Hey hunters 👋

Hunting this because yesterday Apple did something it has never done in 49 years: it let you choose someone else's AI as your iPhone's brain.

Quick context for anyone who missed the keynote — this was Tim Cook's last one as CEO (John Ternus takes over September 1), and it came after two years of delayed Siri promises and a $250M settlement over AI features Apple advertised but never shipped. Here's what they actually delivered:

🧠 A complete rebuild

Chatbot-style interface like ChatGPT/Claude, a standalone Siri app, and a system-wide "Search or Ask" gesture. Under the hood: a custom 1.2-trillion-parameter Gemini model Apple licenses from Google for a reported ~$1B/year (confirmed on stage).

🔀 Extensions — the real headline

For the first time, you pick which model powers Apple Intelligence: ChatGPT, Gemini (default), or Claude. Each responds with its own distinct voice so you always know which AI answered. Across ~2.2 billion active Apple devices, this is the biggest AI distribution decision ever made.

🤖 The full model stack (per Apple's developer docs)

• Siri's brain: custom 1.2T-param Gemini running on Apple's Private Cloud Compute — not Google's servers

• Your pick via Extensions: Gemini, ChatGPT, or Claude

• On-device: Apple's own foundation models — private, offline, and now open to every app via the Foundation Models framework in just 3 lines of Swift

• Devs under 2M downloads get Private Cloud Compute access for FREE — and the same Swift API can call Claude or Gemini server-side

🔒 The privacy twist

Heavy Gemini reasoning runs on Apple's own Private Cloud Compute servers — not Google's infrastructure. Apple controls what data leaves the device; personal tasks stay on-device entirely.

📱 Personal context + on-screen awareness

Siri can use your emails, photos, messages, calendar, and files, see what's on screen, and take cross-app actions. Plus visual intelligence: search and act on anything on your screen or through the camera. The stuff demoed in 2024 — actually shipping this time.

⚙️ The fine print

iOS 27 Beta 1 is out now for developers. Public release this fall. Apple Intelligence needs iPhone 15 Pro or newer; iPhone 11 got dropped from iOS 27 entirely.

So — the question 2 billion people will answer in Settings this September:

ChatGPT, Gemini, or Claude. Which one becomes your Siri, and why? 👇
