About

d1 is Liquid AI's decision model family for typed Noul/Choice/Score answers with calibrated probabilities via the Liquid Decisions API (POST /decisions/v1/systemone) — not a chat LLM family. First public model id d1:free is API-only (no public HF/GGUF weights in the Liquid model matrix). Peer of TypeSafe Jev as a decision model: own Liquid lab family; do not attach under system-one, jev, lfm-2, or lfm-2.5. Proprietary hosted.
