No lmms-eval or VLMEvalKit task exists (re-confirmed 2026-07-07: no visualmrc task in either local clone).",
"note": "Generative reading-comprehension answers graded with captioning-style reference metrics over a single reference answer per question; paper declares no single headline — ROUGE-L listed first here since the paper selects models by ROUGE-L. Official tables also report BERTScore (now representable in the caption_metrics enum but kept out of params to match the paper's core four). metadata.json prompt citation of lmms_eval/tasks/visualmrc is bogus — must be corrected."

Bare-question T2 chosen because answers are abstractive full sentences graded with reference text metrics — a short-answer cue would suppress the expected long-form output."
