Subscriptions

For people

• Index Weekly — a Monday email: the top ten, the biggest movers, new entrants and new sources, one chart. Sign up in the sidebar of the Index.

• RSS — publicai.io/model-index/feed.xml: one item per snapshot, listing what changed.

• Watch a view — planned: subscribe to any filtered view (its URL) and receive only that view's card and changes.

For agents

• Poll — GET /model-index/api?since=YYYY-MM-DD or the MCP tool whats_new({ since }). See API.

• Push — planned: register a webhook with a filter (family, scope, threshold); each snapshot that matches is POSTed as signed JSON.

Cadence

Snapshots refresh daily at 06:00 UTC; the feed and since report only what changed. Index Weekly goes out Mondays at 09:00 UTC.
