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 149.6M ModernBERT-base cross-encoder with a scalar head that picks an agent's next action or tool from labels and descriptions you supply. Each option is scored against the state and a softmax ranks the set; no text is generated. Experimental preview, not calibrated.

Questions
What is the difference between decision-flash and modernjev-decide?
decision-flash is from Telnyx and modernjev-decide from Maziyar Panahi. decision-flash is only available as a hosted API; modernjev-decide has open weights you can download and run. Both answer choice and route questions. Only decision-flash answers score, noul and classify. Only modernjev-decide answers rank. decision-flash is licensed proprietary; modernjev-decide, apache-2.0.
Which is more accurate, decision-flash or modernjev-decide?
Only modernjev-decide publishes an accuracy figure (73.4% on AgentToolDecisions-180K held-out test, next action type (1,158 decisions, 3 choices; the maker's split)); decision-flash does not, so there is no comparison to make without your own test.
Which is cheaper, decision-flash or modernjev-decide?
decision-flash: $0.035 / $0 per 1M. modernjev-decide: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run decision-flash or modernjev-decide locally?
modernjev-decide yes — systemone pull maziyar-panahi/modernjev-decide downloads its weights. The other is only served as a hosted API.
