langchain-xai

What it is and what it does

langchain-xai is a LangChain integration package that bridges xAI's language models to the LangChain ecosystem. It provides a ChatXAI class and related components that allow developers to use xAI models within LangChain applications, enabling access to xAI's APIs through the standard LangChain interface.

The package depends on langchain-core for base abstractions, langchain-openai for compatible model patterns, and standard HTTP libraries (aiohttp, requests) for API communication. It targets modern Python versions (3.10 through 3.14) and is actively maintained by the LangChain team. Use it when you want to incorporate xAI models into a LangChain application without writing custom API integration code.

Use it for:

• Build a chatbot or conversational agent using xAI models within a LangChain application.
• Chain xAI model calls with other LangChain tools, retrievers, or agents in a multi-step workflow.
• Migrate or extend an existing LangChain application to include xAI as an alternative model provider.
• Prototype or experiment with xAI models alongside other LLM providers in a unified LangChain interface.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Connects xAI's language models to LangChain applications through their APIs, enabling integration of xAI models into LangChain workflows.

Yes, if you are building a LangChain application and want to use xAI models. The package is actively maintained, has no known vulnerabilities, low install friction, and permissive licensing. Install it when you have an xAI API key and need xAI model access within LangChain; skip it if you do not plan to use xAI models or are not using LangChain.

Install

langchain-xai on PyPI

pip install langchain-xai

uv add langchain-xai

poetry add langchain-xai

Installing langchain-xai

Before you install

Low install friction with a pure Python wheel. Actively maintained as of 24 days ago with a recent release on 2026-07-21. Depends on langchain-core, langchain-openai, aiohttp, and requests—all stable, widely-used libraries.

License in practice

MIT license permits free use, modification, and distribution with minimal restrictions, making it suitable for both open-source and commercial projects.

Quickstart

pip install langchain-xai

from langchain_xai import ChatXAI

chat = ChatXAI(api_key="your-xai-api-key")
response = chat.invoke("Hello")

Requires a valid xAI API key from https://console.x.ai and Python >= 3.10.0, < 4.0.0.

Verify before relying

• Whether xAI model names and capabilities are documented in the package or require external reference.
• Whether the package supports streaming, tool use, or other advanced LangChain features.
• Cost and rate-limit behavior of xAI API calls through this integration.
