In my experience so far, GPT-4o seems to sit somewhere between the capability of GPT-3.5 and GPT-4. I'm working on an app that relies more on GPT-4's reasoning abilities than inference speed. For my use case, GPT-4o seems to do worse than GPT-4 Turbo on reasoning tasks. For me this seems like a step-up from GPT-3.5 but not from GPT-4 Turbo. At half the cost and significantly faster inference speed, I'm sure this is a good tradeoff for other use cases though.
