CohereStream
CohereStream has been removed in AI SDK 4.0.
CohereStream is part of the legacy Cohere integration. It is not compatible with the AI SDK 3.1 functions.
The CohereStream function is a utility that transforms the output from Cohere's API into a ReadableStream. It uses AIStream under the hood, applying a specific parser for the Cohere's response data structure. This works with the official Cohere API, and it's supported in both Node.js, the Edge Runtime, and browser environments.
