A leaked software build suggests Apple is preparing to give Siri unprecedented access to external large language models, including ChatGPT from OpenAI and Claude from Anthropic. The discovery points to a major expansion of Siri's capabilities beyond Apple's own on-device intelligence.

What You Need to Know

The integration would let Siri process complex queries by routing them to ChatGPT or Claude, rather than relying solely on Apple's own AI. This marks a strategic shift toward partnering with outside AI providers. Users could see more natural, context-aware conversations with Siri, but privacy and data handling questions remain unanswered. The leaked build does not indicate a release date, but code suggests the feature is in active testing.

The Leak and Its Implications

According to internal files found in a pre-release version of Apple's operating system, Siri AI will include direct hooks to ChatGPT and Claude models. The code references API endpoints and authentication methods tailored to each service. This goes beyond simple web search integration, suggesting Siri could hand off entire conversations to the third-party models and relay responses back to the user.

The leaked build shows that Apple is building a framework that lets Siri decide when to use its own neural engine versus calling on ChatGPT or Claude. Early indications suggest the system will prioritize Apple's on-device processing for simple commands and reserve the external models for tasks requiring broader knowledge or creative generation.

  • ChatGPT integration: Would enable Siri to generate human-like text, answer follow-ups and maintain conversation context.
  • Claude models access: Could provide nuanced reasoning and safer content filtering for sensitive queries.
  • Local AI fallback: Apple's own smaller models would handle quick requests like timers or music playback without sending data externally.

Why This Matters

Apple has long kept Siri tightly controlled, relying on its own technology. Opening the assistant to models like ChatGPT and Claude represents a philosophical shift that could redefine user expectations. Competitors such as Google and Samsung already offer generative AI features on their devices, and Apple has faced criticism that Siri has fallen behind. This integration would let Apple catch up without having to build a competing foundation model from scratch.

Privacy is the central tension. Apple has marketed Siri as privacy-first with on-device processing. Relying on external AI services means user data could leave the device. Apple will likely need to implement strict anonymization and opt-in consent mechanisms. How the company handles this could determine whether users trust the new capabilities or avoid them.

What This Means for Users

If implemented, the change would make Siri far more capable. Tasks that currently stump the assistant, such as writing a detailed email, summarizing documents or holding a flowing conversation, could become routine. Developers would also gain access to new APIs, allowing third-party apps to tap into Siri's expanded intelligence.

The leaked build does not reveal pricing or subscription tiers. ChatGPT and Claude both offer free and paid plans, and Apple might bundle access into an existing service like iCloud+ or offer standalone subscriptions. The competitive landscape suggests Apple will move quickly, possibly announcing a timeline at its Worldwide Developers Conference later this year.
