The world's most-powerful AI model suddenly got 'lazier' and 'dumber.' A radical redesign of OpenAI's GPT-4 could be behind the decline in performance.
The only way in mind this dumbing down happens is by fumbling with the model. So that's the one thing we can be sure: the AI is most definitely changed while publicly staying "ChatGPT 4". I assume they are either using clipping or token limitations to split the server load but fucking up the result, or they are purposely dumbing it down to capitalise on it later by introducing other pay models like ppl already mentioned.
Either way they are shooting themselves in the foot because a bunch of ppl will unsubscribe either out of spite for the change or because it's just not worth it anymore for them.
