I used it for a bit.

It is alright to get an LLM review on code I write myself, but getting extra tokens is expensive, and it was not clear if I could configure it to use one of the API keys I have from GLM, MiMo, etc.

I tried Air as well. It was alright, but I found it a bit more cumbersome to use then Pi. I tried configuring Pi to be accessed though ACP, but it felt like going through a hoop to have a worse experience. Then again, I am not someone that manages multiple agents in parallel, at most I have one agent implementing something in a different repository while I am doing my own things.

Air could maybe be useful for me if I could plug in the LLMs I actually use directly, it is too tied to ChatGPT, Claude, etc.
