Gemini 3.8 Live Extended Thinking
0out of 100same as last month
Summary
Gemini 3.8 Live Extended Thinking targets complex, multi-step voice interactions that need background reasoning. Google describes it as an audio-to-audio model that reasons and runs asynchronous tool calls while streaming continuous audio. It accepts text, images, audio, and video and returns text and audio. The conversation can stay live while the model works through a harder request.
Reasoning effort can be set to low, medium, or high, and the API documents 131,072 input tokens with 65,536 output tokens. Compared with Gemini 3.8 Live, this variant keeps asynchronous function calls and their reasoning signals available while the audio response continues.

- Methodology
- Vendor-reported result. Google DeepMind's official performance chart labels this result as the Sierra τ³-Banking leaderboard and names the exact model variant Gemini 3.8 Live Extended Thinking. The chart caption does not state reasoning effort, model/serving revision, task setup, sample count, or confidence interval. No Sierra evaluator row was located in this pass; this is retained solely as the official vendor-published report of its external benchmark result.
- Context
- This is Google DeepMind's vendor-reported chart value, not a direct Sierra leaderboard capture. Reasoning effort, evaluation setup, N, CI, and serving revision are not published in the page. Do not equate τ³-Banking with Artificial Analysis τ-Voice.

- Methodology
- Independent evaluation. Cekura's separate row is Gemini 3.8 Live Extended Thinking, with thinking level high. The benchmark uses the same 82 scenarios for every model, each run three times, for 246 live calls per model. Reliability is the pass^3 scenario rate; the page reports 52.4%.
- Context
- The API serving revision is not pinned and the page does not publish a confidence interval. Do not confuse scenario N=82 with 246 calls.

- Methodology
- Independent evaluation. The exact leaderboard row is Gemini 3.8 Live Ext. Thinking. The source reports the end-of-turn score from Sesame TurnBench's published scorer, averaged over six line conditions and a 25-script private leaderboard set. It reports 36 calls per model per condition; all models heard the same recorded calls, streamed from US East with provider-default turn detection.
- Context
- The private benchmark set cannot be rerun externally. The page says its 95% range overlaps with several models but gives no exact interval for this row; no CI or serving revision is recorded.

- Methodology
- Independent evaluation. The exact MIVAS model profile is Gemini 3.8 Live Extended Thinking with model ID gemini-3.8-live-extended-thinking, HIGH thinking level and native audio input/output. The Bluejay LiveKit multi-agent voice-agent harness was evaluated in September 2026 on healthcare, legal and customer-support suites, 1,080 scored conversations in total with five scored trials per task. The source's direct Cross-industry row reports pass@1. No metric-specific denominator is published.
- Context
- This is a multi-agent system result, not an isolated model score. The public profile identifies the model and HIGH effort, but no immutable result-code revision or metric-specific N/CI is published.

- Community-reported result. Cekura speech-to-speech whole-agent workflow comparison. Exact model ID gemini-3.8-live-extended-thinking (displayed as Gemini 3.8 Live Extended Thinking); thinking level high; voice Charon; service turn detection; audio 16 kHz.
