Terminal-Bench 2.1
A command-line agent benchmark for completing terminal tasks in reproducible task environments.
What this benchmark measures
A command-line agent benchmark for completing terminal tasks in reproducible task environments.
Rows on this page are sourced from public benchmark artifacts, leaderboard exports, or source-linked model reports. Each row keeps benchmark version, source model name, and available run details attached to the score.
The metric shown here is task success. It should be interpreted within Terminal-Bench 2.1, not compared as part of a site-wide ranking.
What to be careful about
A score cell must show agent scaffold and harness, not just model.
Frequently asked
What is Terminal-Bench 2.1?
A command-line agent benchmark for completing terminal tasks in reproducible task environments. It is a agents benchmark measured by task success.
What does task success mean on Terminal-Bench 2.1?
Terminal-Bench 2.1 reports task success (%); higher is better. Scores are shown only within Terminal-Bench 2.1 and are never averaged with other benchmarks.
What is the top reported Terminal-Bench 2.1 score?
GPT-5.6 Sol Ultra has the top reported score on Terminal-Bench 2.1: 91.9% (task success).
Why do Terminal-Bench 2.1 scores differ across runs?
Harness, scaffold, reasoning effort, and prompt setup change results, so two runs of the same model can differ. evals.report keeps each score with its run context so the differences stay visible.
Does evals.report rank models across benchmarks?
No. Terminal-Bench 2.1 scores are shown within their own metric; evals.report never combines benchmarks into a composite ranking or a single "best model".
