What moved

DeepMind published “Introducing Gemini 3.8 Live and 3.8 Live Extended Thinking” on 2026-09-15. DeepMind issued this as an official post on 2026-09-15. The desk files the title and summary from the allow-listed feed, not a rewrite of claims the source did not make. No second outlet is added, and no launch is invented. The primary source stays on this page so the original wording remains the claim of record.

Why it matters

This brief exists so the official DeepMind claim on 2026-09-15 has a dated, public file. The desk does not add a second source or a launch the publisher did not post.
