Gemini Live API ~ websocket for text problems since latest updates

hi,

we have been successfully using Gemini live with 'gemini-live-2.5-flash-preview’ via wscat, mainly conversing in text. We used it mainly for low latency reasons (keeping the high quality).

However, since the last update (~5-7 days ago) Gemini Live is now focused on audio and video streaming and i am having trouble understanding which model / how to use it for regular text. We now have to roll back to ‘gemini-2.0-flash-exp‘ with noticeable decrease in quality.

Would someone know what happened and which model should we use? thanks!

Hi @oxford_command ,

The gemini-live-2.5-flash-preview model was shutdown on 9th December 2025. If your use-case is text-to-text along with low-latency, you can try gemini-2.5-flash. Since the Live API is focused on audio/video, you can try setting "response_modalities": ["TEXT"] in your config explicitly to maintain low-latency text performance without the audio focus.
