o3 moves to version o3 (o3-2025-04-16)

The OnAirToday AI Progress Tracker recorded a verified change to OpenAI's o3 (version o3 (o3-2025-04-16)): Version now o3 (o3-2025-04-16) (was o3).

OpenAI o3 is a reasoning model supporting text and image inputs, with documented strengths in mathematics, coding, scientific reasoning and visual analysis. OpenAI subsequently released o3-pro as a separate higher-compute variant; its results and pricing do not apply to this profile.

What changed in this review:

• Added OpenAI's published GPQA Diamond, SWE-bench Verified, AIME and MMMU results, preserving their evaluation dates.
• Removed benchmark entries without established supporting evidence for their exact scores and evaluation configurations.
• OpenAI released o3-pro on June 10, 2025, as a separate higher-compute variant; this profile remains about o3.
• Clarified that pricing is USD per million tokens: $2 input and $8 output, with reasoning tokens billed as output.
• 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.
