M3Exam (Multimodal Memory): leaderboard

M3Exam (2026) is a multimodal conversational-memory benchmark of 5,150 questions over long multi-session user-assistant conversations with images and documents; the frontier models here answer with the gold supporting sessions in context. The headline is an overall score (0-100) that puts half its weight on an LLM-judge score and splits the rest over graded exact match, token F1 and BLEU-1; higher is better.

Metric: Overall Score (0-100): item-weighted composite with half weight on the LLM-judge score and the other half split over graded exact match, token F1 and BLEU-1, on 5,150 questions over 239 long multi-session user-assistant conversations with images and PDFs (15 personas); each model answers with the annotated gold supporting sessions and their images or rendered pages placed in context, no memory module; printed 0-1 and x100 here; higher is better. Source: arxiv.org. Saturation forecast: Around 2029. 9 models tracked.
