Overview

• Apple is in early talks with Google on a custom Gemini model for Siri, and Google has begun training a version that can run on Apple’s own servers via Private Cloud Compute, according to Bloomberg.
• Inside Apple, two Siri tracks are being tested: Linwood using Apple’s models and Glenwood using external technology, with performance compared head‑to‑head.
• No partner has been selected, and Apple is targeting a 2026 launch for the overhauled assistant after a delay tied to engineering setbacks.
• Apple previously explored Anthropic and OpenAI for Siri, with Anthropic’s costs reported as a sticking point, while Apple also tests a first trillion‑parameter in‑house model.
• Shares of Apple and Alphabet rose after the report, as questions persist over pricing, data hosting and potential antitrust scrutiny given the companies’ existing search deal.
