VTC-Bench (Interface Tools) - Measurement: leaderboard

Metric: Pass rate (%) on measurement (105 questions on size, position and shape), answering VTC-Bench's 680 visual questions (538 multiple-choice, 142 open-ended) that call for chains of image operations with the same 32 OpenCV-based tools invoked through a function-calling interface, up to 20 rounds; rule matching plus a GPT-4o judge for open answers; proprietary models in high reasoning mode; higher is better. Source: arxiv.org. Saturation forecast: Around 2031. 19 models tracked.
