--- title: GoogleGenerativeAIStream description: Learn to use GoogleGenerativeAIStream helper function in your application. --- # `GoogleGenerativeAIStream` GoogleGenerativeAIStream has been removed in AI SDK 4.0. GoogleGenerativeAIStream is part of the legacy Google Generative AI integration. It is not compatible with the AI SDK 3.1 functions. It is recommended to use the [AI SDK Google Generative AI Provider](/providers/ai-sdk-providers/google-generative-ai) instead. The GoogleGenerativeAIStream function is a utility that transforms the output from Google's Generative AI SDK into a ReadableStream. It uses AIStream under the hood, applying a specific parser for the Google's response data structure. This works with the official Generative AI SDK, and it's supported in both Node.js, Edge Runtime, and browser environments. ## Import ### React ## API Signature ### Parameters }', description: 'The response object returned by the Google Generative AI API.', }, { name: 'callbacks', type: 'AIStreamCallbacksAndOptions', isOptional: true, description: 'An object containing callback functions to handle the start, each token, and completion of the AI response.
