> To everyone here pushing for total proliferation of open models -- what should be done about open weight bioweapon and cyber-offense capabilities?

Nothing should be done. These things are trained on public knowledge. The dangerous information is already out there. If someone wants to do something horrible, making it slightly inconvenient isn't going to do much. Hackers and terrorists existed before AI. Just as an example, it's no secret how you would build a nuclear bomb. The practicalities of doing so are much harder, obviously, but the knowledge of how they work and what it would take to make one is not a secret. Security through obscurity has never worked!
