Tesla chief Elon Musk has said he would ban Apple devices at his companies if Apple integrates OpenAI at the operating system level. In a posting on X he said it would constitute an ‘unacceptable security violation’.

Apple has this week announced several generative AI products and services, including a plan to integrate ChatGPT into its devices and work with OpenAI.

Musk also said that visitors would have to check their Apple devices at the door with them then being held in Faraday cages.

Musk, who co-founded OpenAI in 2015, now runs a rival firm called xAI and has been involved with legal wrangles with OpenAI. He is suing OpenAI and its CEO for allegedly breaching OpenAI’s founding agreement and diverging from its nonprofit mission.
