Overview
- Google publicly launched Gemini 3.8 Flash and Gemini 3.8 Flash Cyber on September 2, 2026, with the Cyber variant limited to vetted partners through its Fairwind program and the general Flash model available across Google developer and consumer channels.
- Gemini 3.8 Flash is built as a workhorse for long-horizon software engineering, multimodal agentic workflows, and multi-step reasoning by taking extra internal reasoning steps and making iterative tool calls to improve correctness.
- Google kept introductory per-token pricing at $0.75 per million input tokens and $3.75 per million output tokens through December 31, 2026, and warned that the model’s higher-effort mode can use more tokens and therefore raise real bills for complex tasks.
- Google and its partners report strong internal results for 3.8 Flash Cyber, including Chrome Security saying it produced 2.6 times more correct patches, Wiz reporting 7.5–9.7% higher recall on an internal test, and Google Cloud finding a critical vulnerability in under two hours, though most performance claims come from Google and allied partners.
- The launch is the third Flash release in roughly six weeks as Google shifts to a rapid, continuous‑deployment cadence to win production agent and coding workloads while delaying a larger Pro flagship and joining rivals in gating powerful cyber tooling.
