# Chat model integrations

> Integrate with chat models using LangChain Python.

[Chat models](/oss/python/langchain/models) are language models that use a sequence of [messages](/oss/python/langchain/messages) as inputs and return messages as outputs <Tooltip tip="Older models that do not follow the chat model interface and instead use an interface that takes a string as input and returns a string as output. These models typically do not include the prefix 'Chat' in their name or include 'LLM' as a suffix.">(as opposed to traditional, plaintext LLMs)</Tooltip>.

## Featured models

<Info>
  **While these LangChain classes support the indicated advanced feature**, you may need to refer to provider-specific documentation to learn which hosted models or backends support the feature.

## Routers & proxies

Routers and proxies give you access to models from multiple providers through a single API and credential. They can simplify billing, let you switch between models without changing integrations, and offer features like automatic fallbacks.

| Provider                                            | Integration                                                  | Description                                                                                               |
| --------------------------------------------------- | ------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------- |
| [Agentic SpendGuard](https://agenticspendguard.dev) | [`SpendGuardChatModel`](https://agenticspendguard.dev)       | Runtime budget gate that refuses LLM calls which would exceed spend limits before they reach the provider |
| [Alephant AI](https://alephant.io/)                 | [`ChatAlephantAI`](https://alephant.io/)                     | AI gateway for cost control, bring-your-own-key routing, and access to models across multiple providers   |
| [OpenRouter](https://openrouter.ai/)                | [`ChatOpenRouter`](/oss/python/integrations/chat/openrouter) | Unified access to models from OpenAI, Anthropic, Google, Meta, and more                                   |
| [LiteLLM](https://www.litellm.ai/)                  | [`ChatLiteLLMRouter`](/oss/python/integrations/chat/litellm) | Unified interface for OpenAI, Anthropic, Azure, Hugging Face, and more with routing and fallbacks         |

## Chat Completions API

Certain model providers offer endpoints that are compatible with OpenAI's [Chat Completions API](https://platform.openai.com/docs/api-reference/chat). In such cases, you can use [`ChatOpenAI`](/oss/python/integrations/chat/openai) with a custom `base_url` to connect to these endpoints for basic chat functionality.

<Warning>
  `ChatOpenAI` targets [official OpenAI API specifications](https://github.com/openai/openai-openapi) only. Non-standard response fields from third-party providers (e.g., `reasoning_content`, `reasoning`, `reasoning_details`) **are not extracted or preserved**. Use a provider-specific package when you need access to non-standard features.

  For instance, OpenRouter has a dedicated LangChain integration. See the [`ChatOpenRouter` guide](/oss/python/integrations/chat/openrouter) for setup and usage.
