LLM Server

Your Phone Is Now an AI Server

LLM Server turns your iPhone or iPad into a private AI inference server. Run large language models entirely on-device, expose an OpenAI-compatible API to your local network, and chat with your model from any browser on any device — laptop, desktop, tablet, even another phone. No cloud, no subscription, no data leaving your hardware.

Chat From Any Browser on Your Network

Start the server and open the URL on any device sharing your Wi-Fi. The built-in web interface gives you a clean chat UI instantly — no client app to install, no account to create. Your laptop, your partner's tablet, a colleague's machine: all talking to a model running on your phone.

OpenAI-Compatible API, Drop-In Ready

A standard OpenAI-compatible API means LLM Server slots into any tool you already use — Continue, Open WebUI, LangChain, custom scripts, the lot. Chat completions, text completions, streaming (SSE), and model listing endpoints all supported. Ollama CLI commands work too.

Fully Offline, Fully Yours

- Download a GGUF model once and you're done with the cloud. Inference runs locally on Apple Metal GPU with no internet required. Your prompts, your conversations, your data — none of it leaves the device. Airplane mode works fine.

Any GGUF Model From Hugging Face

- Browse and download directly from Hugging Face with built-in search, or import your own files. LLaMA, Mistral, Phi, Gemma, Qwen, DeepSeek, and every other llama.cpp-supported architecture runs out of the box. Background downloads with progress tracking so you can keep working.

Enterprise-Grade Security

- TLS/HTTPS encryption — generate self-signed certificates or import your own chain and private key.

- API key authentication — Bearer tokens with per-key management. Generate cryptographically secure keys or bring your own.

- Bind control — lock to localhost, open to your LAN, or pin to a specific interface.

Tune Every Knob

Full control over generation: context size up to 32K, temperature, top-p, top-k, repeat penalty, frequency and presence penalties, max tokens, seed, GPU layer offloading, and thread count. Save presets globally or per model.

Smart Resource Management

Your phone stays responsive under load. Real-time thermal monitoring with automatic thread reduction under pressure and request rejection at critical temperatures. Memory-aware model loading with conservative budgeting. Configurable request queues and per-request timeouts.

Built for Developers

- Live API docs with copy-paste curl examples

- Structured logging (debug, info, warning, error)

- One-tap copy for server addresses and API keys

What's Inside

Dashboard with one-tap server control, model manager with download progress, complete settings hub (server, inference, security, API keys, developer tools), and guided onboarding for first-time setup.
