Siri AI Will Have Deep Integration With ChatGPT and Claude Models, Leaked Build Shows

Apple's upcoming iOS 27 and MacOS Golden Gate updates will allow Siri to deeply integrate with third-party AI models like OpenAI's ChatGPT and Anthropic's Claude. Users may even replace Siri's AI with other large language models such as GPT-5.6, enabling enhanced on-device AI capabilities and cross-platform access to personal data through these models. This move aligns with EU regulations requiring broader third-party AI access.
