Each profile belongs to the named configuration. Capability scores use a shared panel for all axes, distinct from the overall ranking panel; they are not accuracy percentages or direct head-to-head wins.
Capability score evidence
Claude Opus 4.6 · Max: 40.8 overall comparison score. Meets the overall evidence requirements.
Shared-result disagreement. This aggregate order conflicts with matched benchmark results against 1 other configurations. Different test coverage and opponents affect the fit. Inspect published results before treating the rank as conclusive.
Which sources carry the weight?
- Artificial Analysis · 28.0% direct comparison weight · independent of the model provider
- Epoch AI · 26.6% direct comparison weight · independent of the model provider
- ARC Prize · 25.0% direct comparison weight · independent of the model provider
- Scale · 20.4% direct comparison weight · independent of the model provider
Which benchmark families carry the weight?
- ARC-AGI · 25.0% direct comparison weight
- Humanity’s Last Exam · 23.1% direct comparison weight
- GPQA · 8.3% direct comparison weight
- Aime · 5.6% direct comparison weight
- epoch-game-puzzles · 5.3% direct comparison weight
- Other families (11) · 32.7% direct comparison weight
These shares describe direct comparison weight, not fractions of the final score or confidence. Source balancing does not give every family equal weight or remove correlations between overlapping sources.
How sensitive is this score?
The audit removes one source at a time and refits against the same overall reference panel. These published results use the matching dataset audited 2026-10-23.
Both ranks use the same surviving configurations for each removal. The cohort starts with 444 configurations supported in the original audit, including separate effort settings. These are diagnostic positions, not the default leaderboard ranks. Eligibility is not rechecked after removal.

Lost support means a configuration no longer has a comparison path to the complete reference panel. Its rank is unavailable. A surviving path alone does not establish leaderboard eligibility.
Overlapping sources may remain correlated even with source balancing. Leave-one-source-out movement is a sensitivity diagnostic, not a spread of source-specific ranks or a confidence measure. Scoring methodology · Dated configuration audit

What evidence is missing from the fit?
Across all collected settings for this model: 120 observations, 70 contributing, 0 matched without graph weight and 50 excluded. Counts do not establish rank eligibility.
- 3 · Benchmark family or source protocol has not been reviewed
- 2 · Effort is not identified
- 4 · Fewer than two distinct model identities remain in this evaluation
- 27 · Cited comparator requires original evaluation provenance; not a new matched run.
- 6 · Supporting evidence outside the reviewed capability core
- 7 · No reviewed effort for this catalog observation; any separately collected effort measurement is counted separately
- 1 · Microsoft report Table 11 and section 4.1: MAI Terminal-Bench removes timeouts and uses a minimal ReAct harness; comparator values are cited from other model releases. A common evaluation protocol is not established.

What these comparisons mean
Each source reports its own effort labels. Matching labels do not establish equal compute budgets or identical fallback behavior. Open Reported settings to inspect the exact model name, agent and task coverage. Multiple results at one level remain visible rather than selecting the best. Source-reported None or Non-reasoning labels are not treated as evidence that an API supports those settings.
These measurements use their own dated source collection. The leaderboard fits identified configurations jointly; it contains no pooled model ratings. Explicit thinking budgets are separate configurations. Read the methodology.
