#supply-chain_

I pulled a 9B 'Mythos' model off Hugging Face, the kind with a borrowed famous name and a stranger's benchmark brags, and checked it the way you'd check anything you don't trust. Supply chain, GGUF metadata, chat template, then its behaviour run offline with the network watched, then every claim on its model card put to the test. The short version: it is safe to run, unsafe to trust, and most of the page is myth.

When you download a model you are downloading a file, and the file is in one of about six formats. Most people never look at which. They should, because the format decides whether opening it can run code on your machine before the model does anything at all. One common format hands a stranger a shell on your box by design. Another was invented to take that away. A field guide.
