I am writing to seek urgent clarification regarding the upcoming deprecation and model migration, as we are less than two weeks away from the 2025-12-09 deadline.
- Model Identification & Deprecation
Currently, my production environment relies on gemini-2.5-flash-live-preview, which has been very stable.
The documentation states that gemini-live-2.5-flash-preview will be deprecated on Dec 9, 2025.
Question: Can you confirm if gemini-2.5-flash-live-preview is indeed the model being deprecated?
2. Stability Issues with the Replacement Model
I attempted to migrate to the recommended newer model: gemini-2.5-flash-native-audio-preview-09-2025.
However, I have encountered severe stability issues and regressions compared to the previous version, specifically regarding Function Calling and Instruction Following.
Specific Regressions Observed:
Infinite Tool Calling Loops: The native-audio model frequently gets stuck in a loop, repeatedly calling the same tool/function without processing the result or moving forward. The previous live-preview model handled this correctly.
Ignoring System Instructions: The model often disregards the prompt instructions during the session, which was not an issue with the older model.
The Dilemma
With the Dec 9th deprecation imminent, I am forced to choose between a deprecated model or an unstable one that breaks my application logic.
Is there a more stable version of the native-audio model available?
Will the life of gemini-2.5-flash-live-preview be extended until the regressions in the new model are fixed?
Thanks.
since gemini-2.5-flash-live-preview is stable as it is
