OpenAI: o3 Pro
Analysis Summary
OpenAI: o3 Pro is OpenAIās entry in the o3 line-up. It was released in June 2025. On our leaderboard it earns Efficient-tier status, ranking #152 of 571 models in our overall business-suitability ranking. For raw reasoning ability it ranks #62 of 374, putting it in the top quartile for overall intelligence.
Its 200K-token context window is larger than 66% of the models we list, suiting long documents, large codebases, and retrieval-heavy workloads. Crucially for business adoption, OpenAI: o3 Pro combines tool use, function calling, vision input, and step-by-step reasoning in a single model, letting teams consolidate several use cases instead of stitching together multiple services.
At $20.00 input and $80.00 output per 1M tokens, OpenAI: o3 Pro is among the most expensive options we list, so it is best reserved for high-value work where answer quality matters more than per-token cost. OpenAI: o3 Pro suits cost-sensitive or high-volume deployments where efficiency matters more than topping the benchmarks.
Editorial notes
OpenAI o3 Pro delivers frontier-level reasoning and GPQA scores with vision, tool use, and function calling across a 200K context, though its premium pricing limits cost-sensitive deployments.
