Apple to use Google’s Gemini AI for $1b Siri upgrade: sources

Apple is in final talks to use Google’s Gemini AI model to upgrade the Siri voice assistant, with a launch expected in spring 2026, sources told Bloomberg.

The deal would see Apple pay about US$1 billion annually for access to Gemini, a model with 1.2 trillion parameters, far more than Apple’s current cloud-based AI, which uses a 150 billion parameter system.

Gemini would support Siri’s summarizer and planner features, while some Siri functions will still use Apple’s own models.

The AI will run on Apple’s Private Cloud Compute servers, keeping user data separate from Google infrastructure.

Apple chose Gemini after evaluating models from OpenAI and Anthropic.

The partnership will remain largely behind the scenes, unlike Apple’s public deal with Google Search.

Apple aims to eventually replace Gemini with its own model, which is in development and could be ready in 2026.

🧠 Food for thought

Implications, context, and why it matters.

Apple’s Private Cloud Compute may face scale challenges with Gemini

Private Cloud Compute (PCC), Apple’s privacy-focused Siri cloud, runs on custom Apple silicon servers using M2 Ultra and the internal “ComputeModule14,1” board 1. Bloomberg puts Apple’s current cloud model near 150 billion parameters. Gemini sits near 1.2 trillion, about 8 times larger, which drives higher memory and compute needs than Apple’s setup today.
The design uses stateless computation plus cryptographic safeguards 2. Requests process ephemerally, and the system deletes keys on reboot so data stays unrecoverable. These choices curb cross‑session caches, which can lift latency and cost with a larger model.
Bloomberg cites about $1 billion per year to Google for Gemini access. Apple has not said if it includes infrastructure. Apple says Gemini‑powered Siri will run on PCC, not on Google systems, to keep data separate. Meeting Siri latency with PCC’s privacy rules may need more Apple silicon servers 2.

App developers can capture Siri demand by building robust App Intents ahead of the spring 2026 launch

Siri’s planner and summarizer arrive in spring 2026. Apps that ship clear App Intents should get called more as Siri performs tasks in apps 3. App Intents is Apple’s framework that exposes actions plus data to Siri and links to Shortcuts.
Tool makers or SaaS platforms can sell Siri‑ready SDKs with guides that help teams expose features via App Intents before rivals move 4 5.
Apple is testing with large companies first, with early limits on sensitive categories 3. Business-to-business (B2B) software in productivity, commerce, and non‑banking financial services should build App Intents to be ready for broader rollout.
