1
Identify the publisher
Read the account name, model card, linked code, and update history. Look for a clear relationship to the source project; do not infer official status from a matching title or thumbnail.
2
Check what is supplied
Separate downloadable weights from runnable code and a hosted demo. Inspect documented dependencies, intended inputs, usage terms, and any limitations before downloading files or submitting footage.
3
Test the claim carefully
If a demo is available, use footage you have permission to submit and compare the result with its source. If it is unavailable, treat the listing as documentation or a file source, not proof of a working service.
