I recently put GPT 4 into my app and it was pretty good at first. But then it was not so good. GPT 4, for whatever reason, decided to take ages to answer my prompts. And also it cost me a fortune to run so I decided to switch from GPT 4 to Google’s Gemini Pro. Just in time for OpenAI to announce they’re dropping their GPT 3.5 prices by 25–50%.
