About Jev
Jev is a System One AI model from TypeSafe AI designed for high-speed, low-cost decision-making and structured outputs. It operates as a composable intelligence system optimized for tasks requiring rapid inference and precise actions. The model is positioned as a cost-effective alternative to larger frontier models, with reported speed improvements of 20-200x and cost reductions of 40-400x, including free output tokens. Jev is typically used in agentic workflows where an LLM handles writing, Jev makes decisions, and code executes actions. It supports applications such as browser automation, real-time gaming, content analysis, lead scoring, and triage systems. The model is accessed through a workflow that splits tasks into decision, writing, and execution phases, enabling efficient and scalable AI-driven processes.
