Liquid AI's first decision model, served only through the Liquid API. Returns Choice, Score and Noul answers with probability distributions and zero output tokens, on the /v1/systemone request shape used by TypeSafe's SDK.
A local, Jev-compatible decision model from Rizzo AI Academy. XHToken's Spark-X2.5-4B with a merged typed-decisions LoRA, run on llama.cpp; yes/no, choice and score questions share one prefill of the state and are read from the answer-letter logits. No text is generated.

Questions
What is the difference between d1 and rizzo-flow?
d1 is from Liquid AI and rizzo-flow from Rizzo AI Academy. d1 is only available as a hosted API; rizzo-flow has open weights you can download and run. Both answer choice, score, noul, classify and route questions. d1 is licensed proprietary; rizzo-flow, apache-2.0.
Which is more accurate, d1 or rizzo-flow?
Only rizzo-flow publishes an accuracy figure (64.8% on LocalLLaMA/typed-decisions test split (400 cases, 2,000 decisions), Q8_0); d1 does not, so there is no comparison to make without your own test.
Which is cheaper, d1 or rizzo-flow?
d1: Hosted, price not published. rizzo-flow: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run d1 or rizzo-flow locally?
rizzo-flow yes — systemone pull rizzo-ai-academy/rizzo-flow downloads its weights. The other is only served as a hosted API.
