Research

Two kinds of page live on this site. Current documentation for the ML packages is generated from the repositories at pinned commits and lives under /ml/; it changes whenever the pins move. Dated narratives, listed below, were written at a point in time and are kept as historical records with their banners and text preserved.

When a narrative and the current documentation differ, the current documentation and each repository's docs/claims.json are the statements to quote. A benchmark paragraph in a historical narrative records what was true when it was written; it never overrides a current claim, and a number that has since been retired or superseded in the register stays retired regardless of what the narrative says.
