I cancelled Claude. The harness is kinda broken, GPT 5.5 is good, and GLM 5.2/Deepseek is good too (with pi, especially). Just not worth the trouble. And I'm not going to pay two subscriptions.
Recent update resulted in 100% permanent CPU load in the background, when doing nothing with the app. Basically unusable on a notebook (hot+noise, unexcusable for do nothing "api/command coordination" terminal app). Dunno if they fixed it, since I could not use it on the notebook and I do not have this issue on my workstation.
