Gemini 2.5: context scaling and multimodality
Gemini 2.5 Pro reached preview on 25 March 2025 and general availability at the end of June, alongside the cheaper, faster Gemini 2.5 Flash. Two things separate it from Gemini 2.0: a one-million-token context window that behaves stably to at least 500k, and multimodality that has left the demo stage behind.
