At its Worldwide Developers Conference on June 10, Apple announced a late but major move into AI with “Apple Intelligence,” confirming months-long rumors that it would partner with OpenAI to bring ChatGPT to iPhones.

Elon Musk, one of the cofounders of OpenAI, was quick to respond on X, branding ChatGPT-powered Apple AI tools “creepy spyware” and an “unacceptable security violation.”

“If Apple integrates OpenAI at the OS level, then Apple devices will be banned at my companies,” Musk wrote.
