Musk's ketamine use can't be probed in OpenAI trial: US judge

Billionaire Elon Musk's use of the drug ketamine will be off-limits to attorneys for OpenAI and its CEO, Sam Altman, during an upcoming jury trial, US District Judge Yvonne Gonzalez Rogers ruled. The trial centres on claims that the generative AI company defrauded Musk by abandoning its nonprofit roots. The decision was made at a hearing in California on Friday.
