/api-keys). Once we have a key we'll want to set it as an environment variable by running:
|
||||
|
||||
```shell
|
||||
export OPENAI_API_KEY="..."
|
||||
```
|
||||
|
||||
We can then initialize the model:
|
||||
|
||||
```python
|
||||
from langchain_openai import ChatOpenAI
|
||||
|
||||
llm = ChatOpenAI()
|
||||
```
|
||||
|
||||
If you'd prefer not to set an environment variable you can pass the key in directly via the `api_key` named parameter when initiating the OpenAI LLM class:
|
||||
|
||||
```python
|
||||
from langchain_openai import ChatOpenAI
|
||||
|
||||
llm = ChatOpenAI(api_key="...")
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
<TabItem value="local" label="Local (using Ollama)">
|
||||
|
||||
[Ollama](https://ollama.ai/) allows you to run open-source large language models, such as Llama 2, locally.
|
||||
|
||||
First, follow [these instructions](https://github.com/jmorganca/ollama) to set up and run a local Ollama instance:
|
||||
|
||||
* [Download](https://ollama.ai/download)
|
||||
* Fetch a model via `ollama pull llama2`
|
||||
|
||||
Then, make sure the Ollama server is running. After that, you can do:
|
||||
```python
|
||||
from langchain_community.llms import Ollama
|
||||
llm = Ollama(model="llama2")
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
<TabItem value="anthropic" label="Anthropic">
|
||||
|
||||
First we'll need to import the LangChain x Anthropic package.
|
||||
|
||||
```shell
|
||||
pip install langchain-anthropic
|
||||
```
|
||||
|
||||
Accessing the API requires an API key, which you can get by creating an account [here](https://claude.ai/login). Once we have a key we'll want to set it as an environment variable by running:
|
||||
|
||||
```shell
|
||||
export ANTHROPIC_API_KEY="..."
|
||||
```
|
||||
|
||||
We can then initialize the model:
|
||||
|
||||
```python
|
||||
from langchain_anthropic import ChatAnthropic
|
||||
|
||||
llm = ChatAnthropic(model="claude-3-sonnet-20240229", temperature=0.2, max_tokens=1024)
|
||||
```
|
||||
|
||||
If you'd prefer not to set an environment variable you can pass the key in directly via the `api_key` named parameter when initiating the Anthropic Chat Model class:
|
||||
|
||||
```python
|
||||
llm = ChatAnthropic(api_key="...")
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
<TabItem value="cohere" label="Cohere">
|
||||
|
||||
First we'll need to import the Cohere SDK package.
|
||||
|
||||
```shell
|
||||
pip install langchain-cohere
|
||||
```
|
||||
|
||||
Accessing the API requires an API key, which you can get by creating an account and heading [here](https://dashboard.cohere.com/api-keys). Once we have a key we'll want to set it as an environment variable by running:
|
||||
|
||||
```shell
|
||||
export COHERE_API_KEY="..."
|
||||
```
|
||||
|
||||
We can then initialize the model:
|
||||
|
||||
```python
|
||||
from langchain_cohere import ChatCohere
|
||||
|
||||
llm = ChatCohere()
|
||||
```
|
||||
|
||||
If you'd prefer not to set an environment variable you can pass the key in directly via the `cohere_api_key` named parameter when initiating the Cohere LLM class:
|
||||
|
||||
```python
|
||||
from langchain_cohere import ChatCohere
|
||||
|
||||
llm = ChatCohere(cohere_api_key="...")
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
</Tabs>
|
||||
|
||||
Once you've installed and initialized the LLM of your choice, we can try using it!
|
||||
Let's ask it what LangSmith is - this is something that wasn't present in the training data so it shouldn't have a very good response.
|
||||
|
||||
```python
|
||||
llm.invoke("how can langsmith help with testing?")
|
||||
```
|
||||
|
||||
We can also guide its response with a prompt template.
|
||||
Prompt templates convert raw user input to better input to the LLM.
|
||||
|
||||
```python
|
||||
from langchain_core.prompts import ChatPromptTemplate
|
||||
prompt = ChatPromptTemplate.from_messages([
|
||||
("system", "You are a world class technical documentation writer."),
|
||||
("user", "{input}")
|
||||
])
|
||||
```
|
||||
|
||||
We can now combine these into a simple LLM chain:
|
||||
|
||||
```python
|
||||
chain = prompt | llm
|
||||
```
|
||||
|
||||
We can now invoke it and ask the same question. It still won't know the answer, but it should respond in a more proper tone for a technical writer!
|
||||
|
||||
```python
|
||||
chain.invoke({"input": "how can langsmith help with testing?"})
|
||||
```
|
||||
|
||||
The output of a ChatModel (and therefore, of this chain) is a message. However, it's often much more convenient to work with strings. Let's add a simple output parser to convert the chat message to a string.
|
||||
|
||||
```python
|
||||
from langchain_core.output_parsers import StrOutputParser
|
||||
|
||||
output_parser = StrOutputParser()
|
||||
```
|
||||
|
||||
We can now add this to the previous chain:
|
||||
|
||||
```python
|
||||
chain = prompt | llm | output_parser
|
||||
```
|
||||
|
||||
We can now invoke it and ask the same question. The answer will now be a string (rather than a ChatMessage).
|
||||
|
||||
```python
|
||||
chain.invoke({"input": "how can langsmith help with testing?"})
|
||||
```
|
||||
|
||||
### Diving Deeper
|
||||
|
||||
We've now successfully set up a basic LLM chain. We only touched on the basics of prompts, models, and output parsers - for a deeper dive into everything mentioned here, see [this section of documentation](/docs/modules/model_io).
|
||||
|
||||
|
||||
## Retrieval Chain
|
||||
|
||||
To properly answer the original question ("how can langsmith help with testing?"), we need to provide additional context to the LLM.
|
||||
We can do this via *retrieval*.
|
||||
Retrieval is useful when you have **too much data** to pass to the LLM directly.
|
||||
You can then use a retriever to fetch only the most relevant pieces and pass those in.
|
||||
|
||||
In this process, we will look up relevant documents from a *Retriever* and then pass them into the prompt.
|
||||
A Retriever can be backed by anything - a SQL table, the internet, etc - but in this instance we will populate a vector store and use that as a retriever. For more information on vectorstores, see [this documentation](/docs/modules/data_connection/vectorstores).
|
||||
|
||||
First, we need to load the data that we want to index. To do this, we will use the WebBaseLoader. This requires installing [BeautifulSoup](https://beautiful-soup-4.readthedocs.io/en/latest/):
|
||||
|
||||
```shell
|
||||
pip install beautifulsoup4
|
||||
```
|
||||
|
||||
After that, we can import and use WebBaseLoader.
|
||||
|
||||
|
||||
```python
|
||||
from langchain_community.document_loaders import WebBaseLoader
|
||||
loader = WebBaseLoader("https://docs.smith.langchain.com/user_guide")
|
||||
|
||||
docs = loader.load()
|
||||
```
|
||||
|
||||
Next, we need to index it into a vectorstore. This requires a few components, namely an [embedding model](/docs/modules/data_connection/text_embedding) and a [vectorstore](/docs/modules/data_connection/vectorstores).
|
||||
|
||||
For embedding models, we once again provide examples for accessing via API or by running local models.
|
||||
|
||||
<Tabs>
|
||||
<TabItem value="openai" label="OpenAI (API)" default>
|
||||
|
||||
Make sure you have the `langchain_openai` package installed an the appropriate environment variables set (these are the same as needed for the LLM).
|
||||
|
||||
```python
|
||||
from langchain_openai import OpenAIEmbeddings
|
||||
|
||||
embeddings = OpenAIEmbeddings()
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
<TabItem value="local" label="Local (using Ollama)">
|
||||
|
||||
Make sure you have Ollama running (same set up as with the LLM).
|
||||
|
||||
```python
|
||||
from langchain_community.embeddings import OllamaEmbeddings
|
||||
|
||||
embeddings = OllamaEmbeddings()
|
||||
```
|
||||
</TabItem>
|
||||
<TabItem value="cohere" label="Cohere (API)" default>
|
||||
|
||||
Make sure you have the `cohere` package installed and the appropriate environment variables set (these are the same as needed for the LLM).
|
||||
|
||||
```python
|
||||
from langchain_cohere.embeddings import CohereEmbeddings
|
||||
|
||||
embeddings = CohereEmbeddings()
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
</Tabs>
|
||||
|
||||
Now, we can use this embedding model to ingest documents into a vectorstore.
|
||||
We will use a simple local vectorstore, [FAISS](/docs/integrations/vectorstores/faiss), for simplicity's sake.
|
||||
|
||||
First we need to install the required packages for that:
|
||||
|
||||
```shell
|
||||
pip install faiss-cpu
|
||||
```
|
||||
|
||||
Then we can build our index:
|
||||
|
||||
```python
|
||||
from langchain_community.vectorstores import FAISS
|
||||
from langchain_text_splitters import RecursiveCharacterTextSplitter
|
||||
|
||||
|
||||
text_splitter = RecursiveCharacterTextSplitter()
|
||||
documents = text_splitter.split_documents(docs)
|
||||
vector = FAISS.from_documents(documents, embeddings)
|
||||
```
|
||||
|
||||
Now that we have this data indexed in a vectorstore, we will create a retrieval chain.
|
||||
This chain will take an incoming question, look up relevant documents, then pass those documents along with the original question into an LLM and ask it to answer the original question.
|
||||
|
||||
First, let's set up the chain that takes a question and the retrieved documents and generates an answer.
|
||||
|
||||
```python
|
||||
from langchain.chains.combine_documents import create_stuff_documents_chain
|
||||
|
||||
prompt = ChatPromptTemplate.from_template("""Answer the following question based only on the provided context:
|
||||
|
||||
<context>
|
||||
{context}
|
||||
</context>
|
||||
|
||||
Question: {input}""")
|
||||
|
||||
document_chain = create_stuff_documents_chain(llm, prompt)
|
||||
```
|
||||
|
||||
If we wanted to, we could run this ourselves by passing in documents directly:
|
||||
|
||||
```python
|
||||
from langchain_core.documents import Document
|
||||
|
||||
document_chain.invoke({
|
||||
"input": "how can langsmith help with testing?",
|
||||
"context": [Document(page_content="langsmith can let you visualize test results")]
|
||||
})
|
||||
```
|
||||
|
||||
However, we want the documents to first come from the retriever we just set up.
|
||||
That way, we can use the retriever to dynamically select the most relevant documents and pass those in for a given question.
|
||||
|
||||
```python
|
||||
from langchain.chains import create_retrieval_chain
|
||||
|
||||
retriever = vector.as_retriever()
|
||||
retrieval_chain = create_retrieval_chain(retriever, document_chain)
|
||||
```
|
||||
|
||||
We can now invoke this chain. This returns a dictionary - the response from the LLM is in the `answer` key
|
||||
|
||||
```python
|
||||
response = retrieval_chain.invoke({"input": "how can langsmith help with testing?"})
|
||||
print(response["answer"])
|
||||
|
||||
# LangSmith offers several features that can help with testing:...
|
||||
```
|
||||
|
||||
This answer should be much more accurate!
|
||||
|
||||
### Diving Deeper
|
||||
|
||||
We've now successfully set up a basic retrieval chain. We only touched on the basics of retrieval - for a deeper dive into everything mentioned here, see [this section of documentation](/docs/modules/data_connection).
|
||||
|
||||
## Conversation Retrieval Chain
|
||||
|
||||
The chain we've created so far can only answer single questions. One of the main types of LLM applications that people are building are chat bots. So how do we turn this chain into one that can answer follow up questions?
|
||||
|
||||
We can still use the `create_retrieval_chain` function, but we need to change two things:
|
||||
|
||||
1. The retrieval method should now not just work on the most recent input, but rather should take the whole history into account.
|
||||
2. The final LLM chain should likewise take the whole history into account
|
||||
|
||||
**Updating Retrieval**
|
||||
|
||||
In order to update retrieval, we will create a new chain. This chain will take in the most recent input (`input`) and the conversation history (`chat_history`) and use an LLM to generate a search query.
|
||||
|
||||
```python
|
||||
from langchain.chains import create_history_aware_retriever
|
||||
from langchain_core.prompts import MessagesPlaceholder
