11How would you check a public pre-trained model for a backdoor, and what can you not detect?▼hardNewGoogle DeepMindMicrosoftMeta◆ premiumYou can check the file and test the behaviour; you cannot prove a negative. The scored answer separates code-level threats from learned backdoors and is honest about what testing can find.Open full answer →
14What scans and admission policies would you require before an open-weights model runs in production?▼mediumNewHugging FaceDatabricksMeta◆ premiumOpen weights arrive with code, configs, licences and unknown training. The scored answer turns due diligence into a repeatable gate that production enforces automatically.Open full answer →
15Write a check that verifies downloaded model and dependency files against pinned hashes before they are used.▼mediumNewGoogleMicrosoftHugging Face◆ premiumPinning a version is not pinning content. The scored answer verifies every file against a recorded hash, treats unexpected and missing files as failures, and explains where the lockfile's own trust comes from.Open full answer →
22What do model file scanners detect, and what do they miss?▼mediumNewHugging FaceMicrosoftPalo Alto Networks◆ premiumScanners are good at one thing: spotting code where only data should be. The scored answer explains how they work, how they are evaded, and why a clean scan is not a clean model.Open full answer →
