`pi` can apparently no longer work with Claude subscription

[totoroot]

What happened?

Servus Mario,

I have started using pi with my OpenAI/Codex business subscription just yesterday and am thoroughly impressed. It is so much more pleasant than working with the Codex CLI or OpenCode. It seems to be exactly what I was waiting for to actually productively use LLMs instead of spending time fighting the tooling. Enough smearing honey around your mouth.

Today I tried on a personal machine with my Claude Pro subscription and it no longer seems to allow for a third-party tool like pi with the subscription 👀

What can you help me with?

The login session authenticates fine:








First I thought it was because I installed pi through a Nix package, but even when installing the recommended way, I end up at this roadblock.

So Claude Code CLI itself seems to be effected by their billing change took effect on the 4th of April:
anthropics/claude-code#45134
anthropics/claude-code#45013

Any ideas how to work around this?

Apparently someone found a workaround for OpenCode:

we don't provide work arounds. as per the message as that's a ToS violation, you'll need to.enable extra usage and get billed by token.

[totoroot]

Oh okay, that surely make sense. Thanks for the prompt response.
Then after the billing change by Anthropic, Claude subscription likely has to be removed from https://github.com/badlogic/pi-mono/tree/main/packages/coding-agent#providers--models, right?

[totoroot]

@badlogic Sorry for the noise.

I hoped for being able to use Claude subscription, due to finding it listed in the README. I did not register that doing so would violate the ToS. Will follow up on Discord.

I am not affiliated with Pi in any way.

Out of research interests only, I have published pi-anthropic-auth.

I recommend using AI vendors that are more supportive of the community but you're welcome to try the plugin/extension, fork it, whatever.

@gotgenes you are a scholar and a gentleman
