Apple is exploring using OpenAI or Anthropic's large language models to improve Siri, following delays and concerns about its in-house AI development. Bloomberg reports that Apple's Vision Pro head, Mike Rockwell, tested Anthropic's Claude, OpenAI's ChatGPT, and Google's Gemini, with Claude showing the most promise. These efforts are in early stages, and Apple may still opt for its own models. The upgraded Siri was notably absent from Apple's recent developer conference, highlighting ongoing challenges in its development.
