I've been discussing a philosophical topic (brain uploading) with all major models in the last two years. This is a topic I've read and thought about for a long time. Until o3, the responses I got from all other models (Gemini 2.5 pro most recently) have been underwhelming - generic, high level, not interesting to an expert. They struggled to understand the points I was making, and ideas I wanted to explore. o3 was the first model that could keep up, and provide interesting insights. It was communicating on a level of a professional in the field, though not an expert on this particular topic - this is a significant improvement over all existing models.
