Google DeepMind · 2025-05-20
Gemini 2.5 Flash Preview 05-20 is Google’s May 20, 2025 preview snapshot of its price-performance-optimized multimodal model, with adaptive thinking that developers can disable or control with a token budget. It improved reasoning, coding, long-context performance, and token efficiency over the 04-17 preview; Google later promoted the same 05-20 model unchanged as Gemini 2.5 Flash GA on June 17, 2025.
