Apple Plans Siri Overhaul Into Built-In Chatbot for iOS 27, Reports Say

Apple is pivoting to Google-backed foundation models as it phases in the redesign across 2026.

Overview

  • Bloomberg reports Apple will replace the current Siri interface with a conversational chatbot, code-named Campos, embedded across iPhone, iPad and Mac with both voice and text input.
  • The staged rollout reportedly starts with an iOS 26.4 update this spring using Apple Foundation Models v10 on Private Cloud Compute, followed by a WWDC preview in June and a full release with iOS 27 in September.
  • Apple and Google have confirmed a multi-year collaboration under which Apple’s next foundation models are based on Gemini, and outlets report Apple is paying roughly $1 billion annually for model access.
  • The revamped assistant is expected to handle web search, content and image generation, summarization, file analysis, on-screen awareness, and deep control of core apps and system settings.
  • Technical reporting says AFM v10 runs at about 1.2 trillion parameters, with a higher-end AFM v11 comparable to Gemini 3 planned for Campos, and Apple is weighing privacy limits on conversational memory and potential hosting on Google TPUs.
