Apple Inc. is considering using artificial intelligence technology from Anthropic PBC or OpenAI to power a new version of Siri, sidelining its own in-house models in a potentially blockbuster move aimed at turning around its flailing AI effort.

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.

As part of this proposed new plan, Apple has asked Anthropic and OpenAI to train versions of its models that can run on Apple's Private Cloud Compute, secure servers running on Apple chips. The company already relies on its servers for certain AI features that can't be run locally.
