Can Siri Use Claude or ChatGPT? Price and Access
Apple code shows Siri routing to Claude or ChatGPT, but public access and billing are absent. Compare current official model and plan prices.

AI Pricing Guru articles are maintained by the editorial workflow behind the site: daily pricing snapshots, provider source checks, and review passes for model launches, subscription limits, and billing changes.
TL;DR
- Private iOS 27 and macOS 27 frameworks let a demonstrated Claude extension handle requests through Siri and hand Apple-system actions back to Siri.
- A second private mechanism replaced Siri's server model with GPT-5.6 Terra while preserving Siri's interface, voice, planner, and tool access.
- This is not a public Claude-for-Siri launch: ChatGPT is the only supported 'Ask...' extension in the macOS release candidate, and Apple has not opened the required entitlements.
- No Siri fee, subscription change, or API rate change was announced. Do not buy a Claude or ChatGPT plan for this capability until Apple explains access and billing.
Current consumer plans—none confirmed as a Siri requirement
| Plan | Current price | Tier | Published limits and access |
|---|---|---|---|
| ChatGPT Free | $0 | free | GPT-5.6 Terra is available to Free users; subscription prices and quota budgets were unchanged by the July 30 price cut. |
| ChatGPT Plus | $20/mo | pro | Plus users can choose GPT-5.6 Terra and Luna; subscription prices and quota budgets were unchanged by the July 30 price cut. |
| Claude Free | $0 | free | Limited Sonnet access, resets every 5 hours |
| Claude Pro | $20/mo | pro | Approx 5x Free, priority during peak, extended context. Claude Fable 5 access continues via usage credits beginning July 20, 2026, with a one-time $100 Fable credit. |

Apple has built private Siri hooks that can send work to Claude or replace Siri’s server-side model with ChatGPT, according to code demonstrations published September 13. The architecture could eventually turn Siri into a model-neutral assistant, but the discovery is evidence of technical capability—not a product announcement.
The pricing consequence today is no change. Apple, Anthropic, and OpenAI have not announced public Claude access in Siri, a new Siri AI charge, a required paid plan, or a billing method for third-party inference. The live subscription and API tables on this page show current standalone prices; they are comparison references, not confirmed Siri requirements.
What the Siri code shows
Researcher pdfu demonstrated two separate integration paths found in iOS 27 and macOS Golden Gate private frameworks.
The first uses Apple’s Model Delegation API in App Intents. Claude appears in Siri’s “Ask…” menu like the existing ChatGPT extension. In the demonstration, Claude creates a CSV itself. When asked to set a reminder, it interprets the request and relays it to Siri, which performs the Apple-system action.
The second path goes deeper. An Inference Providing protocol in Model Manager Services lets an app extension replace Apple’s server-side Siri model. The demonstration routes the request to GPT-5.6 Terra, which receives Apple’s planner prompt and tool definitions, calls Apple tools, receives results containing personal data, and returns an answer through Siri’s interface and voice. The test’s requests also appear in OpenAI’s platform log.
| Siri integration path | What the demonstration did | Public status on September 14 |
|---|---|---|
| Siri “Ask…” extension | Claude answered requests and handed system actions back to Siri | Claude requires a private entitlement |
| Server-model replacement | GPT-5.6 Terra used Siri’s planner and tools behind Siri’s UI | Private extension point; not user-facing |
| Supported release-candidate route | ChatGPT appears in the “Ask…” flow | ChatGPT only in the macOS 27 release candidate |
Can you choose Claude in Siri now?
No. The Claude demonstration requires the private com.apple.developer.model-delegation entitlement. Apple has not opened that entitlement to third-party developers, and Claude does not appear as a supported public choice.
The full server replacement uses the private com.apple.modelmanager.inferenceprovider extension point. Code present in an operating system can support internal testing, partners, regulatory preparation, or a future release without ever becoming a general developer feature. There is no launch date.
Apple’s public documentation covers adjacent capabilities: a ChatGPT extension for Apple Intelligence, App Intents that expose app actions to Siri, and a Language Model protocol for using cloud models inside apps. It does not publish either private replacement mechanism as a generally available developer feature.
Pricing impact: unchanged today, unknown later
No provider published a new price alongside this discovery. The live tables compare current standalone ChatGPT and Claude plans and direct developer rates for the named model families. They should not be read as a Siri rate card.
The OpenAI platform log in the server-replacement demo suggests the test reached an external provider account. It does not establish whether a public version would be included with Apple Intelligence, linked to a consumer subscription, billed to a developer API account, or funded through an Apple-provider agreement.
That distinction could materially change the cost. A bundled route would feel like a device feature; bring-your-own subscription access would favor people already paying for a provider; API billing would make long conversations, large email summaries, and repeated tool loops usage-sensitive. Until Apple documents the route, any monthly Siri cost estimate is speculation.

Who benefits—and who may pay more
Users gain choice if Apple ships both paths. Claude could handle document creation or other requests outside Siri’s native abilities, while Siri retains system actions and its familiar interface. People could select a model based on trust, capability, or an existing account instead of accepting one default.
Anthropic gains distribution because Siri could place Claude at an operating-system entry point already occupied by ChatGPT. OpenAI faces more visible competition, although the deeper GPT-5.6 demonstration also shows how closely its models could integrate with Apple’s planner and tools.
The risk sits with privacy and unpredictable usage. A third-party model may receive planner instructions, tool outputs, email content, contacts, and other personal data needed to complete a request. Users and enterprise administrators will need clear consent, data-retention terms, account boundaries, audit logs, and spending controls before enabling such a route.
What users and developers should do
Do not subscribe to Claude or upgrade ChatGPT solely for Siri integration. Wait for Apple to confirm supported providers, devices, regions, authentication, privacy terms, quotas, and who pays for inference.
Developers should treat the private hooks as a direction signal, not a production API. Keep model calls provider-neutral, separate Apple tool permissions from model selection, minimize personal data sent off-device, and track cost per completed task. If Apple opens the framework, test the same Siri workflows across providers before choosing a default.
AI Pricing Guru Labs already measures the underlying models through ordinary text endpoints. The private Siri route remains an explicit route-and-availability blocker until Apple exposes a callable path, stable model contract, repeatable tool permissions, token ledger, and actual billing terms.
The important shift is architectural: Siri may be designed to broker between Apple tools and competing models. The commercial model—bundled, subscription-linked, API-metered, or partner-funded—remains the unanswered question.
