langchain-google-vertexai This package contains the LangChain integrations for Google Cloud generative models. Installation pip install -U langchain-google-vertexai Chat Models ChatVertexAI class exposes models such as gemini-pro and chat-bison. To use, you should have Google Cloud project with APIs enabled, and configured credentials. Initialize the model as: from langchain_google_vertexai import ChatVertexAI llm = ChatVertexAI(model_name="gemini-pro") llm.invoke("Sing a ballad of LangChain.") You can use other models, e.g. chat-bison: from langchain_google_vertexai import ChatVertexAI llm = ChatVertexAI(model_name="chat-bison", temperature=0.3) llm.invoke("Sing a ballad of LangChain.") Multimodal inputs Gemini vision model supports image inputs when providing a single chat message. Example: from langchain_core.messages import HumanMessage from langchain_google_vertexai import ChatVertexAI llm = ChatVertexAI(model_name="gemini-pro-vision") message = HumanMessage( c

LangChain Graph Retriever LangChain Graph Retriever is a Python library that supports traversing a document graph on top of vector-based similarity search. It works seamlessly with LangChain's retriever framework and supports various graph traversal strategies for efficient document discovery. Features Vector Search: Perform similarity searches using vector embeddings. Graph Traversal: Apply traversal strategies such as breadth-first (Eager) or Maximal Marginal Relevance (MMR) to explore document relationships. Customizable Strategies: Easily extend and configure traversal strategies to meet your specific use case. Multiple Adapters: Support for various vector stores, including AstraDB, Cassandra, Chroma, OpenSearch, and in-memory storage. Synchronous and Asynchronous Retrieval: Supports both sync and async workflows for flexibility in different applications. Installation Install the library via pip: pip install langchain-graph-retriever Getting Started Here is an example of how to

langchain-ibm This package provides the integration between LangChain and IBM watsonx.ai through the ibm-watsonx-ai SDK. Installation To use the langchain-ibm package, follow these installation steps: pip install langchain-ibm Usage Setting up To use IBM's models, you must have an IBM Cloud user API key. Here's how to obtain and set up your API key: Obtain an API Key: For more details on how to create and manage an API key, refer to IBM's documentation. Set the API Key as an Environment Variable: For security reasons, it's recommended to not hard-code your API key directly in your scripts. Instead, set it up as an environment variable. You can use the following code to prompt for the API key and set it as an environment variable: import os from getpass import getpass watsonx_api_key = getpass() os.environ["WATSONX_APIKEY"] = watsonx_api_key In alternative, you can set the environment variable in your terminal. Linux/macOS: Open your terminal and execute the following command: ex

langchain-mistralai This package contains the LangChain integrations for MistralAI through their mistralai SDK. Installation pip install -U langchain-mistralai Chat Models This package contains the ChatMistralAI class, which is the recommended way to interface with MistralAI models. To use, install the requirements, and configure your environment. export MISTRAL_API_KEY=your-api-key Then initialize from langchain_core.messages import HumanMessage from langchain_mistralai.chat_models import ChatMistralAI chat = ChatMistralAI(model="mistral-small") messages = [HumanMessage(content="say a brief hello")] chat.invoke(messages) ChatMistralAI also supports async and streaming functionality: await chat.ainvoke(messages) for chunk in chat.stream(messages): print(chunk.content, end="", flush=True) Embeddings With MistralAIEmbeddings, you can directly use the default model 'mistral-embed', or set a different one if available. Choose model embedding.mode
