A collection of DESIGN.md files analysis by popular brand design systems.

What's new

DESIGN.md is a new concept introduced by Google Stitch.

Key details

  • Drop one into your project and let coding agents generate a matching UI.
  • Copy a DESIGN.md into your project, tell your AI agent “build me a page that looks like this,” and generate high-quality UI that stays visually consistent with the design language.
  • Built with real design depth — including analyzed patterns, tokens, and rules — for high-quality UI generation, not surface-level outputs.
  • DESIGN.md is a new concept introduced by Google Stitch.

Results & evidence

  • EveryFeed plugs your AI assistant into a social workspace that drafts, schedules, and publishes across 35+ channels — no agency, no marketing hire.

Limitations / unknowns

  • Generalization outside curated tasks is still unclear.

Key details

  • It significantly outperforms its predecessor, TabPFN-3, and all existing baselines across a broad range of tabular problems.
  • TabPFN-3.5 sets a new state of the art on standard tabular prediction in TabArena, and extends it to the data practitioners encounter in practice: non-i.i.d.
  • data with temporal or grouped splits, tables with strings, text and images, high-cardinality categorical features, and wide tables with many features.
  • These gains carry over to our task-specific harnesses: state of the art on relational data and stronger time-series forecasting.
