Gemini 1.5 ProvsGemini 2.5 Pro

Gemini 1.5 Pro is Google DeepMind's flagship multimodal model featuring an industry-leading 1 million token context window, capable of processing entire codebases, books, or hours of video in a single prompt. It demonstrates exceptional performance on long-context reasoning tasks, multimodal understanding across text, images, audio, and video, and complex coding challenges. The massive context window opens entirely new use cases that were previously impossible with shorter-context models.

Gemini 2.5 Pro is Google DeepMind's most capable AI model, featuring an industry-leading 1 million token context window that can process entire books, codebases, or hours of video in a single request. Built with native multimodal capabilities, it understands text, images, audio, and video natively rather than through separate encoders. The model demonstrates exceptional performance on coding benchmarks, mathematical reasoning, and multi-step planning tasks. Its massive context window makes it uniquely suited for tasks involving large document analysis, repository-scale code understanding, and long video comprehension. Gemini 2.5 Pro also features built-in 'thinking' capabilities similar to reasoning models, allowing it to tackle complex problems with improved accuracy. Available through Google AI Studio and Vertex AI.
