[Re-verified in clone 2026-07-07: PhyX_process_line_MC at phyx.py:336-375, PhyX_auxeval_MC at :218-254 (letter mismatch scored 0 without judge at :236-238), evaluate valid_type assert at image_vqa.py:3448-3455, phyx.yaml:9-10.]", | |
| "note": "Official judge model is deepseek-chat. Rule-extracted letters that mismatch are scored 0 without a judge call; the judge only handles non-letter/verbose responses. mm-eval ships only the MC subset (phyx_mc + phyx_mini_mc splits); official OE subset and its text-only variants are not published. NOTE: phyx_mini_mc's 1000 ids are fully contained in phyx_mc's 3000 — pooling both splits double-counts the mini rows; evaluate one split at a time." | |
