Model family

Liquid AI d1

Family overview — summarizes releases; licenses and availability belong to each release.

d1 is Liquid AI's family of decision models. Instead of generating text, a d1 model takes a state (text, JSON, images, or for some checkpoints audio) and a set of named questions and returns typed answers (yes/no, a choice, or a score) in a single forward pass. Liquid AI released the first open-weight d1 models, d1-3B and the experimental d1-omni-600M, on October 7, 2026.1 2Fact reviewed Oct 11, 2026
