Gemini 2.5: Pushing the frontier with advanced reasoning, multimodality, long context, and next generation agentic capabilities

Abstract:

In this report, we introduce the Gemini 2.X model family: Gemini 2.5 Pro and Gemini 2.5 Flash, as well
as our earlier Gemini 2.0 Flash and Flash-Lite models. Gemini 2.5 Pro is our most capable model yet,
achieving SoTA performance on frontier coding and reasoning benchmarks. In addition to its incredible
coding and reasoning skills, Gemini 2.5 Pro is a thinking model that excels at multimodal understanding
and it is now able to process up to 3 hours of video content. Its unique combination of long context,
multimodal and reasoning capabilities can be combined to unlock new agentic workflows. Gemini 2.5
Flash provides excellent reasoning abilities at a fraction of the compute and latency requirements and
Gemini 2.0 Flash and Flash-Lite provide high performance at low latency and cost. Taken together, the
Gemini 2.X model generation spans the full Pareto frontier of model capability vs cost, allowing users to
explore the boundaries of what is possible with complex agentic problem solving.
