About d1

d1 is Liquid AI's first decision model. It reads unstructured input (text, images or both) plus one or more typed questions (Noul yes/no, Choice, Score) in a single forward pass and returns calibrated probabilities, generating no output tokens, via POST https://api.liquid.ai/decisions/v1/systemone (TypeSafe SDK-compatible). Liquid gives text decisions as 200–300 ms. Released 2026-09-22 (text). Image input was added 2026-10-05 on the Liquid API under the paid id d1: JPEG/PNG/WebP/GIF, up to 8 images and 10,000 32×32 patches per request, billed as input tokens at 1.5 tokens per patch.
