FAQ

Questions & answers

What models can I run?

Any GGUF-format model. The built-in store has popular models like Qwen, Llama, Mistral, DeepSeek, Gemma, and Phi — optimised for different RAM sizes. You can also import any GGUF model from Hugging Face.

Does it need an internet connection?

Only to download models from the store. Once downloaded, everything runs 100% offline on your Mac. No data ever leaves your machine.

What Mac do I need?

Any Mac with Apple Silicon (M1, M2, M3, M4) and at least 8 GB of RAM. More RAM = larger models. Even the base M1 MacBook Air can run smaller models comfortably.

What is the API Server feature?

It turns your local model into an OpenAI-compatible API endpoint. Tools like Open WebUI, Continue.dev (VS Code), LM Studio, or any OpenAI client library can connect to it — all running locally.

What is the IoT feature?

IoT tools (Pro plan) let you write sketches, use the serial monitor, and flash code to microcontrollers (e.g. Arduino-compatible boards) from inside nadster.ai. Connect a board via USB, edit code, and upload — no separate IDE needed.

How does pricing work?

We offer monthly subscriptions (Basic £3/mo, Pro £5/mo) with full support and free upgrades, or a one-time Lifetime purchase (£45) with 3 months support and free minor updates. Cancel monthly plans anytime. Enterprise: contact us for volume licensing.

Can I get a refund?

If nadster.ai doesn’t work on your Mac, contact us and we’ll refund you — no questions asked.
