Settings > Model downloads can send Hugging Face downloads through hf-mirror.com, on by default for the Chinese interface. The lookup and the download use the chosen host whichever one the link names; when the mirror sends a network outside China back to huggingface.co, the lookup follows once for the size and SHA-256. A failed download from Hugging Face itself suggests the mirror. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
