## What is On Device?

On Device LLM — локальная AI-студия для iPhone. Языковые и визуальные модели с открытым кодом работают полностью на устройстве через MLX от Apple — без серверов, API-ключей, телеметрии и аккаунтов.

ЖИВЫЕ ПОДПИСИ К КАМЕРЕ
Наведите камеру на что угодно. SmolVLM описывает сцену каждые несколько секунд, выводя подпись прямо в видоискатель.

ГОЛОСОВОЙ ДИАЛОГ
Hands-free чат с on-device LLM. Детектор голосовой активности игнорирует фоновый шум; ответы озвучиваются в той же аудиосессии.

## Version history (last 5 releases)

### 3.2.3 — 2026-07-24

Turn your iPhone into a private local AI server for computers on your network.

NEW
• OpenAI-compatible chat completions and model-list endpoints.
• Ollama-compatible chat, generate, and model-list endpoints.
• A configurable LAN server port with copyable connection URLs.
• Bearer-key authentication with secure key storage, reveal, copy, and rotation controls.
• Streaming and non-streaming responses using the language model already loaded on your device.
• Linux-friendly setup instructions and ready-to-copy curl examples.

IMPROVED
• The Mac Bridge remains available with its existing encrypted pairing workflow.
• Clearer server status, network-address handling, lifecycle behavior, and error messages.

The local API server is disabled by default and intended for trusted networks while the app is in the foreground.

### 3.2.2 — 2026-07-17

Lens now feels more at home on iPhone.

NEW
• Added support for the Bonsai 8B and 27B EXT series for more capable on-device assistance.
• A redesigned Liquid Glass Lens experience keeps the camera front and center.
• A compact model picker makes on-device readiness easier to understand.
• Ask, Translate, Scan, and Solve now have clearer modes and subtle visual accents.
• New capture, scanning, and result animations provide better processing feedback.
• Lens answers are easier to read, with improved hierarchy and streamlined actions.
• Accessibility improvements include larger controls, Dynamic Type, VoiceOver labels, Reduce Motion, and increased-contrast support.


Everything continues to run entirely on your device — no account, no servers.

### 3.2.1 — 2026-07-13

A fresh, brighter interface for both Light and Dark Mode.

• New Liquid Glass surfaces on iOS 26 and later
• Cleaner backgrounds with improved contrast and readability

More stable, private, and dependable on-device AI.

NEW
• Safer Wipe All Data — clears saved API keys, Hugging Face token, and Mac Bridge pairings from Keychain.
• Stronger Mac Bridge pairing protection and safer web page fetching.
• Conversation saves now report failures instead of failing silently.
• iCloud sync entitlement and clearer sync error reporting.

VOICE
• KittenTTS speaks with less lag between sentences.
• Apple System Voice prefers Enhanced/Premium voices and avoids the Bluetooth “zombie” route after voice chat.
• Kokoro float16 audio decoding fixed (download Kokoro from Models → Catalog to enable).

LENS
• Fixed a camera vision-encoder crash (SIGSEGV) on newer iPhones by keeping Core ML off the GPU path.

Everything still runs entirely on your device — no account, no servers, nothing ever leaves your iPhone.

• Lower camera preview frame rate and stronger thermal backoff when iPhone reports serious heat.
• Live OCR now runs less often and prevents overlapping recognition work.

• Continued model, voice, and stability fixes.

Everything still runs entirely on your device — no account, no servers, nothing ever leaves your iPhone.
