UnverifiedDecisions API is a System 1 type model that does not follow the Next Token Prediction approach, but instead directly predicts the probabilities of various possible outcomes.79% similarUnverifiedv0.5.21 adds a Decisions API (/v1/decisions) that can turn large models into low-latency classifiers and scorers.75% similarVerifiedDecision-type models excel at structured tasks such as classification, routing, and judgment, rather than long-form text generation.73% similarUnverifiedThe output of a decision model is often a label or probability distribution over a finite action set, similar to a policy network in reinforcement learning, whereas generative models require autoregressive sampling over a large vocabulary.72% similarUnverifiedIn agent architectures, the Decisions API plays the role of the fast system in a fast-slow layered system, used to offload high-frequency, low-complexity decisions so that heavy reasoning models are only invoked at complex nodes71% similar
