Apple opened Siri AI to every developer on November 3, and in the same breath confirmed something iPhone owners should pay attention to: the server-powered parts of Siri will carry daily usage limits, and getting more will eventually cost money. The two announcements landed a day apart, and together they describe what Siri becomes next, an assistant that works inside any app, on a meter.
The developer opening arrived with the first iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas. Until now, Siri AI could act inside a third-party app only when the task fit one of the categories Apple had defined in advance. The new Developer Preview removes that template requirement. Any app can now bring its own content and actions directly into Siri AI using App Intents, the framework apps already use for Shortcuts, Spotlight and widgets.
App Intents turns any app action into a Siri tool
The mechanism is deliberately simple. A developer marks an intent with a Swift macro, @AppIntent(.tool), which makes it conform to a new ToolIntent protocol and exposes it to Siri as a tool the assistant can call. Apple says the integration gives Siri access to its newest capabilities, including personal context understanding, onscreen awareness and natural language. Its own examples run from checking a delivery to booking a reservation to placing an order.
Apple also introduced app skills, written as SKILL.md files, which teach Siri AI how to string several of those actions together into one job. And Siri can now surface anything in the Spotlight semantic index, not just items that match Apple’s schemas. There is no new entitlement to apply for and no separate developer program to join, which lowers the barrier for small developers as much as for big ones.
There is a catch on timing, and it is a long one. The preview is build-and-test only. Integrations work in developer-signed builds and with internal TestFlight testers, but not with external TestFlight testers and not in App Store versions of apps, even when those apps already contain the new code. Apple says the first customer release arrives in a few months, and App Store submissions for apps with Siri AI integrations open in the spring. Apple has also not yet published the terms and usage policies that will govern what developers build, and it warns that the App Intents API and Siri’s behavior may change during the preview.
Daily limits are confirmed, prices are not
The second half of the story is the meter. Apple’s support page on Apple Intelligence usage limits, published September 9, states that features relying on server-side models will be subject to usage limits, and that “increased access to such features will be available for a fee.” On the November 2 earnings call, Apple CEO John Ternus confirmed the plan in plainer terms: certain features that rely on server-side AI models, including Siri AI and intelligent photo editing, will have usage limits, and customers who need more capacity will eventually be able to buy expanded access.
What Apple has not said matters as much as what it has. There is no number for the daily allowance, no reset time, no price for expanded access, and no date for when the paid option appears. The support page says a feature that hits its limit becomes available again after a time-out period, and that limits may vary by feature, request complexity, system demand and system policies. Developer documentation is blunter: exceeding the daily quota means waiting for a refresh or upgrading.
One distinction is worth holding on to. Work that runs entirely on the device is not expected to be covered by these limits. Apple’s developer documentation says the on-device model has no usage limit, while the cloud model has a daily limit. That makes the split between on-device and server-side processing the most important technical detail in Siri’s future, and it is the reason Apple keeps stressing on-device efficiency on earnings calls. Siri already handles more than 2.5 billion requests a day, according to the company, so even a small fraction of those moving to paid server capacity is a large business.
Who gets Siri AI, and who still waits
Siri AI needs an Apple Intelligence-enabled device set to a supported language. The current list is English, French, Japanese, Korean, Portuguese and Spanish, with Traditional Chinese, Norwegian, Turkish and Vietnamese coming in the beta. It is unavailable to users under 13.
The European Union remains the conspicuous gap. Siri AI is still unavailable in the EU on iOS, iPadOS and watchOS, though it is available on macOS and Vision Pro there, and Apple says it is working with EU regulators on a path to availability. That split means the developer preview’s most enthusiastic early testers may be building for an audience that cannot yet use the result on an iPhone.
Apple is using the gap before launch to recruit developers. It is running Apple Intelligence Group Labs on November 4 and 5 to answer implementation questions, and the spring App Store opening gives developers months to build before customers arrive. The question that will decide whether this opening matters is not whether developers show up. It is whether Apple prices the meter gently enough that users keep asking Siri to do things inside other people’s apps, and whether the terms it publishes leave room for the small developers it just invited in. For now, the answers are “in a few months” and “soon,” which is Apple for “wait.”
