How smart is o3-pro?

119 SI-IQ · 90% interval 103–135
Not ranked: results from fewer than 5 benchmarks; results in fewer than 3 areas; results from fewer than 2 evaluators

o3-pro is a model from OpenAI, released on Jun 10, 2025. Its SI-IQ is 119 (90% interval 103–135), estimated from 1 benchmark result by 1 evaluator.

Data as of Oct 18, 2026 · method 1.0.0

A model is ranked when its results come from at least 5 benchmarks (the two GPQA Diamond runs count as one) in at least 3 areas, from at least 2 different evaluators, and its versions are released no more than 60 days apart. This model does not meet that yet (results from fewer than 5 benchmarks; results in fewer than 3 areas; results from fewer than 2 evaluators). Its provisional estimate rests on 1 benchmark result and can change a lot when more results arrive.

Facts

Developer: OpenAI
Released: Jun 10, 2025
Access: API access
Benchmarks used: 1 benchmark result from 1 evaluator

Every benchmark result we used

Each score is one value exactly as the source published it: for Epoch AI the best of its run settings, for OpenRouter the median hosting provider (the developer's own hosting when it ran the test). “Implied SI-IQ” is the ability that this single result points to; the overall SI-IQ is their precision-weighted average.
