Photonic PCFBench - Parameter Modification Syntax: leaderboard

PCFBench v1 Appendix full results; 26 isolated tasks across six categories; temperature0.1, task-specific64–2048token budgets; native fractions/errors. Paired structure+field and Field-only contexts separate. Closed-loop success uses expert sign/magnitude constraints, not physical resimulation; Human Score mean of six dimensions/two experts on120samples. Source-disputed summary/appendix cells and unbound checkpoint variants withheld.

Metric: Syntax correctness. Source: arxiv.org. Saturation forecast: Estimated already saturated. 29 models tracked.