|
||||
|
||||
# First we need a prompt that we can pass into an LLM to generate this search query
|
||||
|
||||
prompt = ChatPromptTemplate.from_messages([
|
||||
MessagesPlaceholder(variable_name="chat_history"),
|
||||
("user", "{input}"),
|
||||
("user", "Given the above conversation, generate a search query to look up to get information relevant to the conversation")
|
||||
])
|
||||
retriever_chain = create_history_aware_retriever(llm, retriever, prompt)
|
||||
```
|
||||
|
||||
We can test this out by passing in an instance where the user asks a follow-up question.
|
||||
|
||||
```python
|
||||
from langchain_core.messages import HumanMessage, AIMessage
|
||||
|
||||
chat_history = [HumanMessage(content="Can LangSmith help test my LLM applications?"), AIMessage(content="Yes!")]
|
||||
retriever_chain.invoke({
|
||||
"chat_history": chat_history,
|
||||
"input": "Tell me how"
|
||||
})
|
||||
```
|
||||
You should see that this returns documents about testing in LangSmith. This is because the LLM generated a new query, combining the chat history with the follow-up question.
|
||||
|
||||
Now that we have this new retriever, we can create a new chain to continue the conversation with these retrieved documents in mind.
|
||||
|
||||
```python
|
||||
prompt = ChatPromptTemplate.from_messages([
|
||||
("system", "Answer the user's questions based on the below context:\n\n{context}"),
|
||||
MessagesPlaceholder(variable_name="chat_history"),
|
||||
("user", "{input}"),
|
||||
])
|
||||
document_chain = create_stuff_documents_chain(llm, prompt)
|
||||
|
||||
retrieval_chain = create_retrieval_chain(retriever_chain, document_chain)
|
||||
```
|
||||
|
||||
We can now test this out end-to-end:
|
||||
|
||||
```python
|
||||
chat_history = [HumanMessage(content="Can LangSmith help test my LLM applications?"), AIMessage(content="Yes!")]
|
||||
retrieval_chain.invoke({
|
||||
"chat_history": chat_history,
|
||||
"input": "Tell me how"
|
||||
})
|
||||
```
|
||||
We can see that this gives a coherent answer - we've successfully turned our retrieval chain into a chatbot!
|
||||
|
||||
## Agent
|
||||
|
||||
We've so far created examples of chains - where each step is known ahead of time.
|
||||
The final thing we will create is an agent - where the LLM decides what steps to take.
|
||||
|
||||
**NOTE: for this example we will only show how to create an agent using OpenAI models, as local models are not reliable enough yet.**
|
||||
|
||||
One of the first things to do when building an agent is to decide what tools it should have access to.
|
||||
For this example, we will give the agent access to two tools:
|
||||
|
||||
1. The retriever we just created. This will let it easily answer questions about LangSmith
|
||||
2. A search tool. This will let it easily answer questions that require up-to-date information.
|
||||
|
||||
First, let's set up a tool for the retriever we just created:
|
||||
|
||||
```python
|
||||
from langchain.tools.retriever import create_retriever_tool
|
||||
|
||||
retriever_tool = create_retriever_tool(
|
||||
retriever,
|
||||
"langsmith_search",
|
||||
"Search for information about LangSmith. For any questions about LangSmith, you must use this tool!",
|
||||
)
|
||||
```
|
||||
|
||||
|
||||
The search tool that we will use is [Tavily](/docs/integrations/retrievers/tavily). This will require an API key (they have generous free tier). After creating it on their platform, you need to set it as an environment variable:
|
||||
|
||||
```shell
|
||||
export TAVILY_API_KEY=...
|
||||
```
|
||||
If you do not want to set up an API key, you can skip creating this tool.
|
||||
|
||||
```python
|
||||
from langchain_community.tools.tavily_search import TavilySearchResults
|
||||
|
||||
search = TavilySearchResults()
|
||||
```
|
||||
|
||||
We can now create a list of the tools we want to work with:
|
||||
|
||||
```python
|
||||
tools = [retriever_tool, search]
|
||||
```
|
||||
|
||||
Now that we have the tools, we can create an agent to use them. We will go over this pretty quickly - for a deeper dive into what exactly is going on, check out the [Agent's Getting Started documentation](/docs/modules/agents)
|
||||
|
||||
Install langchain hub first
|
||||
```bash
|
||||
pip install langchainhub
|
||||
```
|
||||
Install the langchain-openai package
|
||||
To interact with OpenAI we need to use langchain-openai which connects with OpenAI SDK[https://github.com/langchain-ai/langchain/tree/master/libs/partners/openai].
|
||||
```bash
|
||||
pip install langchain-openai
|
||||
```
|
||||
|
||||
Now we can use it to get a predefined prompt
|
||||
|
||||
```python
|
||||
from langchain_openai import ChatOpenAI
|
||||
from langchain import hub
|
||||
from langchain.agents import create_openai_functions_agent
|
||||
from langchain.agents import AgentExecutor
|
||||
|
||||
# Get the prompt to use - you can modify this!
|
||||
prompt = hub.pull("hwchase17/openai-functions-agent")
|
||||
|
||||
# You need to set OPENAI_API_KEY environment variable or pass it as argument `api_key`.
|
||||
llm = ChatOpenAI(model="gpt-3.5-turbo", temperature=0)
|
||||
agent = create_openai_functions_agent(llm, tools, prompt)
|
||||
agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True)
|
||||
```
|
||||
|
||||
We can now invoke the agent and see how it responds! We can ask it questions about LangSmith:
|
||||
|
||||
```python
|
||||
agent_executor.invoke({"input": "how can langsmith help with testing?"})
|
||||
```
|
||||
|
||||
We can ask it about the weather:
|
||||
|
||||
```python
|
||||
agent_executor.invoke({"input": "what is the weather in SF?"})
|
||||
```
|
||||
|
||||
We can have conversations with it:
|
||||
|
||||
```python
|
||||
chat_history = [HumanMessage(content="Can LangSmith help test my LLM applications?"), AIMessage(content="Yes!")]
|
||||
agent_executor.invoke({
|
||||
"chat_history": chat_history,
|
||||
"input": "Tell me how"
|
||||
})
|
||||
```
|
||||
|
||||
### Diving Deeper
|
||||
|
||||
We've now successfully set up a basic agent. We only touched on the basics of agents - for a deeper dive into everything mentioned here, see [this section of documentation](/docs/modules/agents).
|
||||
|
||||
|
||||
## Serving with LangServe
|
||||
|
||||
Now that we've built an application, we need to serve it. That's where LangServe comes in.
|
||||
LangServe helps developers deploy LangChain chains as a REST API. You do not need to use LangServe to use LangChain, but in this guide we'll show how you can deploy your app with LangServe.
|
||||
|
||||
While the first part of this guide was intended to be run in a Jupyter Notebook, we will now move out of that. We will be creating a Python file and then interacting with it from the command line.
|
||||
|
||||
Install with:
|
||||
```bash
|
||||
pip install "langserve[all]"
|
||||
```
|
||||
|
||||
### Server
|
||||
|
||||
To create a server for our application we'll make a `serve.py` file. This will contain our logic for serving our application. It consists of three things:
|
||||
1. The definition of our chain that we just built above
|
||||
2. Our FastAPI app
|
||||
3. A definition of a route from which to serve the chain, which is done with `langserve.add_routes`
|
||||
|
||||
```python
|
||||
#!/usr/bin/env python
|
||||
from typing import List
|
||||
|
||||
from fastapi import FastAPI
|
||||
from langchain_core.prompts import ChatPromptTemplate
|
||||
from langchain_openai import ChatOpenAI
|
||||
from langchain_community.document_loaders import WebBaseLoader
|
||||
from langchain_openai import OpenAIEmbeddings
|
||||
from langchain_community.vectorstores import FAISS
|
||||
from langchain_text_splitters import RecursiveCharacterTextSplitter
|
||||
from langchain.tools.retriever import create_retriever_tool
|
||||
from langchain_community.tools.tavily_search import TavilySearchResults
|
||||
from langchain import hub
|
||||
from langchain.agents import create_openai_functions_agent
|
||||
from langchain.agents import AgentExecutor
|
||||
from langchain.pydantic_v1 import BaseModel, Field
|
||||
from langchain_core.messages import BaseMessage
|
||||
from langserve import add_routes
|
||||
|
||||
# 1. Load Retriever
|
||||
loader = WebBaseLoader("https://docs.smith.langchain.com/user_guide")
|
||||
docs = loader.load()
|
||||
text_splitter = RecursiveCharacterTextSplitter()
|
||||
documents = text_splitter.split_documents(docs)
|
||||
embeddings = OpenAIEmbeddings()
|
||||
vector = FAISS.from_documents(documents, embeddings)
|
||||
retriever = vector.as_retriever()
|
||||
|
||||
# 2. Create Tools
|
||||
retriever_tool = create_retriever_tool(
|
||||
retriever,
|
||||
"langsmith_search",
|
||||
"Search for information about LangSmith. For any questions about LangSmith, you must use this tool!",
|
||||
)
|
||||
search = TavilySearchResults()
|
||||
tools = [retriever_tool, search]
|
||||
|
||||
|
||||
# 3. Create Agent
|
||||
prompt = hub.pull("hwchase17/openai-functions-agent")
|
||||
llm = ChatOpenAI(model="gpt-3.5-turbo", temperature=0)
|
||||
agent = create_openai_functions_agent(llm, tools, prompt)
|
||||
agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True)
|
||||
|
||||
|
||||
# 4. App definition
|
||||
app = FastAPI(
|
||||
title="LangChain Server",
|
||||
version="1.0",
|
||||
description="A simple API server using LangChain's Runnable interfaces",
|
||||
)
|
||||
|
||||
# 5. Adding chain route
|
||||
|
||||
# We need to add these input/output schemas because the current AgentExecutor
|
||||
# is lacking in schemas.
|
||||
|
||||
class Input(BaseModel):
|
||||
input: str
|
||||
chat_history: List[BaseMessage] = Field(
|
||||
...,
|
||||
extra={"widget": {"type": "chat", "input": "location"}},
|
||||
)
|
||||
|
||||
|
||||
class Output(BaseModel):
|
||||
output: str
|
||||
|
||||
add_routes(
|
||||
app,
|
||||
agent_executor.with_types(input_type=Input, output_type=Output),
|
||||
path="/agent",
|
||||
)
|
||||
|
||||
if __name__ == "__main__":
|
||||
import uvicorn
|
||||
|
||||
uvicorn.run(app, host="localhost", port=8000)
|
||||
```
|
||||
|
||||
And that's it! If we execute this file:
|
||||
```bash
|
||||
python serve.py
|
||||
```
|
||||
we should see our chain being served at localhost:8000.
|
||||
|
||||
### Playground
|
||||
|
||||
Every LangServe service comes with a simple built-in UI for configuring and invoking the application with streaming output and visibility into intermediate steps.
|
||||
Head to http://localhost:8000/agent/playground/ to try it out! Pass in the same question as before - "how can langsmith help with testing?" - and it should respond same as before.
|
||||
|
||||
### Client
|
||||
|
||||
Now let's set up a client for programmatically interacting with our service. We can easily do this with the `[langserve.RemoteRunnable](/docs/langserve#client)`.
|
||||
Using this, we can interact with the served chain as if it were running client-side.
|
||||
|
||||
```python
|
||||
from langserve import RemoteRunnable
|
||||
|
||||
remote_chain = RemoteRunnable("http://localhost:8000/agent/")
|
||||
remote_chain.invoke({
|
||||
"input": "how can langsmith help with testing?",
|
||||
"chat_history": [] # Providing an empty list as this is the first call
|
||||
})
|
||||
```
|
||||
|
||||
To learn more about the many other features of LangServe [head here](/docs/langserve).
|
||||
|
||||
## Next steps
|
||||
|
||||
We've touched on how to build an application with LangChain, how to trace it with LangSmith, and how to serve it with LangServe.
|
||||
There are a lot more features in all three of these than we can cover here.
|
||||
To continue on your journey, we recommend you read the following (in order):
|
||||
|
||||
- All of these features are backed by [LangChain Expression Language (LCEL)](/docs/expression_language) - a way to chain these components together. Check out that documentation to better understand how to create custom chains.
|
||||
- [Model IO](/docs/modules/model_io) covers more details of prompts, LLMs, and output parsers.
|
||||
- [Retrieval](/docs/modules/data_connection) covers more details of everything related to retrieval
|
||||
- [Agents](/docs/modules/agents) covers details of everything related to agents
|
||||
- Explore common [end-to-end use cases](/docs/use_cases/) and [template applications](/docs/templates)

