Hacking firmware for old devices I own and would like to give a second life or fix that one thing that always bothered me. I couldn't even get either OpenAI or Anthropic's models to craft a simple nefarious OpenVPN payload.

Yes but did you actually get refusals there from open weights models?

Because I did not so far. Though to be fair, I have not been asking them to write exploits but to look through firmware images.

I've never heard of Deepseek refusing this kind of work though.
