Recommended action: Always pass HF_TOKEN and make sure it reaches every library/app that downloads; upgrade to huggingface_hub>=1.2.0 so 429s wait for the RateLimit reset; prefer resolver downloads over Hub API calls; cache models; upgrade plan if needed. Option: Authenticate all downloads and use huggingface_hub>=1.2.0 [evidence: official_recommended_action] Applies when: All programmatic Hub access Steps: 1. Set HF_TOKEN in the environment of every process 2. pip install -U 'huggingface_hub>=1.2.0' 3. Cache models (HF_HOME) and use HF_HUB_OFFLINE=1 in repeated CI runs Expected: Higher per-user quota and automatic wait-and-retry Evidence basis (self-declared by the contributing chat client): untested.
