Gemini 2.5 Pro

Gemini 2.5 Pro is a multimodal large language model developed by Google DeepMind. Initially released as an experimental version in March 2025, it is distinguished by its thinking architecture, which incorporates native reasoning capabilities for complex task processing and multi-step analysis. This design makes the model particularly effective for technical domains like mathematics, advanced coding, and scientific research. It features a standard context window of 1 million tokens, with support for the ingestion of extensive datasets including hour-long videos and large-scale code repositories. As a natively multimodal system, Gemini 2.5 Pro processes and reasons across text, audio, images, and video within a single model architecture. It also introduces a configurable thinking mode that allows users to adjust the reasoning budget to balance processing depth with response speed.
