Announcement · All Morph releases

reflex is Morph's decision model, served on its System One API (it launched there as d3-ultra). You send a state (text or any JSON value) and named questions, and it returns typed answers: the probability that a statement is true, a choice among options you define, or a position on your own rubric, each with a full probability distribution. It reads the state once and answers every question from that one read, and it generates no text, so answers cannot fall outside the options given. It speaks the same request and response format as TypeSafe's System One API, so code written for Jev can switch models by changing the model name. Use it where accuracy matters more than raw speed: routing and triage, guardrail checks, grading and extraction-style questions over long documents. On Opper it takes text and JSON states, and repeated input is billed at Morph's cached-input rate.
