The problem is you can't reverse engineer what was baked into the weights because they are just weights. You'll never know if you've fixed everything because it's not always going to be as obvious as request refusal. It's also not binary where you can fully confirm something is fixed or if you've accidentally affected something else.

They're for sure impressive but I don't see how anyone can push them as "open" when they are literally binary blobs. Worse, because it's not practical for anyone to actually train LLMs that can even come close to competing with the ones corporations are pumping out.
