Are you paying per-token after Anthropic closed the loophole on letting you log in to OpenCode?
When did they successfully close the loophole? I know they tried a few times, but even the last attempt from a week or two ago was circumvented rather easily.
If one has a github sub, you can use OpenCode -> github -> \A models. It's not 100% (the context window I think is smaller, and they can be behind on the model version updates), but it's another way to get to \A models and not use CC.
