Gemini 3.8 Flash
Released 2 Sep 2026 alongside a restricted Gemini 3.8 Flash Cyber variant — by Google's own count the third Flash release in six weeks, and further evidence that the Pro line has stalled: Gemini 3.1 Pro (19 Feb 2026) is still the current Pro model, and every release since has been Flash-tier. The headline number is speed. At 345.1 tokens per second it is the fastest model of the 199 Artificial Analysis measures, roughly five times the 68 tok/s median, while scoring 41 on the v4.3 Intelligence Index. The offset is a 30.49s time to first token, so the throughput only pays off on long generations. Pricing holds at the 3.7 Flash introductory rate of $0.75/$3.75 with a 90% cache discount — but note that this is introductory: from 1 Jan 2027 the rates double to $1.50 and $7.50, which is worth modelling now if you are sizing a 2027 budget. Google's own benchmark table has 3.8 Flash ahead of 3.7 Flash on every published row: DeepSWE v1.1 73.7% vs 65.3%, Terminal-bench 2.1 89.4% vs 85.8%, OSWorld-2.0 59.0% vs 50.6%, Vals Finance Agent v2 61.4% vs 59.0%, HLE-Verified 54.9% vs 53.6% — all first-party runs. Google attributes the gains to the model executing extra reasoning steps and calling tools iteratively, which also explains why Artificial Analysis flags it 'very verbose' at 170M output tokens against a 90M median. 1M context. The Cyber variant is gated behind the new Fairwind Programme for government authorities, critical infrastructure operators and software maintainers.
