Maintain context over long-running tasks and continue making progress across research, repository operations, and application building.
Perform strongly on knowledge-work and legal-work evaluations such as GDPVal-AA v2, AA-Briefcase, and Harvey LAB.
Training covers general coding, knowledge work, kernel optimization, web development, CAD, and other agent environments.
The company says more self-testing and verification behavior appears in long trajectories.

The company notes that competitor scores come from system cards or public leaderboards published by their respective developers, rather than from four models rerun in the same experimental environment. The table is therefore suitable for directional judgment, but should not be treated as a strict head-to-head experimental conclusion. In particular, the Terminal-Bench version, reasoning level, and execution harness all affect the results.