# Debugging
|
||||
|
||||
If you're building with LLMs, at some point something will break, and you'll need to debug. A model call will fail, or the model output will be misformatted, or there will be some nested model calls and it won't be clear where along the way an incorrect output was created.
|
||||
|
||||
Here are a few different tools and functionalities to aid in debugging.
|
||||
|
||||
|
||||
|
||||
## Tracing
|
||||
|
||||
Platforms with tracing capabilities like [LangSmith](/docs/langsmith/) are the most comprehensive solutions for debugging. These platforms make it easy to not only log and visualize LLM apps, but also to actively debug, test and refine them.
|
||||
|
||||
When building production-grade LLM applications, platforms like this are essential.
|
||||
|
||||
![Screenshot of the LangSmith debugging interface showing an AgentExecutor run with input and output details, and a run tree visualization.](../../../static/img/run_details.png "LangSmith Debugging Interface")
|
||||
|
||||
## `set_debug` and `set_verbose`
|
||||
|
||||
If you're prototyping in Jupyter Notebooks or running Python scripts, it can be helpful to print out the intermediate steps of a Chain run.
|
||||
|
||||
There are a number of ways to enable printing at varying degrees of verbosity.
|
||||
|
||||
Let's suppose we have a simple agent, and want to visualize the actions it takes and tool outputs it receives. Without any debugging, here's what we see:
|
||||
|
||||
|
||||
```python
|
||||
from langchain.agents import AgentType, initialize_agent, load_tools
|
||||
from langchain_openai import ChatOpenAI
|
||||
|
||||
llm = ChatOpenAI(model="gpt-4", temperature=0)
|
||||
tools = load_tools(["ddg-search", "llm-math"], llm=llm)
|
||||
agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION)
|
||||
```
|
||||
|
||||
|
||||
```python
|
||||
agent.run("Who directed the 2023 film Oppenheimer and what is their age? What is their age in days (assume 365 days per year)?")
|
||||
```
|
||||
|
||||
<CodeOutputBlock lang="python">
|
||||
|
||||
```
|
||||
'The director of the 2023 film Oppenheimer is Christopher Nolan and he is approximately 19345 days old in 2023.'
|
||||
```
|
||||
|
||||
</CodeOutputBlock>
|
||||
|
||||
### `set_debug(True)`
|
||||
|
||||
Setting the global `debug` flag will cause all LangChain components with callback support (chains, models, agents, tools, retrievers) to print the inputs they receive and outputs they generate. This is the most verbose setting and will fully log raw inputs and outputs.
|
||||
|
||||
|
||||
```python
|
||||
from langchain.globals import set_debug
|
||||
|
||||
set_debug(True)
|
||||
|
||||
agent.run("Who directed the 2023 film Oppenheimer and what is their age? What is their age in days (assume 365 days per year)?")
|
||||
```
|
||||
|
||||

