Apple may switch Siri to Claude AI

Apple is considering moving its voice assistant Siri to Claude, the artificial intelligence model developed by Anthropic, Bloomberg reports, citing sources familiar with the matter.

Following a series of internal tests, Apple executives found Anthropic’s Claude technology to be the most suitable for Siri’s upcoming features. The company had previously evaluated models from OpenAI and Google, but ultimately favored Anthropic.

According to Bloomberg, Apple has already approached both Anthropic and OpenAI with proposals to develop custom versions of their AI models for Siri. These models would run on Apple’s own cloud infrastructure. If the negotiations lead to an agreement, it would mark a departure from Apple’s previous strategy, which has largely relied on in-house models.

An updated version of Siri was initially planned for early 2025, but the launch has since been pushed back — with the rollout now expected no earlier than 2026. Bloomberg’s sources note that Apple has yet to make a final decision on whether the new Siri will be powered by third-party models or the company’s proprietary technology: the internal LLM Siri project, built on Apple Foundation Models, is still in active development.

The push to explore external AI options came from Mike Rockwell, head of Siri, and Craig Federighi, senior vice president of software engineering. After the departure of John Giannandrea, who previously oversaw Apple’s AI efforts, Rockwell and Federighi were tasked with accelerating Siri’s modernization. Upon joining the Siri team in March 2025, Rockwell immediately initiated a comparison of Claude, ChatGPT, and Google Gemini. Claude delivered the most promising results — prompting Apple VP Adrian Perica to begin partnership talks with Anthropic.
