Will Apple’s collaboration with OpenAI and Anthropic make Siri smarter?

Once seen as the weakest link in Apple’s ecosystem, Siri is finally catching up. And it’s not because Apple built a revolutionary new brain in-house — it’s because they are likely to make a deal with two of the most powerful AI companies in the world: OpenAI and Anthropic.

Apple’s revamped Siri, launching with iOS 18, taps into the power of GPT-4o and Claude when tasks go beyond what its own Apple Intelligence system can handle. Think rewriting text, analyzing images, or summarising documents — jobs where LLMs shine.

And for the first time, she’ll have access to some of the most advanced generative AI models available — including GPT‑4o from OpenAI and Claude from Anthropic.

But this partnership isn’t just about raw power. It’s about bringing the best of AI to users in a way that’s seamless, intuitive, and private.

A smarter, more capable Siri

With this update, Siri now supports richer language understanding, improved memory across context, and the ability to interact with apps more naturally. She can rewrite messages, summarise long documents, and even understand images — all using natural language.

When tasks go beyond the capabilities of Apple’s on-device intelligence, Siri can now tap into OpenAI’s GPT‑4o — a powerful, multimodal model — or Anthropic’s Claude, a safety-first AI trained for complex reasoning. Users are always asked for permission before these models are accessed, and results are returned in seconds, without compromising on privacy.

“This is a major leap forward for Siri,” said Craig Federighi, Apple’s senior vice president of Software Engineering. “By combining Apple’s deep integration and privacy standards with the intelligence of trusted AI partners, we’re unlocking powerful new ways to get things done — while keeping users in control.”

Privacy at the core

Apple’s approach to AI is grounded in a simple principle: users should never have to trade personal data for intelligence.

When Siri calls on GPT‑4o or Claude, it uses Private Cloud Compute — Apple’s secure server architecture that processes requests without storing personal information. Data is encrypted, used only for the duration of the request, and never shared or retained. Independent experts can inspect the code running on Apple’s AI servers to verify privacy standards.

It’s AI, done the Apple way.

Built-in optionality

Users can choose which model they prefer, and Apple plans to expand support for other AI models over time — offering flexibility while keeping user experience and safety consistent.

This hybrid approach — combining powerful on-device AI with optional, best-in-class models in the cloud — gives Apple a unique edge. It enables fast, secure intelligence for everyday tasks, while unlocking even more capabilities when needed.

Apple Intelligence and the new Siri experience will begin rolling out in beta this fall, starting with U. English.

Looking ahead

With this next chapter, Siri isn’t just catching up — she’s leading with a new voice, a deeper understanding of context, and the intelligence to help users do more than ever before.
