OpenAI's o3 AI model has come under scrutiny after independent tests revealed it scored around 10% on the FrontierMath benchmark, significantly lower than the company's initial claim of over 25%. The discrepancy has raised questions about OpenAI's testing practices and transparency. Epoch AI, which conducted the independent assessment, noted that differences in testing setups and versions could account for the variance. OpenAI's earlier benchmarks matched Epoch's lower-bound score, suggesting some accuracy in their claims. Critics argue that AI benchmarks should be approached with skepticism, particularly when tied to corporate interests.
