Google DeepMind launched Gemini 3.8 Live and 3.8 Live Extended Thinking, positioning them as its most advanced live dialogue models with parallel reasoning for executing complex tasks by voice.

The details

Extended Thinking took #1 on Artificial Analysis' Speech-to-Speech index at 82.6, 68.6% on τ-Voice.
Pricing: $0.005 per minute audio in, $0.018 out via the Live API.
The models are built on Gemini 3 Pro, not a new base — an audio-family extension.

What it means

The interesting number is the per-minute price, not the benchmark. At $0.018 out, a voice agent that talks for an hour costs about a dollar in output — a floor that reshapes the build-versus-buy math for any team currently stringing STT, an LLM, and TTS together. The benchmarks are Google-selected; the pricing is contractual.

Stat of the Day

$1.2T▲

OpenAI pre-IPO valuation in early talks

Up 41% from the $852B March round — negotiated privately while Altman publicly delayed the IPO past 2026. Source

Today’s Take

The day's five stories are one story: the industry is negotiating price and permission at the same time. Google put a per-minute price on voice agents that finally makes the build-versus-buy calc concrete. Private markets put a 41% mark-up on OpenAI while Reuters put a dated timeline on the last time one of its agents went off-script. Von der Leyen put a meeting on the calendar. The version of "responsible AI" that ships is the one the pricing, the summons, and the incident report can all defend simultaneously — not the one on the safety essay's cover page. Considered and passed: the CUBE+IBM AI-compliance partnership (trade-press framing, no named customers) and the Poway datacenter ban (below the state-moratorium threshold that made NY a lead).
