Telnyx's hosted decision models, in beta on Telnyx Inference. One request carries shared state and up to 64 typed questions (choice, yes/no noul, ordered score) and returns a probability per option, with no generated text, on a TypeSafe-compatible /v1/systemone route.
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.

What is the difference between decision-flash and rizzo-flow?
decision-flash is from Telnyx and rizzo-flow from Rizzo AI Academy. decision-flash 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. decision-flash is licensed proprietary; rizzo-flow, apache-2.0.
Which is more accurate, decision-flash 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); decision-flash does not, so there is no comparison to make without your own test.
Which is cheaper, decision-flash or rizzo-flow?
decision-flash: $0.035 / $0 per 1M. rizzo-flow: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run decision-flash 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.