## Other callbacks
|
||||
|
||||
`Callbacks` are what we use to execute any functionality within a component outside the primary component logic. All of the above solutions use `Callbacks` under the hood to log intermediate steps of components. There are a number of `Callbacks` relevant for debugging that come with LangChain out of the box, like the [FileCallbackHandler](/docs/modules/callbacks/filecallbackhandler). You can also implement your own callbacks to execute custom functionality.
|
||||
|
||||
See here for more info on [Callbacks](/docs/modules/callbacks/), how to use them, and customize them.

# Extending LangChain
|
||||
|
||||
Extending LangChain's base abstractions, whether you're planning to contribute back to the open-source repo or build a bespoke internal integration, is encouraged.
|
||||
|
||||
Check out these guides for building your own custom classes for the following modules:
|
||||
|
||||
- [Chat models](/docs/modules/model_io/chat/custom_chat_model) for interfacing with chat-tuned language models.
|
||||
- [LLMs](/docs/modules/model_io/llms/custom_llm) for interfacing with text language models.
|
||||
- [Output parsers](/docs/modules/model_io/output_parsers/custom) for handling language model outputs.

"# Run LLMs locally\n",
|

"\n",
|
||||
"## Use case\n",
|
||||
"\n",
|
||||
"The popularity of projects like [PrivateGPT](https://github.com/imartinez/privateGPT), [llama.cpp](https://github.com/ggerganov/llama.cpp), [Ollama](https://github.com/ollama/ollama), [GPT4All](https://github.com/nomic-ai/gpt4all), [llamafile](https://github.com/Mozilla-Ocho/llamafile), and others underscore the demand to run LLMs locally (on your own device).\n",
|
||||
"\n",
|
||||
"This has at least two important benefits:\n",
|
||||
"\n",
|
||||
"1. `Privacy`: Your data is not sent to a third party, and it is not subject to the terms of service of a commercial service\n",
|
||||
"2. `Cost`: There is no inference fee, which is important for token-intensive applications (e.g., [long-running simulations](https://twitter.com/RLanceMartin/status/1691097659262820352?s=20), summarization)\n",
|
||||
"\n",
|
||||
"## Overview\n",
|
||||
"\n",
|
||||
"Running an LLM locally requires a few things:\n",
|
||||
"\n",
|
||||
"1. `Open-source LLM`: An open-source LLM that can be freely modified and shared \n",
|
||||
"2. `Inference`: Ability to run this LLM on your device w/ acceptable latency\n",
|
||||
"\n",
|
||||
"### Open-source LLMs\n",
|
||||
"\n",
|
||||
"Users can now gain access to a rapidly growing set of [open-source LLMs](https://cameronrwolfe.substack.com/p/the-history-of-open-source-llms-better). \n",
|
||||
"\n",
|
||||
"These LLMs can be assessed across at least two dimensions (see figure):\n",
|
||||
" \n",
|
||||
"1. `Base model`: What is the base-model and how was it trained?\n",
|
||||
"2. `Fine-tuning approach`: Was the base-model fine-tuned and, if so, what [set of instructions](https://cameronrwolfe.substack.com/p/beyond-llama-the-power-of-open-llms#%C2%A7alpaca-an-instruction-following-llama-model) was used?\n",

