Gemini 3 Flash Preview

Gemini 3 · Released 2025-12-17

Google's December 2025 speed tier. 1M context, $0.50/$3 per 1M tokens. Vals Index 49.31 (#9), SWE-bench Verified 78.0%. Pro-level reasoning at Flash pricing.

Default Gemini route when 3.5 Flash is overkill and 3.1 Pro is too expensive. Strong on agentic coding at mid-tier cost.
