AgentHarm Verified (Meta)
Muse Spark 1.1 3.40% Only in system cards Agents receive 108 malicious AgentHarm tasks kept after human review, plus a benign set. Reports average harm score and false refusal rate.
Meta-filtered subset of the public AgentHarm benchmark with a policy-auditing judge.
- Level
- Expert Specialists with years of training, often over hours of work
- Scored
- Graded by a model A language model scores each response, usually against a rubric.
- Answers
- Agent task Many steps in a terminal, browser, desktop, app, game or robot.
Muse Spark 1.1 leads with 3.40%
Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

Scores over time
All the scores we have, one dot each, so a model tested at several settings appears more than once.
Labs report it only in system cards
We read the headline results of 479 launch posts from 51 labs, and none of them list this benchmark. Some system cards do, below.
One system card reports it
Besides launch posts, we read the system cards, model cards and technical reports labs publish with a release. They report far more, including safety and frontier-risk tests.
