Apple Wants ChatGPT-Like Intelligence for Siri, Could Use Private Cloud Hosting

Apple’s exploration of using AI models from OpenAI or Anthropic to power Siri is reportedly part of a broader effort to revitalize its lagging AI initiatives. According to Bloomberg’s Mark Gurman, the company is considering sidelining its own in-house models in favor of external solutions—a major strategic shift intended to boost Siri’s capabilities.

This move has sparked internal tension, leading to the recent departure of senior AI engineer Tom Gunter. Additionally, the team behind Apple’s MLX open-source AI framework has allegedly threatened to quit, expressing frustration over the company’s current direction in AI development.

Despite considering partnerships with OpenAI and Anthropic, Apple has not entirely abandoned its in-house AI efforts. The company continues to work on “LLM Siri,” a project aimed at redesigning Siri using Apple’s own large language models by 2025. However, top executives reportedly believe that integrating third-party AI may be essential to closing the gap with rivals like Google and OpenAI, who have taken the lead in consumer-facing AI products.

Apple’s pivot away from building some in-house models began earlier this year when it canceled its own coding LLMs, originally planned as part of Swift Assist. Instead, Apple now enables developers to access external AI tools like ChatGPT and Anthropic’s Claude directly within Xcode, and it has started using Claude internally for code generation tasks. This reflects a broader shift in Apple’s AI strategy—one that prioritizes immediate capabilities over building every tool in-house.

At the same time, Apple is grappling with growing challenges in retaining top AI talent. According to Mark Gurman, engineers are being lured away by rivals like Meta and OpenAI with offers reportedly more than double Apple’s compensation. Meta, for instance, just launched the Meta Superintelligence Labs to pursue artificial general intelligence (AGI), hiring leading researchers from across the industry. Meanwhile, Apple is planning a significant Siri overhaul for iOS 26.4 in 2026, aiming to make the assistant more context-aware and capable of executing complex tasks based on on-screen content and personal data.
