About
Jev is a System One Model from TypeSafe AI designed for fast, structured decision-making inside software and automated workflows. Unlike conventional large language models that generate free-form text token by token, Jev accepts unstructured state and returns predefined type-safe values with calibrated probabilities and confidence scores. The model uses a parallel sampling architecture and a training approach called Reinforcement Learning for Calibrated Decisions, which is optimized for producing reliable probabilistic decisions rather than conversational responses. Jev is intended for tasks such as classification, routing, scoring, extraction, branching logic, verification, guardrails, and other AI-powered workflows where structured outputs can plug directly into application code. TypeSafe reports end-to-end response times ranging from about 70 to 500 milliseconds and says Jev can be substantially faster and more efficient than frontier language models on System One-style workloads.

About
Sage2 is a cloud-hosted AI model and API for developers building software agents and automated workflows. It accepts structured task instructions and returns decisions or extracted information in machine-readable formats, allowing applications to delegate steps such as classification, routing, evaluation, and data extraction to a model designed for tool-using agents. Developers can call Sage through its API, inspect model behavior in browser-based demos, and connect it to agent development environments including Cursor and Claude Code. The service offers API usage pricing with a free tier and paid monthly plans; usage charges and included credits vary by plan. Sage is intended for individual developers and software teams that want to add decision-making and extraction capabilities to applications without hosting the model themselves.
