Computer-use benchmark results

These are arena-wide results. Each model encounters a different mix of tasks and opponents. The direct matchup, when available, is reported separately.

How to read this benchmark

Ranking and win rates use eligible comparisons from the latest 20,000 judged arena battles. Completion, speed and estimated cost use the leaderboard’s non-synthetic arena runs. Recovery uses the latest 1,000 arena battles. Operator experiments are excluded. These windows measure different things and should not be pooled.

A human preference is not a verified success label. Provisional ratings and overlapping intervals do not establish a reliable winner.

Questions about these results

Is MiMo V2.6 Pro or Muse Spark 1.2 better for computer use?

There are no eligible head-to-head results for MiMo V2.6 Pro and Muse Spark 1.2 in the current ranking window. Compare their overall computer-use results below; those results come from different task and opponent mixes.

Does completion mean the task was verified?

No. Completion for MiMo V2.6 Pro and Muse Spark 1.2 records whether the agent reported finishing. Human preferences, task success and next-action recovery are different measurements.

How should I compare speed and cost?

Read speed and estimated cost alongside completion and human preference. An early failure can be fast. Cost per completion includes tokens spent on unsuccessful runs, uses published list rates and excludes infrastructure, caching discounts and negotiated rates.

How often are these comparison results updated?

Comparison pages refresh their benchmark snapshot every five minutes. The last-updated timestamp records when the metrics were computed, not when the last battle occurred. Model rank may move between snapshots.
