OpenAI: o3 Pro
Analysis Summary
OpenAI o3 Pro is a frontier reasoning model from OpenAI with an intelligence index of 40.7 and GPQA at 0.845, the highest GPQA score in this batch. It supports tool use, function calling, vision, and file input with a 200K context window, making it a strong fit for complex analytical and agentic workflows.
For businesses, o3 Pro is best suited to tasks where reasoning depth is the primary requirement: scientific analysis, complex document review, multi-step agentic pipelines, and high-stakes decision support. The absence of published coding and agentic index scores limits direct comparison on those dimensions, but the intelligence index and GPQA place it at the frontier of reasoning capability.
At $20.00 input / $80.00 output per million tokens it is among the most expensive models available, making it appropriate only for high-value tasks where reasoning quality is critical. Teams with demanding analytical workloads and budget for premium inference will find it a strong production choice.
