What changed

d1-ultra is Liquid AI's largest decision model. It takes text and images plus one or more questions and returns probabilities for yes/no, choice or score answers in a single forward pass, with no token generation. It is built on a larger open-weight base model with Liquid customizations and trained for better-calibrated probabilities. Liquid AI reports significant gains over d1 across 112 evaluations, especially on knowledge tasks, and says it leads other decision models on the Artificial Analysis Decision Index by at least 8 points.

Access and availability

Available through the Liquid API (console.liquid.ai) decisions endpoint with model "d1-ultra", with demos in the d1 Playground. Liquid AI says Vercel and OpenRouter access is coming soon.

What you can build

Try it on a narrow classification or visual-inspection task with labeled examples, then check its decisions and probability calibration against human-reviewed outcomes.

Limitations

It cannot generate free text, only probabilities over defined answers. Parameter count and context length are not published, weights are not released, and all comparisons are provider-reported.
