Core Capabilities

Superior Reasoning and Response: Equipped with frontier-level logical reasoning capabilities, it can efficiently handle complex multi-step tasks. Compared to previous generations, it demonstrates significant improvements in programming consistency, instruction adherence, and code logic integration, greatly reducing user friction.

Outstanding Computer Usage Skills: It performs exceptionally well in authoritative evaluations such as OSWorld, enabling it to interact with computers like a human—clicking the mouse and typing on the keyboard—and achieving cross-software and cross-browser automation. This effectively addresses business scenarios that traditional APIs cannot reach.

Ultra-long Context Planning: Supporting a context window of up to 1 million tokens, it boasts powerful long-distance logical reasoning capabilities, allowing it to process entire large codebases, multiple lengthy contracts, or dozens of research papers—all in one go.

Enterprise-Ready for Development: It has optimized output stability and instruction-following quality, effectively reducing issues such as model “laziness” or over-engineering. It is not only suitable for developing AI agents with frequent interactions but also supports the design of complex engineering architectures and bug fixes.