"![Image description](../../../static/img/OSS_LLM_overview.png)\n",

"1. [LmSys](https://chat.lmsys.org/?arena)\n",

"2. [GPT4All](https://gpt4all.io/index.html)\n",

|
||||
"\n",
|
||||
"### Inference\n",
|
||||
"\n",
|
||||
"A few frameworks for this have emerged to support inference of open-source LLMs on various devices:\n",
|
||||
"\n",
|
||||
"1. [`llama.cpp`](https://github.com/ggerganov/llama.cpp): C++ implementation of llama inference code with [weight optimization / quantization](https://finbarr.ca/how-is-llama-cpp-possible/)\n",
|
||||
"2. [`gpt4all`](https://docs.gpt4all.io/index.html): Optimized C backend for inference\n",
|
||||
"3. [`Ollama`](https://ollama.ai/): Bundles model weights and environment into an app that runs on device and serves the LLM\n",
|
||||
"4. [`llamafile`](https://github.com/Mozilla-Ocho/llamafile): Bundles model weights and everything needed to run the model in a single file, allowing you to run the LLM locally from this file without any additional installation steps\n",
|
||||
"\n",
|
||||
"In general, these frameworks will do a few things:\n",
|
||||
"\n",
|
||||
"1. `Quantization`: Reduce the memory footprint of the raw model weights\n",
|
||||
"2. `Efficient implementation for inference`: Support inference on consumer hardware (e.g., CPU or laptop GPU)\n",
|
||||
"\n",
|
||||
"In particular, see [this excellent post](https://finbarr.ca/how-is-llama-cpp-possible/) on the importance of quantization.\n",
|
||||
"\n",
|
||||
"![Image description](../../../static/img/llama-memory-weights.png)\n",
|
||||
"\n",
|
||||
"With less precision, we radically decrease the memory needed to store the LLM in memory.\n",
|
||||
"\n",
|
||||
"In addition, we can see the importance of GPU memory bandwidth [sheet](https://docs.google.com/spreadsheets/d/1OehfHHNSn66BP2h3Bxp2NJTVX97icU0GmCXF6pK23H8/edit#gid=0)!\n",
|

If he failed to do this, he would have been killed along with all those people who were on board the spacecraft.\\n3rd, let's imagine that Neil Armstrong successfully landed his spacecraft on the moon and made it back to Earth safely. The next step was for him to be hailed as a hero by his people back home. It took years before Neil Armstrong became an American hero.\\n4th, let's take another step back. Let's imagine that Neil Armstrong wasn't hailed as a hero, and instead, he was just forgotten. This happened in the 1970s. Neil Armstrong wasn't recognized for his remarkable achievement on the moon until after he died.\\n5th, let's take another step back. Let's imagine that Neil Armstrong didn't die in the 1970s and instead, lived to be a hundred years old. This happened in 2036. In the year 2036, Neil Armstrong would have been a centenarian.\\nNow, let's think about the present. Neil Armstrong is still alive. He turned 95 years old on July 20th, 2018. If he were to die now, his achievement of becoming the first human being to set foot on the moon would remain an unforgettable moment in history.\\nI hope this helps you understand the significance and importance of Neil Armstrong's achievement on the moon!\""

|
||||
- Pydantic v2 was released in June, 2023 (https://docs.pydantic.dev/2.0/blog/pydantic-v2-final/)
|
||||
- v2 contains has a number of breaking changes (https://docs.pydantic.dev/2.0/migration/)
|
||||
- Pydantic v2 and v1 are under the same package name, so both versions cannot be installed at the same time

