Stream HelpersAnthropicStream

AnthropicStream

AnthropicStream is part of the legacy Anthropic integration. It is not compatible with the AI SDK 3.1 functions. It is recommended to use the AI SDK Anthropic Provider instead.

It is a utility function that transforms the output from Anthropic's SDK into a ReadableStream. It uses AIStream under the hood, applying a specific parser for the Anthropic's response data structure.

import { AnthropicStream } from "ai"

Response
The response object returned by a call made by the Provider SDK.
