Terminal-Bench 2.1 (Terminus-2)

Terminal-Bench tests whether a model can operate a computer through a terminal as an agent: it gets a Linux container and has to solve hands-on tasks (installing packages, inspecting files, writing scripts) purely via shell commands within a time limit. The score is the share of tasks completed successfully, averaged over several runs.

Terminal-Bench 2.1 (Terminus-2) measures how well a model works as an autonomous coding agent. In detail, it checks:

• planning and executing multi-step shell workflows
• installing, configuring and debugging software in a container
• handling timeouts and failing commands
• finishing the task within the given compute and time budget

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.
