Decisionmodelsio Eu: Decision Models s1-fast (EU)
Fast open typed-decision profile for text decisions; noul/choice/score answers with probabilities in milliseconds. An alias for the current Fast version (see model_version in every response and the S1-Model-Version header). s1-fast-1 is retired: requests for it are answered by s1-fast-2, and inputs s1-fast-2 cannot take are refused with HTTP 400.
