There was some issue with sign-in, it seems pin requested via web does not work in console (so the web suggesting using --pin option is misleading).
I tried BYO plan as I already have openrouter API key. But it seems like default model pack splits its API use between openrouter and openai, and I ended up stuck with "o3-mini does not exist".
And my whole motivation was basically trying Gemini 2.5 Pro it seems like that requires some trial-and-error configuration. (gemini-exp pack doesn't quite work now.)
The difference between FOSS and BYO plan is not clear: seems like installation process is different, but is the benefit of paid plan that it would store my stuff on server? I'd really rather not TBH, so it has negative value.
