I got frustrated with the new o3-pro mode today. I just wasted a few hours of my day waiting 15-20 minutes for answers that were totally out of line with the workflow I've had since the first o1-pro model came out. It's a completely different beast to work with. It feels like it hits output limits way easier, and you have to work around it. Today after I finally gave up, I just told the model I was disappointed and asked it to explain its limitations. It was actually helpful, and told me I could ask for a download link to get a file that wasn't cut off. But why should I have to do that? It's definitely not more user-friendly and totally the opposite experience as working with Google Gemini 2.5 pro. Honestly, this experience made it obvious how much harder OpenAI's models are to work with now compared to Google's. I've been using Gemini 2.5 Pro and it's super hard to find its limits. For the $20 I spend, it's not even a competition anymore. My new workflow is clear: throw everything at Gemini 2.5 Pro to get the real work done, then maybe spot-check it with the OpenAI models. I'll probably just migrate to the top Gemini ultra tier when the “deep thinking” mode is available. I'm just not happy with the openai experience on any of their models after getting used to the huge context window in Gemini. OpenAI used to at least keep me happy with o1-pro but now that they removed it and o3-pro kind of sucks to work with taking 20 minutes to output and have lower confidence in the time spent, I don’t think I have a reason to default to them anymore. Gemini is definitely more user friendly and my default option now.
