# Scry Research

> Benchmarks and cost/performance results for vision-language models and agents doing mobile UI and Figma-to-Storybook diff review.

Scry Design Diff Eval is a 311-pair benchmark of human-reviewed mobile UI defects.
Each pair is a reference screenshot and a generated implementation screenshot with
explicit defect tags and normalized selection boxes. The primary metric is
known-issue recall under strict tag-and-box matching.

- [10–100× Cheaper Design Diffs: A Judged 60-Screen Scorecard](https://blog.scrymore.com/blog/cheaper-design-diffs-cascade/) (September 25, 2026): On 60 Figma-to-Storybook screens with judged truth, a deterministic pre-filter plus one cheap vision call matches Claude Opus 5.5 xhigh's recall of human-tagged defects for $0.0045 a screen instead of $0.54. Scry's Basic and Plus tiers, built on it, find 89% and 94% for $0.009 and $0.05.

The Figma node remembers it.

The cheapest run that still finds the structural problems now costs under a cent.

- [Can VLMs Review Mobile UI? Introducing Scry Design Diff Eval](https://blog.scrymore.com/blog/introducing-scry-design-diff-eval/) (July 3, 2026): Scry Design Diff Eval is a 311-pair benchmark of human-reviewed mobile UI defects. The best vision-language models recover roughly two fifths of known issues.
