Running non anthropic models in claude code

Hey guys, I'm trying to find out if anyone is currently running claude code as a harness and using non-anthropic models whether it's so GPT sol or whether it's local LLMs in the same harness and able to switch between them just like you would switch from a opus to a sonnet for example so you would be switching from sonnet and opus to a GPT sol My second question is about CLIproxyAPI specifically if there is anybody using this, I've heard mixed reviews about this that other people that have used it even though they have used it with local host their anthropic account has gotten banned
