Which competitor has alternative to ChatGPT Pro? I have Claude subscription and Opus 4.1 is not on the same level. ChatGPT Pro thinks for 5-10 minutes, while Opus either doesn't think at all or thinks very briefly. And response quality is absolutely different. ChatGPT Pro solves problems, Opus does not. Is there any competitor with "Pro" product which spends significant amount of computing for a single query?
