The Gemini 2.5 Pro hits the mark with native multimodal input, a million-token context length, and superior benchmark performance, particularly in programming and reasoning.

Overall, Gemini 2.5 Pro again provided more accuracy and reliability throughout the response, so it was clearly the winner. Ultimately, there was no comparison as o3 pro was more convoluted and entailed a more elaborate analysis.
