## Notes

Public preview in the Live API/AI Studio from 2026-06-09; Meet private preview; Google Translate on Android/iOS (incl. headphone 'listening mode'). Outputs SynthID-watermarked. No function calling, thinking or caching. Model card (read 2026-09-29): https://deepmind.google/models/model-cards/gemini-3-5-audio/ - covers Gemini 3.5 Live Translate, Transcribe and Transcribe Live (card dated 2026-08-26); no numeric evals in the card itself; knowledge cutoff January 2025; did not reach any Tracked or Critical Capability Levels under the Frontier Safety Framework. Card-listed Live Translate limitations: inconsistent voices, language detection struggles with non-native accents and rapid switching, imperfect background-noise handling, occasional audio artifacts. OpenAI's rival gpt-realtime-translate launched a month earlier (2026-05-07).
