The OnAirToday AI Progress Tracker recorded a verified change to OpenAI's o3 (version o3): OpenAI released o3-pro on June 10, 2025, as a higher-compute variant; this profile remains about o3.

OpenAI o3 is a reasoning model for complex coding, mathematics, scientific analysis and image-based problem solving. It supports tool calling and structured outputs through the API; o3-pro is a separately released, higher-compute variant.

What changed in this review:

• OpenAI's published GPQA Diamond result is 83.3%; its SWE-bench Verified result is 69.1%, under vendor evaluation conditions.
• Added published AIME 2025 and MMMU results.
• Added documented capabilities, limitations and safety risks.
• Flaws and limitations updated
• Risks and threats updated

Teams building on o3 should confirm limits, pricing and benchmark coverage against the vendor's own documentation before relying on these figures.

The full profile — capabilities, benchmark citations, known flaws and risk guidance — is on the tracker at /ai-models/o3.
