Doesn’t using the Anthropic subscription this way get charged as extra usage, and thus effectively billed at API rates?
Oh, I stand corrected. It's been a while since I've used their models.
Glad we can still use OpenAI subscription through Pi.
I use my Anthropic subscription with Pi. I thought they would start charging me API usage at some point, but it never happened. (If it did happen, I would switch to open weights models.)
...funnily enough, a few hours after posting this, it stopped working.
Not if you run your own system prompt that does not explicitly contain the term "pi coding agent". Perhaps they string-match against some other stuff, too, but as long as you paraphrase the system prompt a bit, you should be fine.
That's hilarious
They had plans to do that for CLaude SDK and claude -p usage, but paused them indefinitely.
