Feeds

Every item is a diff: what changed, old → new, where we saw it, and when. Same data as the pages, no editorial. Subscribe in any reader; newsletters may quote items with a link back.

Feed URLs

Scope	RSS 2.0	JSON Feed 1.1	What's in it
All changes	/feeds/changes.xml	/feeds/changes.json	Every observed change across the watch list, newest first (last 200 items).
New drops	/feeds/drops.xml	/feeds/drops.json	One item per new model drop (models created in the last 60 days by reputable orgs).
Per family	/feeds/families/{org}--{series}.xml	—	Changes to any member of a family. Example: /feeds/families/01-ai--Yi.xml
Per model	/feeds/models/{org}--{name}.xml	—	Changes to one model. Example: /feeds/models/01-ai--Yi-34B.xml

The slug replaces the first / in the Hugging Face id with --; case is preserved. Per-model and per-family links also appear on every page's "Get alerts" box.

Item schema

RSS items: title = {model}: {field} {old} → {new}; description carries the diff, the source_url we observed it at, and observed_at; link is the model page; guid (not a permalink) is a hash of (model_id, field, observed_at), so re-fetching never duplicates an item. Repo commits and new drops use the titles {model}: repo commit — {title} and {model}: new model drop.

JSON Feed items add a _diff extension with the raw fields:
