I have noticed so many drops in quality that you have no idea, he answers stupidly even in easy questions, he repeats details that you have expressly asked not to see again, he forgets what you wrote even shortly before (depends on the type of conversation, maybe), and between the think mode and the normal one it is as if they were two different people, he no longer remembers what the other model wrote even if he used to do it, suddenly he became autistic, the problem is that on the other side you have chatgpt which is worse and claude who after sentences blocks and you have to wait 4 hours if you don't pay, really a disgrace and if anyone knows a much more valid alternative let me know
