Recently, an OpenAI employee publicly criticized Elon Musk's xAI company, saying that the benchmark results of its latest AI model Grok3 were misleading. In response, xAI co-founder Igor Babushkin insisted that the company was not improper. The xAI chart shows that two versions of Grok3 - Grok3 Reasoning Beta and Grok3 mini Reasoning - outperformed OpenAI's current strongest available model, o3-mini-high, on AIME 2025. However, OpenAI employees were quick to point out on the X platform that the xAI chart does not include the o3-mini-high's AIME 2025 score under "cons@64" conditions. Babushkin argued on the X platform that OpenAI had published similar misleading benchmark charts in the past, even though they were used to compare the performance of its own models.
