I don’t care about 4o’s personality. But o3 pro was consistently better than 5 at dev work. 5 is more affordable and good at tool call planning, but it’s incredibly dumb and you need to give it painfully detailed instructions to get even partially competent results - and anything outside of dev work it really drops the ball compared to o3. On the other hand, o3 pro or Claude can be given a general guideline of what you want done in dev work and reliably take a good stab at it. OpenAI basically realized their only profitable market is people using LLMs for work who will shell out, and so they’ve over optimized to drop API costs, and cut out intelligence that isn’t related to accuracy across dev work/finance etc Great for corporate users with extensive pipelines, shit for everyone else.(Adam Cochran (adamscochran.eth))
