If Apple follows suit, OpenAI or Anthropic could lock in another blue-chip customer, pushing both further ahead in the AI arms race. More importantly, Siri’s long-awaited glow-up might actually deliver this time.

Apple software chief Craig Federighi announced that the company will allow third-party developers to use its core AI model. This will help them create apps that focus on privacy. Apple will also provide code completion options from both its own tools and OpenAI's in its main developer software.

For months, Apple has been working to get its AI-enhanced Siri back on track after delaying the overhauled assistant’s launch in March. Apple later appointed Vision Pro head Mike Rockwell as the leader of AI and Siri after CEO Tim Cook “lost confidence” in the team’s former chief, John Giannandrea.
