Google ships Gemini 3.8 Flash and a gated Flash Cyber twin

Google's Gemini 3.8 Flash, its third Flash model inside six weeks, keeps 3.7 Flash's $0.75/$3.75 intro pricing while a Cyber variant ships only to vetted defenders.

Key points

• Model ID gemini-3.8-flash. Developers get it through the Gemini API (AI Studio, Android Studio), Antigravity and Stitch; enterprises via Gemini Enterprise; Google AI Pro and Ultra subscribers in the Gemini app, AI Mode in Search and Gemini in Sheets.
• Pricing: $0.75 input / $3.75 output per 1M tokens, the same intro rate as 3.7 Flash, valid through Dec 31, 2026; from Jan 1, 2027 it doubles to $1.50 / $7.50.
• Context: 1M-token input and a 64K output cap, taking text, images, audio, video and PDFs (per VentureBeat's report; Google's post omits window sizes). Neither page mentions open weights; access runs through Google's hosted API and products.
• Google's own numbers: 54.9% on HLE-Verified; ahead of most larger frontier models on DeepSWE v1.1; beats 3.7 Flash on Harvey's Legal Agent Benchmark and on Vals Finance Agent V2.
• Change vs 3.7: Google says 3.8 spends more reasoning steps and tool calls on hard tasks, so it can burn more tokens at high effort; 3.7 Flash stays supported for cheap runs.
• Flash Cyber, per Google: 47.2% pass@1 on CWE-Bench against 47.8% for an unnamed leading frontier model, and above 70% on an internal vulnerability-hunting test covering 20 programming languages; access only via the Fairwind Program.

Why it matters

For a small studio on the Gemini API this is a same-price swap from 3.7 Flash, with Google claiming better agentic coding and VentureBeat reporting that Arena.ai ranked it No. 14 on Agent Arena, against No. 32 for 3.7. Two catches: the model may spend more tokens at higher effort levels, so budget for long agent loops, and the intro price doubles on January 1, 2027. Flash Cyber is not a checkbox in AI Studio; it goes through the Fairwind Program to governments, infrastructure operators and software maintainers.
