Liquid AI releases d1-3B and d1-omni-600M, open-weight decision models that produce answers in a single forward pass rather than generating tokens. d1-3B achieves 48.57 on the Decision Index, matching much larger models while running in 8ms on RTX 4090 and 50ms on Jetson Orin Nano. d1-omni-600M, an experimental multimodal checkpoint, handles text with images or audio.
