Common questions
How do I connect LM Mini to LM Studio?
Install LM Studio, start the Developer API server with Serve on Local Network, open LM Mini, enter your computer's LAN IP and port (e.g. http://192.168.1.100:1234), then pick a loaded model.
What is on-device AI in LM Mini?
On-device AI runs GGUF or MLX models directly on your phone or Mac so chat works offline without a PC server. The welcome flow and Get Started sheet suggest Faster / Balanced / Best picks for your RAM.
How does remote access work?
On Mac, LM Mini Home Share with phone pairs via QR with an encryption key only you control. Connect for Mac is deprecated through the end of 2026. Windows and Linux use LM Mini Connect.
How do I keep chats in sync between phone and Mac?
Pair the phone with LM Mini Home, then enable Sync chats with Home under Settings → Remote Access (or accept Keep chats in sync? after pairing). Conversations and folders stay aligned so you can continue on either device.
What replaced Connect for Mac?
LM Mini Home. Connect for Mac keeps working through 31 December 2026. Windows and Linux Connect remain current.
What are Personas?
Personas are saved AI characters with name, avatar, system prompt, preferred model/provider, Kokoro voice, and optional memory and ComfyUI workflow. New installs include a Default persona and Mini.
Does LM Mini support ComfyUI LoRAs?
Yes. In Settings → Image Generation choose ComfyUI, set your server URL, pick or paste a workflow, and use %LORA% / %LORA_WEIGHT% placeholders when needed.
How do I lock LM Mini with a PIN?
Pro users can open Settings → Data → App Lock, set a 4- or 6-digit PIN, and choose how long the app can stay closed before it asks again. The PIN stays on this device and is never synced. If you forget it, you must reinstall the app.
What is JAN AI in LM Mini?
JAN AI is a free local provider. Start the JAN app, add it in Settings → Server (default http://LAN-IP:1337), and pick a model JAN has loaded. Do not use localhost on a phone.
