--- title: "Apple smart glasses" seoTitle: "Apple smart glasses for developers: SDK, app model & distribution (2026)" description: "Apple smart glasses for third-party developers — SDK access, app model, distribution, capabilities & AI, and where it sits in the 2026 smart-glasses landscape." type: reference platform: all vendor: apple related: - /docs/ecosystem - /docs/ecosystem/openness - /docs/ecosystem/ai - /docs/ecosystem/distribution - /docs/vendors/meta - /docs/concepts/capabilities --- > **Openness verdict.** Closed by absence: as of July 2026 there is no shipping Apple glasses product and no glasses developer SDK. The only concrete developer surface is phone-side on-device AI — and that surface is real and increasingly open (Foundation Models, the new Core AI framework, MLX, and a first-party LoRA-adapter toolkit on iOS/iPadOS/macOS/visionOS), just not scoped to any glasses device. **Covered here:** Apple smart glasses. **Not covered here:** Apple Vision Pro · Rumored "Vision Air" · Camera-equipped AirPods (rumored, reported ~late-2027). ## Overview Apple has **not** shipped a smart-glasses product, and as of July 2026 has made **no official announcement** of one — nothing on the [Apple Newsroom](https://www.apple.com/newsroom/) or [Apple Developer](https://developer.apple.com/) site names a glasses device. Multiple press reports (Bloomberg's Mark Gurman, relayed via outlets such as [9to5Mac](https://9to5mac.com/2026/05/31/apple-glasses-launching-late-2027-with-vision-air-to-follow-by-2029/)) describe an internal program ("N50") aimed at an audio-and-camera AI accessory — cameras, mics, speakers, Siri/Apple Intelligence for interaction, **no on-lens display** in the first generation, iPhone-tethered — reportedly slipped to a **late-2027** launch. Treat all of that as unverified signal, not product. The closest in-class precedent is not Vision Pro but Apple's own audio accessories: reporting points to **camera-equipped AirPods** on a similar ~late-2027 window and the same audio-first + camera + Siri-visual-intelligence design ([MacRumors](https://www.macrumors.com/2026/06/16/airpods-camera-late-2027/)), and **AirPods Live Translation** (iOS 26, processed on-device on the paired iPhone) is the actual shipping pattern for an Apple audio accessory driving on-device Apple Intelligence ([Apple Support](https://support.apple.com/en-us/123185)) — the concrete template a glasses accessory would most plausibly inherit. The only Apple hardware in the adjacent MR space that actually ships is **Apple Vision Pro** (out of scope here — it is not glasses). Pricing, hardware spec, and ship date for any Apple glasses are unknown; the figures circulating point to a reported **~$200–$500 target**, which is analyst/rumor, not Apple. ## Access There is **no Apple glasses SDK** — no framework, package, or documentation for building glasses apps, because there is no device. What Apple does ship is a deep and increasingly open **phone-side on-device AI stack**, none of it glasses-scoped: (1) the [Foundation Models framework](https://developer.apple.com/documentation/FoundationModels) — a native **Swift** API giving direct access to the same on-device model that powers Apple Intelligence, **introduced at WWDC in June 2025** ([session 286](https://developer.apple.com/videos/play/wwdc2025/286/)) and made **available with iOS 26 / iPadOS 26 / macOS 26 / visionOS 26 in September 2025** ([Newsroom](https://www.apple.com/newsroom/2025/09/apples-foundation-models-framework-unlocks-new-intelligent-app-experiences/)), backed by **Private Cloud Compute** for heavier inference; (2) the new **Core AI framework**, announced at **WWDC26 (June 2026)** and shipping with the 2026 OS line — a memory-safe Swift API to load, specialize, and run **arbitrary** on-device models, 'everything from compact vision models to large-scale generative AI,' with ahead-of-time compilation and fine-grained inference/memory control, paired with a curated **Core AI Models** repo (Qwen, Mistral, SAM3) each convertible with one command via standard Python/PyTorch workflows ([What's new in ML](https://developer.apple.com/machine-learning/whats-new/), [session 324](https://developer.apple.com/videos/play/wwdc2026/324/)); and (3) **MLX**, Apple's open-source array framework for Apple silicon, which lets developers run and **fine-tune** arbitrary LLMs on-device via the MLX / MLX-LM Python packages (the mlx-community org hosts thousands of quantized models) ([opensource.apple.com](https://opensource.apple.com/projects/mlx/)). All of it is buildable in **Xcode** by anyone in the paid **Apple Developer Program** under the standard license agreement; models run on-device and offline. This is the substrate an eventual glasses accessory would most plausibly build on — but it is phone/Mac software, not a glasses platform. ## App model Undefined for glasses — no app model exists because no device or SDK ships. For the phone-side paths, code runs **natively in Swift** inside a standard iOS/iPadOS/macOS/visionOS app: Foundation Models runs the on-device model with optional escalation to **Private Cloud Compute**, while **Core AI** and **MLX** let an app load and run arbitrary on-device models with no server dependency and no token cost. There is no glasses runtime, no web-app layer, and no game-engine target. Apple has published no phone↔glasses transport, but it already ships the exact frameworks a phone-tethered Bluetooth accessory uses: **AccessorySetupKit** (iOS 18+, proximity-triggered secure pairing without broad Bluetooth scanning), the **ExternalAccessory** framework, and the **MFi Program** (Apple-licensed accessory protocol strings via `UISupportedExternalAccessoryProtocols`) ([AccessorySetupKit](https://developer.apple.com/documentation/accessorysetupkit/), [Accessories](https://developer.apple.com/accessories/)). A reported audio-first iPhone-companion accessory would almost certainly surface through these — MFi in particular is a genuine gating/reserved surface — though nothing glasses-specific is documented. The plausible shape is an iPhone-companion accessory (phone does the AI) rather than an on-device third-party app platform, but that is inference from reporting, not documentation. ## Distribution Not applicable to glasses — with no device and no SDK there is no distribution channel, no publishing path, and no review process for glasses apps. For context, Apple's general model is the **App Store** with mandatory App Review, and a licensed hardware accessory additionally routes through the **MFi Program** ([Accessories](https://developer.apple.com/accessories/)). A companion glasses accessory would most likely surface as features inside existing iPhone apps distributed through the App Store rather than as a separate storefront, but Apple has published nothing on this. Any developer/publishing timeline is unknown and gated on Apple first announcing hardware. ## Capabilities, limits & AI All glasses hardware capabilities are **unknown/unshipped**. Reporting (unverified) describes cameras, microphones, and speakers with **no on-lens display** in the first generation and Siri/audio as the primary interaction — but Apple has documented none of it, so camera access, mic/audio streaming, TTS/audio-out APIs, sensors, gesture input, and any reserved system surfaces are all undefined for third parties. **AI & the assistant:** there is no glasses assistant to open up. On the phone side, **Siri/Apple Intelligence is not a general third-party programmable assistant** — developers integrate via App Intents/Shortcuts and, for on-device generation, the [Foundation Models framework](https://developer.apple.com/documentation/FoundationModels), which supports **tool calling**, **guided (structured) generation**, and **streaming**, runs **on-device** and offline, and — as of WWDC26 — is materially more capable in glasses-relevant ways: it now accepts **multimodal prompts** (images alongside text), can call on-device **Vision tools** (OCR, barcode), supports **Dynamic Profiles** (swap models/tools/instructions at runtime), ships an **Evaluations** framework, and gives free **Private Cloud Compute** access to the latest server model for apps under 2M first-time downloads ([What's new in ML](https://developer.apple.com/machine-learning/whats-new/)). The BYO-model story is genuinely rich and mostly **first-party**: the **Foundation Models adapter training toolkit** lets you fine-tune Apple's own on-device model with your data via rank-32 **LoRA adapters** (~160MB each, loadable at runtime, with an optional speculative-decoding draft model) — the most glasses-relevant path, a small model specialized for an accessory's task ([adapter toolkit](https://developer.apple.com/apple-intelligence/foundation-models-adapter/)); the new **Core AI** framework and **MLX** let you load, run, and fine-tune arbitrary open models on-device; and a third-party provider layer lets other LLM vendors plug in, with **Anthropic (Claude)** and **Google (Gemini)** packages announced/upcoming ([WWDC26 session 339](https://developer.apple.com/videos/play/wwdc2026/339/)). Apple's own [next-generation Apple Intelligence](https://www.apple.com/newsroom/2026/06/apple-intelligence-brings-powerful-ai-capabilities-into-everyday-experiences/) uses Google Gemini for server-side tasks. Voice invocation of custom logic goes through Siri/App Intents, not a raw wake-word API. None of these AI hooks are exposed on or scoped to a glasses device today. ## Roadmap **Shipped/dated (primary):** Foundation Models framework introduced at **WWDC June 2025** ([session 286](https://developer.apple.com/videos/play/wwdc2025/286/)), available with iOS/iPadOS/macOS 26 in **September 2025**; at **WWDC26 (June 2026)** Apple announced the **Core AI** framework for running arbitrary on-device models, expanded Foundation Models to multimodal + Dynamic Profiles + Evaluations + free PCC under 2M downloads, and surfaced a third-party provider layer (Claude/Gemini packages announced/upcoming, [session 339](https://developer.apple.com/videos/play/wwdc2026/339/)); next-generation Apple Intelligence + a more capable Siri, built with Google Gemini for server tasks, detailed [June 2026](https://www.apple.com/newsroom/2026/06/apple-intelligence-brings-powerful-ai-capabilities-into-everyday-experiences/). **Glasses (reported, not announced):** press reporting through 2026 (Gurman/Bloomberg via outlets like [AppleInsider](https://appleinsider.com/articles/26/05/31/longtime-leaker-joins-others-in-saying-apple-glasses-wont-arrive-until-late-2027) and [9to5Mac](https://9to5mac.com/2026/05/31/apple-glasses-launching-late-2027-with-vision-air-to-follow-by-2029/)) points to a **late-2027** launch for an audio-first "N50" accessory, delayed to let Apple's visual AI mature, with a lighter "Vision Air" headset reportedly ~2029. **Momentum:** heavy, accelerating investment in the on-device AI substrate (Foundation Models → Core AI → MLX → the adapter toolkit — the likely foundation for any future glasses), but **zero official glasses hardware or SDK signal** — no announced device, no developer preview, no dated SDK. Extentos will add an Apple glasses transport if and when Apple ships an actual SDK; until then there is nothing to target. ## In the landscape Apple smart glasses is one platform in the third-party [smart-glasses landscape](/docs/ecosystem).
