Tracked as: Gemini 4 Flash / Gemini 3.9 Flash

Estimated release

Nov 12, 2026

Mid Nov 2026

Details

Status: Not announced; Gemini 4 Argon (Sept 30) has no Flash variant yet
Current model: Gemini 3.8 Flash, 40.9 on the Intelligence Index, released Sep 2, 2026 ()
Projected score: About 42.9 (+2)
Typical cycle: About 35 days between releases

Google's Flash takes the number of the latest major model: 2.5 Pro (Mar 2025) then 2.5 Flash (Apr 2025), Gemini 3 Pro (Nov 18, 2025) then Gemini 3 Flash (Dec 17, 2025)
Flash went 3.5, 3.6, 3.7, 3.8 (May 19 to Sept 2) only because Pro stayed on 3.1; with Gemini 4 Argon out, a 3.9 Flash looks unlikely
Gemini 3 Flash came about four weeks after Gemini 3 Pro; Argon is still limited to trusted testers, so the date counts from its wider rollout (expected mid October)
Gemini 3.8 Flash (40.9) is Google's best generally available model; Gemini 4 Argon scores 52.6
