Seen a couple of people on X have posted about their Claude accounts being suspended after using this. All of them seem to have used it with Claude Code so yes looks like it violates their policy (not surprising really, it breaks their TOS).
I've tried it on Codex (ChatGPT Pro) and within an hour of just getting stuff set up and tested used half my weekly limit so I can see using $300 in a couple of days being very easy.
Until thats figured out this is basically a non starter, you can't use it if its going to cost $1k+ per week to use, and I'm not sure theres any local models that'd handle it without $10k+ in hardware costs.
