Computer-use model comparison
There are no eligible head-to-head results for GPT-5.6 Sol and GPT-6 Luna in the current ranking window. Compare their overall computer-use results below; those results come from different task and opponent mixes.
These are arena-wide results. Each model encounters a different mix of tasks and opponents. The direct matchup, when available, is reported separately.
| Measure | GPT-5.6 Solstable | GPT-6 Lunaprovisional |
|---|---|---|
| Leaderboard rankThe 95% rank band from the arena's Bradley–Terry fit. A range means the data cannot separate those positions; a model under the provisional floor takes no rank. | 1–7 | Unranked |
| Win rate · all opponentsDecisive wins / eligible comparisons. Ties stay in the denominator. Opponent mixes differ. | 38.6% | 38.9% |
| CompletionAgent-reported completed runs / non-synthetic arena runs. Completion is not independently verified success. | 81.8% | 79.5% |

No. Completion for GPT-5.6 Sol and GPT-6 Luna records whether the agent reported finishing. Human preferences, task success and next-action recovery are different measurements.
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.
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.
