Resolution criterion
Yes if Google or DeepMind announces availability (official blog, ai.google.dev release notes, or gemini.google) of a model whose commercial name begins with "Gemini 4". Variants numbered 3.x do not count.
Verified starting state
The most recent release is Gemini 3.8 Flash, on 2 September 2026. The entire 2026 series is 3.x: 3.1 Pro on 19 February, 3.5 Flash on 19 May, 3.6 Flash on 21 July, 3.7 Flash on 13 August. Google has not shipped a new "Pro" tier since February. GPT-6 Astra was released in early September 2026.
