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.

After failing to release its AI-powered Siri last year, Apple needs to do some major surgery on its voice assistant ASAP.

The iPhone maker has talked with both companies about using their large language models for Siri, according to sources.
