What is Terminal-Bench 2.1 (Claude Code)?

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.

What does it test?

Terminal-Bench 2.1 (Claude Code) 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

How to read the score

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