 ## `AIStream(res: Response, customParser: AIStreamParser => void, callbacks?:  AIStreamCallbacksAndOptions): ReadableStream` [#aistream]
 
-`AIStream` is a helper function for creating a readable stream for AI responses. This is based on the responses returned by `fetch` and serves as the basis for the [`OpenAIStream`](./openai-stream) and [`AnthropicStream`](./anthropic-stream). It allows you to handle AI response streams in a controlled and customized manner that will work with [`useChat`](./use-chat) and [`useCompletion`](./use-completion).

 `AIStream` will throw an error if `res` doesn't have a `2xx` status code. This is to ensure that the stream is only created for successful responses.

 ## `LangChainStream(callbacks?: AIStreamCallbacks): { stream: ReadableStream, handlers: LangChainCallbacks }` [#langchainstream]
 
-`LangChainStream` is a utility function designed to facilitate the integration of [LangChain](https://js.langchain.com/docs) - a framework for engineering prompts for AI language models - with UI components and data streaming to the client side. Returns a `stream` and bag of [LangChain](js.langchain.com/docs) `BaseCallbackHandlerMethodsClass` that automatically implement streaming in such a way that you can use [`useChat`](./use-chat) and [`useCompletion`](./use-completion).
