Voice benchmark evidence
Gemini 3.8 Audio model evaluation is an owner-defined voice evaluation. Its result stays separate from BenchLM's weighted text-model ranking.
Lineage
The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Gemini 3.8 Live Extended Thinking, but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.
Gemini 3.8 Live Extended Thinking is a proprietary model with a 128K context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
Available as the stable `gemini-3.8-live-extended-thinking` Live API model, with Google AI Studio, Gemini app, Vertex AI, and Google Workspace access listed on the model card. The launch announcement names Docs Live, Gmail Live and Keep Live in Workspace and the Daily Brief in the Gemini app, and a private preview in Gemini Enterprise. All audio output is watermarked with SynthID.
Google’s September 15 Gemini 3.8 Audio card describes a separate Live Extended Thinking variant with 128K input context, background reasoning, and audio and text output. High-effort voice evaluations stay display-only and are not assigned to the default Live row.
Gemini 3.8 Live Extended Thinking sits in the Gemini 3.8 Live family with Gemini 3.8 Live. Speech or voice evidence appears above; text-model benchmark coverage remains empty.

Questions
How does Gemini 3.8 Live Extended Thinking perform overall in AI benchmarks?
Gemini 3.8 Live Extended Thinking has published speech or voice results in Gemini 3.8 Audio model evaluation. Those results remain separate from the weighted text-model ranking, so this profile does not assign a BenchLM score or overall rank. Use the linked evaluation's metric and run conditions to compare speech systems.
Which sibling models are related to Gemini 3.8 Live Extended Thinking?
Gemini 3.8 Live Extended Thinking belongs to the Gemini 3.8 Live family. Related tracked variants include Gemini 3.8 Live. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does Gemini 3.8 Live Extended Thinking have full benchmark coverage on BenchLM?
No. Gemini 3.8 Live Extended Thinking's speech or voice results appear in Gemini 3.8 Audio model evaluation, but it has no published text-model benchmark rows. The voice evaluation does not fill the text-model coverage slots or produce an overall rank. Missing text coverage is not treated as a zero score.
What is the context window size of Gemini 3.8 Live Extended Thinking?
Gemini 3.8 Live Extended Thinking has a documented context window of 128K. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
