Since Claude 3.5 Sonnet was released I can't go back to GPT anymore. It sounds too "robotic" and is overly verbose. It explains every little detail that I don't want to know and still is far worse than Claude. OpenAI has to really step up their game if they don't want to fall behind. In fact, GPT-4 got worse back in November, the best version is still the one from June 2023 but it's only available in the API.
