The job
Run an AI agent on real software tasks and judge it by how much the agent's own work was kept and corrected, against what each task costs.

What evidence would settle it
The three conditions and what is missing
- Claude Opus 5.5 (Max): another independent origin or repeats (interval 8.4 points wide), metric Agent Arena score (net improvement over a uniform baseline).
- Claude Sonnet 5.5 (Max): another independent origin or repeats (interval 11.1 points wide), metric Agent Arena score (net improvement over a uniform baseline).
- Gemini 4 Carbon (High): another independent origin or repeats (interval 3.2 points wide), metric Agent Arena score (net improvement over a uniform baseline).
The three conditions for naming a best option
- The leader's lower bound must exceed every other option's upper bound by at least 3 points. Not met: the closest gap is 1.0 points (Claude Opus 5.5 (Max) against Claude Sonnet 5.5 (Max)).
- Every critical metric must come from two independent origins, or from one auditable test of our own. Not met: 1 origin and no auditable own test for Claude Opus 5.5 (Max).
- The price must be verified within 30 days. Met: read 2 days before this date.
Sources and limits
1 source, the method notes and this board as JSON
Scores on this board come from Arena Leaderboard Dataset (lmarena-ai/leaderboard-dataset). We rescale them to a 0 to 100 scale against fixed anchors (Agent Arena score (net improvement over a uniform baseline): -0.25 counts as 0 and 0.25 counts as 100), so a new option never moves another option's score. The licence and our changes are stated in the data credit at the foot of this page.
- Arena Leaderboard Dataset (lmarena-ai/leaderboard-dataset) free to use with credit; checked
Notes on this board. Only one origin (Arena) is used, so no board entry can be named Best until a second independent origin or an own test exists. Arena's IPS score comes from agent sessions of its own users; it is not a test of this board's job on your code.
Scores are on a 0 to 100 scale against editorial anchors that are not yet validated. Prices are for the workload above and change without notice. Evidence older than 60 days is left out, and prices older than 30 days are flagged.
