Former OpenAI Chief Technology Officer Mira Murati testified under oath that CEO Sam Altman made false statements to her regarding safety standards for a new artificial intelligence model, according to a video deposition shown in court Wednesday.

The testimony was presented during the ongoing legal case between Elon Musk and Altman. In her deposition, Murati stated that Altman incorrectly told her that OpenAI's legal department had determined that a new AI model met necessary safety requirements.

Murati, who previously served as OpenAI's CTO before departing the company, provided the testimony as part of the legal proceedings. The deposition represents sworn testimony given under penalty of perjury.

The testimony comes amid broader scrutiny of AI safety practices at major technology companies developing advanced AI systems. OpenAI has been at the center of discussions about responsible AI development and deployment standards.

The legal dispute between Musk, a co-founder of OpenAI, and Altman involves claims about the company's direction and governance. Musk has previously raised concerns about OpenAI's transformation from a nonprofit research organization to a commercial entity.

Neither OpenAI nor Altman immediately responded to requests for comment regarding Murati's testimony.
