Deep reasoning across code, math, and documents

Gemini 2.5 Pro is a thinking model developed by Google DeepMind, designed to reason through complex problems rather than simply predict outputs. It is built to analyze information, draw logical conclusions, and incorporate contextual nuance across tasks in code, mathematics, and STEM. The model supports native multimodality, meaning it can process text, images, audio, video, and code repositories within a single context.

The model features a 1,048,576-token context window, making it suited for tasks that require processing large documents, entire codebases, or extended conversations. It scored 63.8% on the SWE-Bench Verified coding evaluation and is available through the Gemini API and Google AI Studio. It is best suited for developers and researchers working on complex reasoning tasks, long-document analysis, and advanced code generation.

What Gemini 2.5 Pro supports

Extended Context Window

Processes up to 1,048,576 tokens in a single context, enabling analysis of large documents, codebases, or long conversation histories without truncation.

Structured Reasoning

Uses a thinking approach to work through multi-step problems, drawing logical conclusions before producing a final response rather than generating output directly.

Multimodal Input

Accepts text, images, audio, video, and code as input within the same request, allowing mixed-media tasks to be handled in a single call.

Tool Use

Supports function calling and external tool integration, allowing the model to invoke defined tools and return structured results as part of a response.

Code Generation

Generates and debugs code across languages, achieving a 63.8% score on the SWE-Bench Verified benchmark for real-world software engineering tasks.

Math and STEM Analysis

Handles complex mathematical reasoning and science problems, with benchmark performance cited across math and science evaluation suites.
