BioXArena-Pro - Mean 64 - Harness Codex CLI: Native task score x100, failures zero (0-100). BioXArena-Pro release v5.1.1: 64 biomedical ML tasks, 8 domains x8, every score 0-100 and failed task zero, one run/configuration/task, 1 GPU and 7200s/task. Primary CSV retains exact model_dir, scaffold, backend, route, own-run mean, substituted tasks and all domain scores. MLEvolve Opus 5.5 source substitutes two Opus 5 results; its mixed mean/domain panels are held. Other 21 configurations retain separate harnesses and served model identity (DeepSeek V4.1 Flash 1017). Gateway machine/routing differences are retained, never inferred from current defaults. Cost/time/token columns not capability. Runtime effort unreported. Native source condition: Harness Codex CLI.
Metric: Native task score x100, failures zero (0-100). Source: raw.githubusercontent.com. Saturation forecast: Around September 2027. 2 models tracked.
