Think Bigger with Gemini 2.5 Pro
The flagship of the Gemini 2.5 family with Deep Think parallel reasoning, 1M token context, best-in-class coding, and leading long-context understanding

The Thinking Partner for Your Hardest Problems
Gemini 2.5 Pro is Google's most intelligent model in the 2.5 series, designed for the work that requires genuine depth — complex coding projects, multi-hour research sessions, advanced data analysis, and problems where you need to reason carefully across many pieces of information at once. It combines a powerful base model with thinking capabilities that go deeper than any previous Gemini model, making it the right choice whenever you need an AI that can truly engage with a complex task rather than just produce a quick response. Available inside Chat Smith for the most demanding work.

Deep Think: Parallel Reasoning for Complex Problems
Gemini 2.5 Pro's most distinctive capability is Deep Think, an advanced reasoning mode that allows the model to consider multiple hypotheses simultaneously before settling on an answer. Rather than working through a problem linearly, Deep Think explores different potential solutions in parallel, evaluates them, and synthesizes the most promising paths into a comprehensive response. For complex mathematical problems, multi-step logical puzzles, nuanced research questions, or any task where exploring several angles before committing to an answer matters, Deep Think gives Gemini 2.5 Pro a qualitative edge over models that reason only in a single direction.

Best-in-Class Coding for Complex Projects
Gemini 2.5 Pro is Google's top model for software development. It excels at creating visually compelling web applications, writing complex agentic code, transforming and editing large codebases, and managing intricate multi-file projects where changes need to flow consistently through the whole system. It understands the architecture of complex systems, reasons about how different components interact, and produces code that is not only functional but well-structured and maintainable. For developers working on ambitious projects inside Chat Smith, Gemini 2.5 Pro is the most capable coding partner Google has to offer.

Leads on Video and Long-Context Understanding
With its 1 million token context window and state-of-the-art performance on long-context tasks, Gemini 2.5 Pro can process and reason across volumes of information that would overwhelm other models. It's particularly strong on video understanding — analyzing long video content, extracting key moments with timing, summarizing what happens across extended footage, and answering questions about specific parts of a video. Combined with its ability to handle long documents, extended codebases, and large multi-document research corpora, this makes it exceptional for tasks that require synthesizing a complete picture from many sources.

Built for Learning With LearnLM Integration
Gemini 2.5 Pro incorporates LearnLM, Google's educational AI research, making it the leading model for learning-oriented tasks. It explains concepts clearly across many levels of complexity, adapts its explanations to your background, asks clarifying questions to understand what you already know, and builds understanding progressively rather than just delivering information. Whether you're studying a new field, working through a difficult concept, or building educational applications, Gemini 2.5 Pro's pedagogical capabilities make it uniquely effective for deep learning outcomes.
