.ipynb .pdf How to use the async API for Agents Contents Serial vs. Concurrent Execution Using Tracing with Asynchronous Agents How to use the async API for Agents# LangChain provides async support for Agents by leveraging the asyncio library. Async methods are currently supported for the following Tools: SerpAPIWrapper and LLMMathChain. Async support for other agent tools are on the roadmap. For Tools that have a coroutine implemented (the two mentioned above), the AgentExecutor will await them directly. Otherwise, the AgentExecutor will call the Tool’s func via asyncio.get_event_loop().run_in_executor to avoid blocking the main runloop. You can use arun to call an AgentExecutor asynchronously. Serial vs. Concurrent Execution# In this example, we kick off agents to answer some questions serially vs. concurrently. You can see that concurrent execution significantly speeds this up. import asyncio import time from langchain.agents import initialize_agent, load_tools from langchain.agents import AgentType from langchain.llms import OpenAI from langchain.callbacks.stdout import StdOutCallbackHandler from langchain.callbacks.base import CallbackManager from langchain.callbacks.tracers import LangChainTracer from aiohttp import ClientSession questions = [ "Who won the US Open men's final in 2019?

.ipynb .pdf How to combine agents and vectorstores Contents Create the Vectorstore Create the Agent Use the Agent solely as a router Multi-Hop vectorstore reasoning How to combine agents and vectorstores# This notebook covers how to combine agents and vectorstores. The use case for this is that you’ve ingested your data into a vectorstore and want to interact with it in an agentic manner. The recommended method for doing so is to create a RetrievalQA and then use that as a tool in the overall agent. Let’s take a look at doing this below. You can do this with multiple different vectordbs, and use the agent as a way to route between them. There are two different ways of doing this - you can either let the agent use the vectorstores as normal tools, or you can set return_direct=True to really just use the agent as a router.

.rst .pdf Text Embedding Models Text Embedding Models# Note Conceptual Guide This documentation goes over how to use the Embedding class in LangChain. The Embedding class is a class designed for interfacing with embeddings. There are lots of Embedding providers (OpenAI, Cohere, Hugging Face, etc) - this class is designed to provide a standard interface for all of them. Embeddings create a vector representation of a piece of text. This is useful because it means we can think about text in the vector space, and do things like semantic search where we look for pieces of text that are most similar in the vector space. The base Embedding class in LangChain exposes two methods: embed_documents and embed_query. The largest difference is that these two methods have different interfaces: one works over multiple documents, while the other works over a single document. Besides this, another reason for having these as two separate methods is that some embedding providers have different embedding methods for documents (to be searched over) vs queries (the search query itself). The following integrations exist for text embeddings.

While chat models use language models under the hood, the interface they expose is a bit different. Rather than expose a “text in, text out” API, they expose an interface where “chat messages” are the inputs and outputs. Chat model APIs are fairly new, so we are still figuring out the correct abstractions. The following sections of documentation are provided: Getting Started: An overview of all the functionality the LangChain LLM class provides. How-To Guides: A collection of how-to guides.

The interface is based around messages rather than raw text. from langchain.chat_models import ChatOpenAI from langchain import PromptTemplate, LLMChain from langchain.prompts.chat import ( ChatPromptTemplate, SystemMessagePromptTemplate, AIMessagePromptTemplate, HumanMessagePromptTemplate, ) from langchain.schema import ( AIMessage, HumanMessage, SystemMessage ) chat = ChatOpenAI(temperature=0) You can get chat completions by passing one or more messages to the chat model. The response will be a message. The types of messages currently supported in LangChain are AIMessage, HumanMessage, SystemMessage, and ChatMessage – ChatMessage takes in an arbitrary role parameter. Most of the time, you’ll just be dealing with HumanMessage, AIMessage, and SystemMessage chat([HumanMessage(content="Translate this sentence from English to French. I love programming.")]) AIMessage(content="J'aime programmer.", additional_kwargs={}) OpenAI’s chat model supports multiple messages as input. See here for more information. Here is an example of sending a system and user message to the chat model: messages = [ SystemMessage(content="You are a helpful assistant that translates English to French."), HumanMessage(content="Translate this sentence from English to French. I love programming.") ] chat(messages) AIMessage(content="J'aime programmer.", additional_kwargs={}) You can go one step further and generate completions for multiple sets of messages using generate. This returns an LLMResult with an additional message parameter. batch_messages = [ [ SystemMessage(content="You are a helpful assistant that translates English to French."),
