I personally don't use Pi but Zed, but Claude is plugged using ACP on my Pro plan. I would never pay the API prices that's way too expensive.
I was under the impression that using Pro or Max from any harness but Claude Code was clamped down upon and likely to result in a ban so haven’t pursued it.
Huh, I guess not.
You can still use harnesses/adapters that use ‘claude -p’ to connect behind the scenes. But the billing is extremely unclear, and it sounds like they use ‘more plan per token’ than just using Claude Code.
The Support page is very unclear, mentioning that you now get an allowance of tokens (and not mentioning the Pro plan at all in that section), and also saying that they’re backing off on plans they previously announced in June without saying what those those plans were, or what the status quo before them was:

…and there’s also this GitHub issue showing that tokens are ‘more expensive’ when using `-p`:
I feel like the max CC plans are incredible value.
