#1Gemini 3.5 Flash
Google unveiled Gemini 3.5 Flash at I/O 2026, its strongest agentic and coding model yet — 4x faster than competing frontier models on output tokens per second. It tops benchmarks like Terminal-Bench 2.1 (76.2%) and CharXiv Reasoning (84.2%), and is available immediately across the Gemini app, AI Mode in Search, and developer APIs. Gemini 3.5 Pro is already in internal use and expected to roll out next month.
