BannerRequest400 Benchmark

Logo images

The 100 logos were generated semi-automatically with the assistance of Claude-3.5 Sonnet. We manualy checked the content to ensure quality. We release both the rendered .png format (BannerRequest400/logos_png) and the raw .svg format (BannerRequest400/logos_svg) to suit custom needs.

Accompanying the 100 logo images are 400 abstract banner requests (BannerRequest400/abstract_400.jsonl) with four different target-purpose pairs for each logo. The abstract banner requests are derived from the DESIGNERINTENTION proposed in COLE [1]. We use GPT-4o for the target-purpose pair creation.

We also extend the 400 abstract banner requests to 5200 concrete requests across 13 standard banner dimensions with detailed banner specifications (BannerRequest400/concrete_5k.jsonl) via GPT-4o.
