I am a CC user on the 20x, 5x is too small for me. Doing some quick maths I found that the Anthropic subscription it is a bargain compared to other models on API usage.

Does using Pi saves you so much token overhead that my maths are wrong?

There are some extensions you can use to use your claude subscription on Pi, it runs Claude Code under the hood but with pi's prompts. The same is possible with Opencode

There is no 20x any longer, no?
