What is Gemini 3.5 Pro?

Gemini 3.5 Pro is Google DeepMind's announced next Pro-tier Gemini model. Google officially confirmed it at Google I/O on May 19, 2026, saying it was already in internal use and would roll out the following month, targeting a 2M-token context window and Deep Think reasoning. It has not yet been broadly released; reports indicate it remains in a limited Vertex AI preview for select enterprise customers and has not reached the consumer Gemini app or AI Studio.

Google's official target is a 2M-token context window and Deep Think reasoning, with general availability originally expected in June 2026. Leaked internal benchmarks reportedly show it outperforming Claude Fable 5 with significant zero-shot improvements, and early testers claim strong frontend/UI generation ability beating Fable 5 and GLM 5.2; some observers express frustration that the launch has slipped while Google ships other models.
