Blind human preference where the two have met, then each model's arena-wide results side by side.
In eligible head-to-head comparisons, Inkling has a 33.3% decisive win rate and Kimi K3 has 42.9%. 23.8% end without a decisive preference. These observed rates do not establish which model is best on every task.
These are arena-wide results. Each model encounters a different mix of tasks and opponents. The direct matchup, when available, is reported separately.

| 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. | 8–16 | 3–12 |
| Win rate · all opponentsDecisive wins / eligible comparisons. Ties stay in the denominator. Opponent mixes differ. | 30.3% | 36.1% |

No. Completion for Inkling and Kimi K3 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.
