Editor's note
Recorded from Google's 15 Sep 2026 Live announcement (updated 17 Sep), the Gemini API model and pricing pages, and the DeepMind Gemini 3.8 Audio model card (128K context, 64K output, January 2025 cutoff). Google-reported Speech Agent Arena, EVA-Bench, and τ-Voice figures stay vendor-claimed — not ledger rows. No independent AA Intelligence Index or Vals Index row as of 18 Sep 2026.
