Description

Jev is TypeSafe AI’s first public System One Model, a class of AI designed to make fast, structured decisions that software can consume directly. Instead of generating arbitrary strings like a traditional large language model, Jev produces predefined type-safe values accompanied by calibrated probabilities and confidence estimates. Its architecture generates outputs in parallel rather than autoregressively producing one token at a time, allowing the model to prioritize speed and computational efficiency. TypeSafe trains Jev using Reinforcement Learning for Calibrated Decisions, an approach intended to optimize for accurate uncertainty estimates and consistent structured outputs. The model can be embedded into conventional software as an intelligent decision layer for classification, scoring, routing, extraction, branching, and other tasks where hand-written rules would be too rigid. Jev can also be used to judge, verify, guardrail, or detect problematic behavior in outputs from other AI systems. TypeSafe reports typical end-to-end response times between 70 and 500 milliseconds and positions the model for applications where low latency is important. The company also emphasizes schema guarantees, meaning Jev’s outputs are constrained to the structures defined by the application rather than requiring developers to parse and validate unrestricted generated text. Jev is aimed at developers and organizations building automation, real-time software, large-scale data workflows, and production systems that require dependable structured AI decisions.

Description

Solar Decide is Upstage's decision-making framework that acts as a System One endpoint on Solar Mini 4. Rather than producing text, it processes a given state along with one or more specified questions to yield a selection, score, or a yes/no answer, complete with calibrated probabilities derived from the model itself. Each individual question is addressed in a single forward pass, which enhances the model's efficiency for tasks such as rapid classification, routing, policy validation, prioritization, and various other structured decision-making activities. The choice type allows users to select from a set of predefined alternatives, returning not only the chosen option but also the associated probabilities and confidence levels. In contrast, the score type measures an input against specific ranked criteria, providing a probability-weighted score, explanatory legend, probability distribution, and confidence metrics. Additionally, the noul type determines the likelihood that a yes-or-no statement is accurate. Users can submit multiple questions that reference the same state in a single request, with the state being provided as either plain text or any JSON value formatted for the prompt. This versatility makes Solar Decide a powerful tool for efficiently handling complex decision-making scenarios.