As of `langchain>=0.0.267`, LangChain will allow users to install either Pydantic V1 or V2.
|
||||
* Internally LangChain will continue to [use V1](https://docs.pydantic.dev/latest/migration/#continue-using-pydantic-v1-features).
|
||||
* During this time, users can pin their pydantic version to v1 to avoid breaking changes, or start a partial
|
||||
migration using pydantic v2 throughout their code, but avoiding mixing v1 and v2 code for LangChain (see below).
|
||||
|
||||
User can either pin to pydantic v1, and upgrade their code in one go once LangChain has migrated to v2 internally, or they can start a partial migration to v2, but must avoid mixing v1 and v2 code for LangChain.
|
||||
|
||||
Below are two examples of showing how to avoid mixing pydantic v1 and v2 code in
|
||||
the case of inheritance and in the case of passing objects to LangChain.
|
||||
|
||||
**Example 1: Extending via inheritance**
|
||||
|
||||
**YES**
|
||||
|
||||
```python
|
||||
from pydantic.v1 import root_validator, validator
|
||||
|
||||
class CustomTool(BaseTool): # BaseTool is v1 code
|
||||
x: int = Field(default=1)
|
||||
|
||||
def _run(*args, **kwargs):
|
||||
return "hello"
|
||||
|
||||
@validator('x') # v1 code
|
||||
@classmethod
|
||||
def validate_x(cls, x: int) -> int:
|
||||
return 1
|
||||
|
||||
|
||||
CustomTool(
|
||||
name='custom_tool',
|
||||
description="hello",
|
||||
x=1,
|
||||
)
|
||||
```
|
||||
|
||||
Mixing Pydantic v2 primitives with Pydantic v1 primitives can raise cryptic errors
|
||||
|
||||
**NO**
|
||||
|
||||
```python
|
||||
from pydantic import Field, field_validator # pydantic v2
|
||||
|
||||
class CustomTool(BaseTool): # BaseTool is v1 code
|
||||
x: int = Field(default=1)
|
||||
|
||||
def _run(*args, **kwargs):
|
||||
return "hello"
|
||||
|
||||
@field_validator('x') # v2 code
|
||||
@classmethod
|
||||
def validate_x(cls, x: int) -> int:
|
||||
return 1
|
||||
|
||||
|
||||
CustomTool(
|
||||
name='custom_tool',
|
||||
description="hello",
|
||||
x=1,
|
||||
)
|
||||
```
|
||||
|
||||
**Example 2: Passing objects to LangChain**
|
||||
|
||||
**YES**
|
||||
|
||||
```python
|
||||
from langchain_core.tools import Tool
|
||||
from pydantic.v1 import BaseModel, Field # <-- Uses v1 namespace
|
||||
|
||||
class CalculatorInput(BaseModel):
|
||||
question: str = Field()
|
||||
|
||||
Tool.from_function( # <-- tool uses v1 namespace

name="Calculator",
|
||||
description="useful for when you need to answer questions about math",
|
||||
args_schema=CalculatorInput
|
||||
)
|
||||
```
|
||||
|
||||
**NO**
|
||||
|
||||
```python
|
||||
from langchain_core.tools import Tool
|
||||
from pydantic import BaseModel, Field # <-- Uses v2 namespace
|

# Deployment
|
||||
|
||||
In today's fast-paced technological landscape, the use of Large Language Models (LLMs) is rapidly expanding. As a result, it is crucial for developers to understand how to effectively deploy these models in production environments. LLM interfaces typically fall into two categories:
|
||||
|
||||
- **Case 1: Utilizing External LLM Providers (OpenAI, Anthropic, etc.)**
|
||||
In this scenario, most of the computational burden is handled by the LLM providers, while LangChain simplifies the implementation of business logic around these services. This approach includes features such as prompt templating, chat message generation, caching, vector embedding database creation, preprocessing, etc.
|
||||
|
||||
- **Case 2: Self-hosted Open-Source Models**
|
||||
Alternatively, developers can opt to use smaller, yet comparably capable, self-hosted open-source LLM models. This approach can significantly decrease costs, latency, and privacy concerns associated with transferring data to external LLM providers.
|
||||
|
||||
Regardless of the framework that forms the backbone of your product, deploying LLM applications comes with its own set of challenges. It's vital to understand the trade-offs and key considerations when evaluating serving frameworks.
|
||||
|
||||
## Outline
|
||||
|
||||
This guide aims to provide a comprehensive overview of the requirements for deploying LLMs in a production setting, focusing on:
|
||||
|
||||
- **Designing a Robust LLM Application Service**
|
||||
- **Maintaining Cost-Efficiency**
|
||||
- **Ensuring Rapid Iteration**
|
||||
|
||||
Understanding these components is crucial when assessing serving systems. LangChain integrates with several open-source projects designed to tackle these issues, providing a robust framework for productionizing your LLM applications. Some notable frameworks include:
|
||||
|
||||
- [Ray Serve](/docs/integrations/providers/ray_serve)
|
||||
- [BentoML](https://github.com/bentoml/BentoML)
|
||||
- [OpenLLM](/docs/integrations/providers/openllm)
|
||||
- [Modal](/docs/integrations/providers/modal)
|
||||
- [Jina](/docs/integrations/providers/jina)
|
||||
|
||||
These links will provide further information on each ecosystem, assisting you in finding the best fit for your LLM deployment needs.
|
||||
|
||||
## Designing a Robust LLM Application Service
|
||||
|
||||
When deploying an LLM service in production, it's imperative to provide a seamless user experience free from outages. Achieving 24/7 service availability involves creating and maintaining several sub-systems surrounding your application.
|
||||
|
||||
### Monitoring
|
||||
|
||||
Monitoring forms an integral part of any system running in a production environment. In the context of LLMs, it is essential to monitor both performance and quality metrics.
|
||||
|
||||
**Performance Metrics:** These metrics provide insights into the efficiency and capacity of your model. Here are some key examples:
|
||||
|
||||
- Query per second (QPS): This measures the number of queries your model processes in a second, offering insights into its utilization.
|
||||
- Latency: This metric quantifies the delay from when your client sends a request to when they receive a response.
|
||||
- Tokens Per Second (TPS): This represents the number of tokens your model can generate in a second.
|
||||
|
||||
**Quality Metrics:** These metrics are typically customized according to the business use-case. For instance, how does the output of your system compare to a baseline, such as a previous version? Although these metrics can be calculated offline, you need to log the necessary data to use them later.
|
||||
|
||||
### Fault tolerance
|
||||
|
||||
Your application may encounter errors such as exceptions in your model inference or business logic code, causing failures and disrupting traffic. Other potential issues could arise from the machine running your application, such as unexpected hardware breakdowns or loss of spot-instances during high-demand periods. One way to mitigate these risks is by increasing redundancy through replica scaling and implementing recovery mechanisms for failed replicas. However, model replicas aren't the only potential points of failure. It's essential to build resilience against various failures that could occur at any point in your stack.
|
||||
|
||||
|
||||
### Zero down time upgrade
|
||||
|
||||
System upgrades are often necessary but can result in service disruptions if not handled correctly. One way to prevent downtime during upgrades is by implementing a smooth transition process from the old version to the new one. Ideally, the new version of your LLM service is deployed, and traffic gradually shifts from the old to the new version, maintaining a constant QPS throughout the process.
|
||||
|
||||
|
||||
### Load balancing
|
||||
|
||||
Load balancing, in simple terms, is a technique to distribute work evenly across multiple computers, servers, or other resources to optimize the utilization of the system, maximize throughput, minimize response time, and avoid overload of any single resource. Think of it as a traffic officer directing cars (requests) to different roads (servers) so that no single road becomes too congested.
|
||||
|
||||
There are several strategies for load balancing. For example, one common method is the *Round Robin* strategy, where each request is sent to the next server in line, cycling back to the first when all servers have received a request. This works well when all servers are equally capable. However, if some servers are more powerful than others, you might use a *Weighted Round Robin* or *Least Connections* strategy, where more requests are sent to the more powerful servers, or to those currently handling the fewest active requests. Let's imagine you're running a LLM chain. If your application becomes popular, you could have hundreds or even thousands of users asking questions at the same time. If one server gets too busy (high load), the load balancer would direct new requests to another server that is less busy. This way, all your users get a timely response and the system remains stable.
|
||||
|
||||
|
||||
|
||||
## Maintaining Cost-Efficiency and Scalability
|
||||
|
||||
Deploying LLM services can be costly, especially when you're handling a large volume of user interactions. Charges by LLM providers are usually based on tokens used, making a chat system inference on these models potentially expensive. However, several strategies can help manage these costs without compromising the quality of the service.
|
||||
|
||||
|
||||
### Self-hosting models
|
||||
|
||||
Several smaller and open-source LLMs are emerging to tackle the issue of reliance on LLM providers. Self-hosting allows you to maintain similar quality to LLM provider models while managing costs. The challenge lies in building a reliable, high-performing LLM serving system on your own machines.
|
||||
|
||||
### Resource Management and Auto-Scaling
|
||||
|
||||
Computational logic within your application requires precise resource allocation. For instance, if part of your traffic is served by an OpenAI endpoint and another part by a self-hosted model, it's crucial to allocate suitable resources for each. Auto-scaling—adjusting resource allocation based on traffic—can significantly impact the cost of running your application. This strategy requires a balance between cost and responsiveness, ensuring neither resource over-provisioning nor compromised application responsiveness.
|
||||
|
||||
### Utilizing Spot Instances
|
||||
|
||||
On platforms like AWS, spot instances offer substantial cost savings, typically priced at about a third of on-demand instances. The trade-off is a higher crash rate, necessitating a robust fault-tolerance mechanism for effective use.
|
||||
|
||||
### Independent Scaling
|
||||
|
||||
When self-hosting your models, you should consider independent scaling. For example, if you have two translation models, one fine-tuned for French and another for Spanish, incoming requests might necessitate different scaling requirements for each.
|
||||
|
||||
### Batching requests
|
||||
|
||||
In the context of Large Language Models, batching requests can enhance efficiency by better utilizing your GPU resources. GPUs are inherently parallel processors, designed to handle multiple tasks simultaneously. If you send individual requests to the model, the GPU might not be fully utilized as it's only working on a single task at a time. On the other hand, by batching requests together, you're allowing the GPU to work on multiple tasks at once, maximizing its utilization and improving inference speed. This not only leads to cost savings but can also improve the overall latency of your LLM service.
|
||||
|
||||
|
||||
In summary, managing costs while scaling your LLM services requires a strategic approach. Utilizing self-hosting models, managing resources effectively, employing auto-scaling, using spot instances, independently scaling models, and batching requests are key strategies to consider. Open-source libraries such as Ray Serve and BentoML are designed to deal with these complexities.
|
||||
|
||||
|
||||
|
||||
## Ensuring Rapid Iteration
|
||||
|
||||
The LLM landscape is evolving at an unprecedented pace, with new libraries and model architectures being introduced constantly. Consequently, it's crucial to avoid tying yourself to a solution specific to one particular framework. This is especially relevant in serving, where changes to your infrastructure can be time-consuming, expensive, and risky. Strive for infrastructure that is not locked into any specific machine learning library or framework, but instead offers a general-purpose, scalable serving layer. Here are some aspects where flexibility plays a key role:
|
||||
|
||||
### Model composition
|
||||
|
||||
Deploying systems like LangChain demands the ability to piece together different models and connect them via logic. Take the example of building a natural language input SQL query engine. Querying an LLM and obtaining the SQL command is only part of the system. You need to extract metadata from the connected database, construct a prompt for the LLM, run the SQL query on an engine, collect and feedback the response to the LLM as the query runs, and present the results to the user. This demonstrates the need to seamlessly integrate various complex components built in Python into a dynamic chain of logical blocks that can be served together.
|
||||
|
||||
## Cloud providers
|
||||
|
||||
Many hosted solutions are restricted to a single cloud provider, which can limit your options in today's multi-cloud world. Depending on where your other infrastructure components are built, you might prefer to stick with your chosen cloud provider.
|
||||
|
||||
|
||||
## Infrastructure as Code (IaC)
|
||||
|
||||
Rapid iteration also involves the ability to recreate your infrastructure quickly and reliably. This is where Infrastructure as Code (IaC) tools like Terraform, CloudFormation, or Kubernetes YAML files come into play. They allow you to define your infrastructure in code files, which can be version controlled and quickly deployed, enabling faster and more reliable iterations.
|
||||
|
||||
|
||||
## CI/CD
|
||||
|
||||
In a fast-paced environment, implementing CI/CD pipelines can significantly speed up the iteration process. They help automate the testing and deployment of your LLM applications, reducing the risk of errors and enabling faster feedback and iteration.

# Comparison Evaluators
|
||||
|
||||
Comparison evaluators in LangChain help measure two different chains or LLM outputs. These evaluators are helpful for comparative analyses, such as A/B testing between two language models, or comparing different versions of the same model. They can also be useful for things like generating preference scores for ai-assisted reinforcement learning.
|
||||
|
||||
These evaluators inherit from the `PairwiseStringEvaluator` class, providing a comparison interface for two strings - typically, the outputs from two different prompts or models, or two versions of the same model. In essence, a comparison evaluator performs an evaluation on a pair of strings and returns a dictionary containing the evaluation score and other relevant details.
|
||||
|
||||
To create a custom comparison evaluator, inherit from the `PairwiseStringEvaluator` class and overwrite the `_evaluate_string_pairs` method. If you require asynchronous evaluation, also overwrite the `_aevaluate_string_pairs` method.
|
||||
|
||||
Here's a summary of the key methods and properties of a comparison evaluator:
|
||||
|
||||
- `evaluate_string_pairs`: Evaluate the output string pairs. This function should be overwritten when creating custom evaluators.
|
||||
- `aevaluate_string_pairs`: Asynchronously evaluate the output string pairs. This function should be overwritten for asynchronous evaluation.
|
||||
- `requires_input`: This property indicates whether this evaluator requires an input string.
|
||||
- `requires_reference`: This property specifies whether this evaluator requires a reference label.
|
||||
|
||||
:::note LangSmith Support
|
||||
The [run_on_dataset](https://api.python.langchain.com/en/latest/langchain_api_reference.html#module-langchain.smith) evaluation method is designed to evaluate only a single model at a time, and thus, doesn't support these evaluators.
|
||||
:::
|
||||
|
||||
Detailed information about creating custom evaluators and the available built-in comparison evaluators is provided in the following sections.

# Evaluation
|
||||
|
||||
Building applications with language models involves many moving parts. One of the most critical components is ensuring that the outcomes produced by your models are reliable and useful across a broad array of inputs, and that they work well with your application's other software components. Ensuring reliability usually boils down to some combination of application design, testing & evaluation, and runtime checks.
|
||||
|
||||
The guides in this section review the APIs and functionality LangChain provides to help you better evaluate your applications. Evaluation and testing are both critical when thinking about deploying LLM applications, since production environments require repeatable and useful outcomes.
|
||||
|
||||
LangChain offers various types of evaluators to help you measure performance and integrity on diverse data, and we hope to encourage the community to create and share other useful evaluators so everyone can improve. These docs will introduce the evaluator types, how to use them, and provide some examples of their use in real-world scenarios.
|
||||
These built-in evaluators all integrate smoothly with [LangSmith](/docs/langsmith), and allow you to create feedback loops that improve your application over time and prevent regressions.
|
||||
|
||||
Each evaluator type in LangChain comes with ready-to-use implementations and an extensible API that allows for customization according to your unique requirements. Here are some of the types of evaluators we offer:
|
||||
|
||||
- [String Evaluators](/docs/guides/productionization/evaluation/string/): These evaluators assess the predicted string for a given input, usually comparing it against a reference string.
|
||||
- [Trajectory Evaluators](/docs/guides/productionization/evaluation/trajectory/): These are used to evaluate the entire trajectory of agent actions.
|
||||
- [Comparison Evaluators](/docs/guides/productionization/evaluation/comparison/): These evaluators are designed to compare predictions from two runs on a common input.
|
||||
|
||||
These evaluators can be used across various scenarios and can be applied to different chain and LLM implementations in the LangChain library.
|
||||
|
||||
We also are working to share guides and cookbooks that demonstrate how to use these evaluators in real-world scenarios, such as:
|
||||
|
||||
- [Chain Comparisons](/docs/guides/productionization/evaluation/examples/comparisons): This example uses a comparison evaluator to predict the preferred output. It reviews ways to measure confidence intervals to select statistically significant differences in aggregate preference scores across different models or prompts.
|
||||
|
||||
|
||||
## LangSmith Evaluation
|
||||
|
||||
LangSmith provides an integrated evaluation and tracing framework that allows you to check for regressions, compare systems, and easily identify and fix any sources of errors and performance issues. Check out the docs on [LangSmith Evaluation](https://docs.smith.langchain.com/evaluation) and additional [cookbooks](https://docs.smith.langchain.com/cookbook) for more detailed information on evaluating your applications.
|
||||
|
||||
## LangChain benchmarks
|
||||
|
||||
Your application quality is a function both of the LLM you choose and the prompting and data retrieval strategies you employ to provide model contexet. We have published a number of benchmark tasks within the [LangChain Benchmarks](https://langchain-ai.github.io/langchain-benchmarks/) package to grade different LLM systems on tasks such as:
|
||||
|
||||
- Agent tool use
|
||||
- Retrieval-augmented question-answering
|
||||
- Structured Extraction
|
||||
|
||||
Check out the docs for examples and leaderboard information.
|
||||
|
||||
## Reference Docs
|
||||
|
||||
For detailed information on the available evaluators, including how to instantiate, configure, and customize them, check out the [reference documentation](https://api.python.langchain.com/en/latest/langchain_api_reference.html#module-langchain.evaluation) directly.

# String Evaluators
|
||||
|
||||
A string evaluator is a component within LangChain designed to assess the performance of a language model by comparing its generated outputs (predictions) to a reference string or an input. This comparison is a crucial step in the evaluation of language models, providing a measure of the accuracy or quality of the generated text.
|
||||
|
||||
In practice, string evaluators are typically used to evaluate a predicted string against a given input, such as a question or a prompt. Often, a reference label or context string is provided to define what a correct or ideal response would look like. These evaluators can be customized to tailor the evaluation process to fit your application's specific requirements.
|
||||
|
||||
To create a custom string evaluator, inherit from the `StringEvaluator` class and implement the `_evaluate_strings` method. If you require asynchronous support, also implement the `_aevaluate_strings` method.
|
||||
|
||||
Here's a summary of the key attributes and methods associated with a string evaluator:
|
||||
|
||||
- `evaluation_name`: Specifies the name of the evaluation.
|
||||
- `requires_input`: Boolean attribute that indicates whether the evaluator requires an input string. If True, the evaluator will raise an error when the input isn't provided. If False, a warning will be logged if an input _is_ provided, indicating that it will not be considered in the evaluation.
|
||||
- `requires_reference`: Boolean attribute specifying whether the evaluator requires a reference label. If True, the evaluator will raise an error when the reference isn't provided. If False, a warning will be logged if a reference _is_ provided, indicating that it will not be considered in the evaluation.
|
||||
|
||||
String evaluators also implement the following methods:
|
||||
|
||||
- `aevaluate_strings`: Asynchronously evaluates the output of the Chain or Language Model, with support for optional input and label.
|
||||
- `evaluate_strings`: Synchronously evaluates the output of the Chain or Language Model, with support for optional input and label.
|
||||
|
||||
The following sections provide detailed information on available string evaluator implementations as well as how to create a custom string evaluator.

# Trajectory Evaluators
|
||||
|
||||
Trajectory Evaluators in LangChain provide a more holistic approach to evaluating an agent. These evaluators assess the full sequence of actions taken by an agent and their corresponding responses, which we refer to as the "trajectory". This allows you to better measure an agent's effectiveness and capabilities.
|
||||
|
||||
A Trajectory Evaluator implements the `AgentTrajectoryEvaluator` interface, which requires two main methods:
|
||||
|
||||
- `evaluate_agent_trajectory`: This method synchronously evaluates an agent's trajectory.
|
||||
- `aevaluate_agent_trajectory`: This asynchronous counterpart allows evaluations to be run in parallel for efficiency.
|
||||
|
||||
Both methods accept three main parameters:
|
||||
|
||||
- `input`: The initial input given to the agent.
|
||||
- `prediction`: The final predicted response from the agent.
|
||||
- `agent_trajectory`: The intermediate steps taken by the agent, given as a list of tuples.
|
||||
|
||||
These methods return a dictionary. It is recommended that custom implementations return a `score` (a float indicating the effectiveness of the agent) and `reasoning` (a string explaining the reasoning behind the score).
|
||||
|
||||
You can capture an agent's trajectory by initializing the agent with the `return_intermediate_steps=True` parameter. This lets you collect all intermediate steps without relying on special callbacks.
|
||||
|
||||
For a deeper dive into the implementation and use of Trajectory Evaluators, refer to the sections below.

# Productionization
|
||||
|
||||
After you've developed a prototype of your language model application, the next step is to prepare it for production.
|
||||
This section contains guides around best practices for getting and keeping your application production-ready,
|
||||
ensuring it's ready for real-world use.

# Privacy & Safety
|
||||
|
||||
One of the key concerns with using LLMs is that they may misuse private data or generate harmful or unethical text. This is an area of active research in the field. Here we present some built-in chains inspired by this research, which are intended to make the outputs of LLMs safer.
|
||||
|
||||
- [Amazon Comprehend moderation chain](/docs/guides/productionization/safety/amazon_comprehend_chain): Use [Amazon Comprehend](https://aws.amazon.com/comprehend/) to detect and handle Personally Identifiable Information (PII) and toxicity.
|
||||
- [Constitutional chain](/docs/guides/productionization/safety/constitutional_chain): Prompt the model with a set of principles which should guide the model behavior.
|
||||
- [Hugging Face prompt injection identification](/docs/guides/productionization/safety/hugging_face_prompt_injection): Detect and handle prompt injection attacks.
|
||||
- [Layerup Security](/docs/guides/productionization/safety/layerup_security): Easily mask PII & sensitive data, detect and mitigate 10+ LLM-based threat vectors, including PII & sensitive data, prompt injection, hallucination, abuse, and more.
|
||||
- [Logical Fallacy chain](/docs/guides/productionization/safety/logical_fallacy_chain): Checks the model output against logical fallacies to correct any deviation.
|
||||
- [Moderation chain](/docs/guides/productionization/safety/moderation): Check if any output text is harmful and flag it.
|
||||
- [Presidio data anonymization](/docs/guides/productionization/safety/presidio_data_anonymization): Helps to ensure sensitive data is properly managed and governed.

# Layerup Security
|
||||
|
||||
The [Layerup Security](https://uselayerup.com) integration allows you to secure your calls to any LangChain LLM, LLM chain or LLM agent. The LLM object wraps around any existing LLM object, allowing for a secure layer between your users and your LLMs.
|
||||
|
||||
While the Layerup Security object is designed as an LLM, it is not actually an LLM itself, it simply wraps around an LLM, allowing it to adapt the same functionality as the underlying LLM.
|
||||
|
||||
## Setup
|
||||
First, you'll need a Layerup Security account from the Layerup [website](https://uselayerup.com).
|
||||
|
||||
Next, create a project via the [dashboard](https://dashboard.uselayerup.com), and copy your API key. We recommend putting your API key in your project's environment.
|
||||
|
||||
Install the Layerup Security SDK:
|
||||
```bash
|
||||
pip install LayerupSecurity
|
||||
```
|
||||
|
||||
And install LangChain Community:
|
||||
```bash
|
||||
pip install langchain-community
|
||||
```
|
||||
|
||||
And now you're ready to start protecting your LLM calls with Layerup Security!
|
||||
|
||||
```python
|
||||
from langchain_community.llms.layerup_security import LayerupSecurity
|
||||

