At WWDC 2026 (06-08) Apple shipped Siri AI on Apple Foundation Models "custom-built in collaboration with Google and its Gemini models" (Apple's own wording), partly hosted on Google's cloud on Nvidia Blackwell GPUs under Private Cloud Compute. Deal terms remain unconfirmed by either company (~$1B/yr is reporter-sourced only, never officially stated). The real regulatory angle is the EU: Apple withheld Siri AI from EU iPhones at launch (06-09) citing DMA compliance after the EU rejected its exemption request — not US antitrust. Track: EU launch resolution, whether the $1B/yr figure ever gets confirmed, whether Apple builds back toward its own frontier model. # crawl 2026-07-27
