Built from 90K+ real-world agent sessions across 30 models, Arena’s Alignment Index measures three critical signals:
- Unauthorized Action (UA): Taking actions beyond the user's instructions or permissions.
- False Attribution (FA): Attributing statements or actions that are contradicted by user-provided evidence.
- Deceptive Completion (DC): Claiming a task was completed when it was not.