# Logical Fallacy chain
|
||||
|
||||
This example shows how to remove logical fallacies from model output.
|
||||
|
||||
## Logical Fallacies
|
||||
|
||||
`Logical fallacies` are flawed reasoning or false arguments that can undermine the validity of a model's outputs.
|
||||
|
||||
Examples include circular reasoning, false
|
||||
dichotomies, ad hominem attacks, etc. Machine learning models are optimized to perform well on specific metrics like accuracy, perplexity, or loss. However,
|
||||
optimizing for metrics alone does not guarantee logically sound reasoning.
|
||||
|
||||
Language models can learn to exploit flaws in reasoning to generate plausible-sounding but logically invalid arguments. When models rely on fallacies, their outputs become unreliable and untrustworthy, even if they achieve high scores on metrics. Users cannot depend on such outputs. Propagating logical fallacies can spread misinformation, confuse users, and lead to harmful real-world consequences when models are deployed in products or services.
|
||||
|
||||
Monitoring and testing specifically for logical flaws is challenging unlike other quality issues. It requires reasoning about arguments rather than pattern matching.
|
||||
|
||||
Therefore, it is crucial that model developers proactively address logical fallacies after optimizing metrics. Specialized techniques like causal modeling, robustness testing, and bias mitigation can help avoid flawed reasoning. Overall, allowing logical flaws to persist makes models less safe and ethical. Eliminating fallacies ensures model outputs remain logically valid and aligned with human reasoning. This maintains user trust and mitigates risks.
|
||||
|
||||
|
||||
## Example
|
||||
|

