The official source reports this update: [v1.29.0] Fix Xet downloads rate limits, bucket visibility updates, and security fixes. ⚡ Xet downloads no longer make one API call per file Since v1.19.0, downloading a repository with hf_xet eagerly requested a xet read token for every single file, because each download group was built without cached connection info. On repos with many files this quickly added up — a 77k-file repo made ~1,500 Hub API calls per minute — and eventually hit the rate limiter, leaving snapshot_download appearing stalled for minutes before failing with a 429 Too Many Requests .
