TypeSafe AI opened early access to Jev, its first System One Model for structured software decisions. The company said Jev accepts unstructured state and returns typed probabilistic decisions rather than generating strings. TypeSafe claims its architecture, parallel sampler and training approach make Jev faster and cheaper than comparable language models on its workflow evaluations. It also said the model supports a maximum choice cardinality of 255.
