Sorry, sounds like total bullshit. The weights aren't going to do anything. And if you are worried about the code, with current deployment practices of curl | sudo bash there are much more low-hanging fruits out there. That's not even mentioning the possibility of running the model on a PC without internet access (no matter how good the new Chinese AI is, it's still not good enough yet to convince you to let it out of the box).
Don't give it mcp then (and I struggle to understand why would anyone give a stochastic model such access even if it is trained on very American NSA-certified hardware approved by Sam Altman himself).
