LFM2.5-Audio-1.5B-OHF-Voice

Fine-tuned from LiquidAI/LFM2.5-Audio-1.5B on Paulescu/OHF-Voice-audio-20260504 to map spoken Home Assistant voice commands directly to function calls. Part of the Liquid Cookbook voice-assistant example.

Output format (no system prompt; the function set is baked into the weights):

HassStartTimer|$minutes=5|$name=oven
HassLightSet|$area=bedroom|$brightness=70
HassGetCurrentTime
