Tracked models ranked by Score (higher is better).
Notes: Official Anthropic launch table starred the 64.5% HLE with-tools score as Claude Mythos 5. The 59.0% no-tools variant is recorded in the handoff but not seeded because modelBenchmark rows are unique by modelSlug and benchmarkSlug.
Notes: Model variant: Kimi K3 (max reasoning effort). Benchmark variant: HLE-Full without tools. Harness/evaluator not disclosed by Moonshot. Source posture: Moonshot/Kimi self-reported launch table; confidence: medium because the value is vendor-reported and not independently reproduced. Recommended seed value: 43.5.

Trust this score when
- There is a fresh timestamped snapshot (or multiple snapshots) for this benchmark.
- The model list covers the same version family you can actually deploy today.
- Top candidates overlap with your required routing and feature requirements.
Be cautious when
- There is only one benchmark snapshot or the dataset appears stale.
- The benchmark metric direction is opposite of your decision objective.
- The score difference between options is narrow and likely within implementation variance.
