DexHoldem Agentic Perception - Turn Ownership: leaderboard
DexHoldem agentic perception bench (Chen et al., 2026): an agent in its native harness (Codex, Claude Code or Gemini CLI) at a medium thinking budget parses one captured poker-table image, given earlier states, into the structured game state; 36 problems, mean of three runs. Accuracy in percent on whose turn it is, on all 36 problems; higher is better.
Metric: Field accuracy (%; whose turn it is, all 36 problems; 36 tabletop states from real games, mean of three runs; the perceiver parses the image with its harness at a medium thinking budget). Source: arxiv.org. Saturation forecast: Estimated already saturated. 8 models tracked.