"Multi-language support in data pseudonymization is essential due to differences in language structures and cultural contexts. Different languages may have varying formats for personal identifiers. For example, the structure of names, locations and dates can differ greatly between languages and regions. Furthermore, non-alphanumeric characters, accents, and the direction of writing can impact pseudonymization processes. Without multi-language support, data could remain identifiable or be misinterpreted, compromising data privacy and accuracy. Hence, it enables effective and precise pseudonymization suited for global operations.\n",

We can improve this by adding a new recognizer to the anonymizer, which will treat time separately from the date.\n",

"\n",
|

"We have already written about the importance of anonymizing sensitive data in the previous section. **Reversible Anonymization** is an equally essential technology while sharing information with language models, as it balances data protection with data usability. This technique involves masking sensitive personally identifiable information (PII), yet it can be reversed and original data can be restored when authorized users need it. Its main advantage lies in the fact that while it conceals individual identities to prevent misuse, it also allows the concealed data to be accurately unmasked should it be necessary for legal or compliance purposes. \n",
|
||||
"\n",
|
||||
"## Overview\n",
|
||||
"\n",
|
||||
"We implemented the `PresidioReversibleAnonymizer`, which consists of two parts:\n",
|
||||
"\n",
|
||||
"1. anonymization - it works the same way as `PresidioAnonymizer`, plus the object itself stores a mapping of made-up values to original ones, for example:\n",
|
||||
"```\n",
|
||||
" {\n",
|
||||
" \"PERSON\": {\n",
|
||||
" \"<anonymized>\": \"<original>\",\n",
|
||||
" \"John Doe\": \"Slim Shady\"\n",
|
||||
" },\n",
|
||||
" \"PHONE_NUMBER\": {\n",
|
||||
" \"111-111-1111\": \"555-555-5555\"\n",
|
||||
" }\n",
|
||||
" ...\n",
|
||||
" }\n",
|
||||
"```\n",
|
||||
"\n",
|
||||
"2. deanonymization - using the mapping described above, it matches fake data with original data and then substitutes it.\n",
|
||||
"\n",
|
||||
"Between anonymization and deanonymization user can perform different operations, for example, passing the output to LLM.\n",
