Resources

Official docs, papers, datasets, benchmarks, courses, and communities

This resource list is structured so it can grow into a curated library. Prefer official documentation and primary sources when making implementation decisions.

Source quality rules

Prefer official documentation for tool behavior.
Prefer primary research for scientific claims.
Avoid unverified benchmark claims.
Record last-verified dates for tool pages.
Use community tutorials only after checking against official docs.
