MCSBench - L1: leaderboard
Measures multimodal conceptual-structure alignment on MCSBench, a diagnostic multiple-choice benchmark of 661 base visual question-answering items over fine-grained visual and taxonomy-like categories. L1 is the perceptual grounding level: attribute-concept binding in fine-grained visual categories. These are base-VQA accuracies from the released results table; the reasoning-chain integrity overlay, which carries the fourth metacognitive-verification level, is scored separately and is not part of this series. Five API models also have a run with web search enabled in that table; those runs are not part of this series either. This series reports MCSBench - L1 using Accuracy (%).
Metric: Accuracy (%). Source: huggingface.co. Saturation forecast: Estimated already saturated. 77 models tracked.
