The contradiction between the one celebration and third celebration benchmark outcomes of Openai’s O3 AI mannequin I elevate questions on firm transparency Observe mannequin testing.
When Openai unveiled the O3 in December, the corporate claimed that the mannequin might reply greater than 1 / 4 of questions on Frontiermath. That rating blew the competitors – the following finest mannequin answered solely about 2% of the Frontiermath downside appropriately.
“All merchandise on the market immediately are beneath 2% [on FrontierMath],” Mark Chen, Chief Analysis Officer at Openai; I mentioned this throughout the stay stream. “We’re watching [internally]O3 is in aggressive take a look at time calculation settings, so it may possibly exceed 25%. ”
In spite of everything, that determine might be a cap, achieved by the model of O3, which has extra computing than the mannequin Openai launched final week.
Epoch AI, the laboratory behind Frontiermath, introduced the outcomes of the O3’s impartial benchmark take a look at on Friday. Epoch discovered that O3 scored round 10% nicely under Openai’s highest billing rating.
Openai has launched the extremely anticipated inference mannequin, O3, together with the O4-Mini, a smaller and cheaper mannequin that takes over the O3-Mini.

That does not imply that in itself was a lie. The corporate-issued benchmark outcomes revealed in December present decrease sure scores that match the noticed rating epoch. Epoch additionally mentioned that the setup for that take a look at would probably be completely different from Openai’s setup and used the up to date launch of Frontiermath for its analysis.
“The distinction between our outcomes and Openai could possibly be as a result of the truth that Openai is evaluated with a stronger inner scaffold and use extra testing time [computing]or as a result of their outcomes have been carried out on a unique subset of Frontiermath (180 points in Frontiermath-2024-11-26 and 290 points in Frontiermath-2025-02-28-Personal),” I wrote it epoch.
In keeping with X’s publish The general public O3 mannequin is “a unique mannequin” from the ARC Awards Basis, the group that examined the pre-release model of the O3. […] We’ll tailor it to your chat/product use,” confirms Epoch’s report.
“All launched O3 computing layers are smaller than our model [benchmarked]wrote the ARC Award. Usually talking, you possibly can count on a bigger computing layer to realize a greater benchmark rating.
It takes a day or two to retest the O3 on ARC-AGI-1. Right this moment’s releases are just about completely different programs, so we’re reevaluating previous reported outcomes as “previews.”
O3-PREVIEW (LOW): 75.7%, $200/activity
O3-PREVIEW (HIGH): 87.5%, 34.4K/activityI will use the pricing for the O1 Professional above…

Openai’s personal Wenda Zhou, a member of the technical employees; I mentioned this in final week’s stay stream The manufacturing O3 is “optimized by precise use instances” and pace in comparison with the model of O3 that was demoed in December. The outcome might point out a benchmark “disparity,” he added.
“[W]It is completed [optimizations] Make it [model] It is more cost effective [and] Zhou mentioned: […] If you end up searching for solutions, you needn’t wait lengthy, that is these true issues [types of] Mannequin. ”
Actually, the truth that the O3’s public launch has not reached Openai’s testing promise implies that Frontiermath’s O3-Mini-Excessive and O4-Mini fashions outperform the O3, so OpenAI can be debuting a stronger O3 variant, the O3-Professional, within the coming weeks.
Nonetheless, remind your self that AI benchmarks are finest not taken at face worth, particularly if you’re an organization that has a service that the supply sells.
As distributors compete to seize headlines and mindshares with new fashions, benchmark “controversy” is turning into a typical prevalence within the AI business.
In January, Epoch was criticized for ready for the corporate to reveal funds from Openai till after it introduced the O3. Many students who contributed to Frontiermath weren’t knowledgeable of Openai’s involvement till it was revealed.
Lately, Elon Musk’s Xai has been accused of publishing a deceptive benchmark chart for its newest AI mannequin, the Grok 3. This month, Meta confirmed that the corporate will promote benchmark scores for variations of fashions which might be completely different from these accessible to builders.
4:21pm Pacific: From final week’s stay stream, we added a remark from Wenda Zhou, a member of Openai technical employees.
