Description:
With the recent migration from google_generative_ai
to firebase_ai
, we’ve encountered a significant limitation: it is no longer possible to set a custom Gemini API key.
In google_generative_ai
, developers could allow end users to input their own Gemini API key. This is essential for applications that:
- Are designed to be self-hosted or run without a dedicated backend.
- Let users manage their own token usage and quotas.
- Require flexibility in using personal Google Cloud accounts.
However, firebase_ai
acts as a proxy between the app and Gemini, abstracting away the API key and centralizing access through Firebase. This makes it impossible for the end user to configure their own key, breaking this usage pattern.
Problem:
google_generative_ai
has been officially deprecated.firebase_ai
does not allow setting a custom API key.- There is currently no official Google-maintained alternative that supports this use case.
Request:
We propose one of the following solutions:
- Add optional support for setting a custom Gemini API key in
firebase_ai
, bypassing the Firebase proxy when detected. - Maintain a minimal legacy version of
google_generative_ai
to support this use case. - Clearly document this limitation and suggest viable alternatives for developers who rely on this pattern.
Justification:
This change would allow developers to continue building flexible, decentralized applications without being forced to rely solely on Firebase infrastructure, and without breaking compatibility with existing workflows.
