An organization developing math benchmarks for AI didn't disclose that it had received funding from OpenAI until relatively recently, drawing allegations of impropriety from some in the AI community.
Epoch AI, a nonprofit primarily funded by Open Philanthropy, a research and grantmaking foundation, revealed on December 20 that OpenAI had supported the creation of FrontierMath. FrontierMath, a test with expert-level problems designed to measure an AI's mathematical skills, was one of the benchmarks OpenAI used to demo its upcoming flagship AI, o3.
In a post on the forum LessWrong, a contractor for Epoch AI going by the username "Meemi" says that many contributors to the FrontierMath benchmark weren't informed of OpenAI's involvement until it was made public.
"The communication about this has been non-transparent," Meemi wrote. "In my view Epoch AI should have disclosed OpenAI funding, and contractors should have transparent information about the potential of their work being used for capabilities, when choosing whether to work on a benchmark."
On social media, some users raised concerns that the secrecy could erode FrontierMath's reputation as an objective benchmark. In addition to backing FrontierMath, OpenAI had visibility into many of the problems and solutions in the benchmark — a fact that Epoch AI didn't divulge prior to December 20, when o3 was announced.
In a post on X, Stanford PhD mathematics student Carina Hong also alleged that OpenAI has privileged access to FrontierMath thanks to its arrangement with Epoch AI, and that this isn't sitting well with some contributors.
"Six mathematicians who significantly contributed to the FrontierMath benchmark confirmed [to me] ... that they are unaware that OpenAI will have exclusive access to this benchmark (and others won’t)," Hong said. "Most express they are not sure they would have contributed had they known."
In a reply to Meemi's post, Tamay Besiroglu, associate director of Epoch AI and one of the organization's co-founders, asserted that the integrity of FrontierMath hadn't been compromised, but admitted that Epoch AI "made a mistake" in not being more transparent.
"We were restricted from disclosing the partnership until around the time o3 launched, and in hindsight we should have negotiated harder for the ability to be transparent to the benchmark contributors as soon as possible," Besiroglu wrote. "Our mathematicians deserved to know who might have access to their work. Even though we were contractually limited in what we could say, we should have made transparency with our contributors a non-negotiable part of our agreement with OpenAI."
