Gemini 1.5 flash retirement date

I’d like to know where I can find information regarding retirement dates for Gemini 1.5 Flash models for the Gemini Developer API.
I can’t seem to find this information anywhere in the official Gemini API documentation:

Edit: This was prompted by the announcement that Gemini 1.5 will be retired on Vertex AI Gemini API

You’re right—model lifecycle information isn’t currently available in the Gemini API docs. However, you can find the official retirement dates for Gemini 1.5 models, including Flash, in Model versions and lifecycle  |  Generative AI on Vertex AI  |  Google Cloud.

For example, Gemini 1.5 Flash 002 is scheduled for deprecation on September 24, 2025. If you’re using the alias gemini-1.5-flash in your code, it currently points to the latest stable model (002), so it will be affected on that date.
