title: "Wald-Q4B v1.2: an open-weight 4B decision model with calibrated option probabilities"
abstract: >-
  Wald-Q4B is an open-weight 4B decision model built on Qwen3.5-4B-Base. Given a
  state and typed questions (choice, yes/no, score), it returns a calibrated
  probability for every option through a Jev-compatible POST /v1/systemone API,
  in one pass or after an optional short thought. Weights and serving code are
  Apache-2.0. Independent project; not affiliated with TypeSafe AI.
