Are open weights models secure? E.g. if a Chinese model is run by an American provider then can it still do bad things, like inserting backdoors into generated code or accessing external URLs (if browsing is enabled) to send info to them? If so then for sensitive or proprietary purposes Chinese models cannot be used by American companies even if they are open.
What prevents an American model from doing the same? They’re all black boxes.
So every country or block needs to run their own models to avoid opening a security hole for other countries.
