# Domux: a compact open model for smart-home command understanding at the edge > Source: > Published: 2026-08-23 15:21:49+00:00 Voice and chat assistants for the home share a deceptively hard job: turning messy natural language into precise, structured commands. “Make it cozy in here” has to become a concrete intent plus the right slots — which device, which room, which value. **Domux** is an open model from iFlytek that focuses on exactly this problem: *command understanding* for smart-home assistants, framed as intent parsing and slot filling. `google/gemma-4-E2B-it` Building on the small Gemma-4-E2B base keeps Domux in a size class meant to run close to the device. 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.
