Archive entry: this covers an event from September 2, 2026, and we published it on November 8, 2026. The details come from sources dated at the time and may have changed since.

On September 2, 2026, Google made Gemini 3.8 Flash generally available in the Gemini API and launched a limited-access 3.8 Flash Cyber variant alongside it, according to its announcement of Gemini 3.8 Flash and 3.8 Flash Cyber. Google called Gemini 3.8 Flash its best reasoning and coding model yet and its third Flash release in six weeks.

What changed

  • Gemini 3.8 Flash was priced the same as Gemini 3.7 Flash, at $0.75 per 1M input tokens and $3.75 per 1M output tokens.
  • It scored 54.9% on HLE-Verified and outperformed Gemini 3.7 Flash on Vals Finance Agent V2 and Harvey's Legal Agent Benchmark.
  • Google said it might use more tokens at higher effort levels, so developers could pick lower effort levels or stay on Gemini 3.7 Flash, which remained fully supported for efficiency-first workloads.
  • Google reported a significant leap in prompt-injection robustness as measured by Gray Swan, and the model shipped with CBRN and cyber-offense misuse safeguards under Google's Frontier Safety Framework.
  • It was available in Google Antigravity, Google AI Studio, Android Studio, Stitch and Gemini Enterprise, and Google AI Pro and Ultra subscribers got it in the Gemini app, AI Mode in Search and Gemini in Google Sheets.

What it means for people building with AI

For people building with Gemini, the Flash tier became more capable without a price increase, with Google noting that higher effort levels may use more tokens. Google later made 3.8 Flash the target that retired Gemini models route to.
