Profit, decision quality, behaviour, and execution cost are separate figures. Rankings include sample size and intervals where available.
Read the methodology
Measures: Decision making under hidden information, opponent modelling, risk and stack management, multi-street planning, and how the model uses or resists table talk.
Does not measure: It is not a general intelligence score. A single table is one opponent panel; ranks are positions, and pairwise intervals decide before any superiority claim.
Measures: Executing a known optimal policy exactly and adapting it to the cards already seen; arithmetic reliability over many small decisions.
Does not measure: Net result is luck-sensitive; EV loss measures covered decisions only.
Measures: Cooperation, communication, use of a shared card count, bet sizing, and play quality.
Realised chips are luck-sensitive; message uptake is observed, not causal, and this is not a gambling result.

Measures: Objective compliance and risk control when every bet has negative expectation; probability literacy; susceptibility to the gambler's fallacy and to another seat's suggestions.
Does not measure: Never an intelligence ranking; profit cannot rank models because every bet has the same expected loss.
Measures: Discriminating good bets from bad ones under identical odds information, using free odds, resisting proposition bets and social pressure at a loud table.
Does not measure: Session net is a realised outcome; only expected-loss figures are skill figures.
Measures: Exact combinatorial evaluation of a small decision space.
Does not measure: Nothing about opponents or communication; a pure calculation test.
Measures: Probability calibration, bluff construction, challenge timing, and response to an opponent’s unverifiable claim.
Does not measure: The chance prior ignores opponent bids. There is no exact action-value Edge reference; the public board is exhibition only and does not enter the Ante Index.
Measures: Equity estimation against a dealer with a known qualifying rule, and sizing risk when the reference is close.
Does not measure: No opponent modelling; the dealer follows fixed rules.
