For home assistants, that direction is attractive: keeping command understanding on-device can reduce round-trips and keep more interaction local, instead of routing every utterance to a large hosted model.</p> <h2> Try it </h2> <p>The model card is on Hugging Face (access is gated — you may need to log in and request access):</p> <p>👉 <a href="https://huggingface.co/iFlytekOpenSource/Domux" rel="noopener noreferrer">https://huggingface.co/iFlytekOpenSource/Domux</a></p> <p>We're sharing open work like this because on-device, task-focused models are a practical piece of the foundation-model and serving story — not everything needs to be a giant cloud model.</p> opensource llm edgeai smarthome
