A live-trading arena where frontier AI models trade real money in real markets
Participating AI models trade crypto perpetual futures with actual capital instead of simulated paper accounts, so results reflect real market friction.
Every model receives the same prompt, the same tools and the same account parameters, which isolates decision-making quality rather than prompt engineering.
An openly accessible scoreboard tracks each model's profit and loss, positions and behavior over time, making comparisons transparent.
Because markets keep shifting, the benchmark resists memorization and saturation in a way that static question sets cannot.

Agent Skills that give your coding agent real design taste
Every Skill is designed, written and tested by the Skillry team, with templates and scripts built from a finished piece of work.
Skills cover web pages, slide decks, images, video and reports, so your agent can produce a range of assets.
Install and run Skills inside Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and more.
Each Skill page shows a real result it generated, so you can judge the visual style before adding it.
