    Firebase AI Logic now supports Gemini Live API with native audio models while retiring other Live API options. Available models include Gemini Developer API, gemini-2.5-flash-native-audio-preview-12-2025, Vertex AI Gemini API, and gemini-live-2.5-flash-native-audio. Enables low latency real time voice and video with audio input and output.

    Firebase AI Logic

    For Gemini Live API implementations, make sure that your app uses one of the native audio models. All other Live API models are now retired. Here are the most currently available model names:

    • Gemini Developer API
      • gemini-2.5-flash-native-audio-preview-12-2025
        Even though this is a preview model, it's available on the "free tier" of the Gemini Developer API.
    • Vertex AI Gemini API
      • gemini-live-2.5-flash-native-audio
        When using the Vertex AI Gemini API, the Live API models are not supported in the global location.

    Note that the native audio models always require audio input (along with optional additional modalities of text or video input), and they always respond with audio output.

    You can use the Gemini Live API via Firebase AI Logic to build low-latency, real-time voice and video interactions, including adding text transcriptions of audio input and output.

    Firebase AI Logic

    Firebase AI Logic now offers server prompt templates. When using server prompt templates, you store your prompt, schema, and configurations server-side. Then in the request from your app, you only provide the template's ID. You can protect against exposing your prompt client-side, as well as easily update your prompt, schema, and configs without releasing a new app version.
