BizGenEval (Easy) - Knowledge-based Reasoning: leaderboard
Metric: Checklist score (0-100): for each generated image a Gemini 3 Flash Preview judge answers the prompt's 10 human-verified easy yes/no questions, the image scores max(0, 1 - 0.2 x errors), so five or more errors give 0, and scores are averaged and shown as a percentage, on the 100 knowledge-based reasoning prompts of BizGenEval (20 per document type: slides, webpages, posters, charts, scientific figures); one image per prompt at the official default settings, resolution set to the nearest supported aspect ratio of the reference design; higher is better. Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 26 models tracked.
