Description

This course provides a clear, beginner-friendly introduction toJev by TypeSafe AI, a System One model designed for structured AI decision-making inside software applications.
Traditional generative AI models are mainly designed to generate text, explanations, code, and conversations. Jev takes a different approach. Instead of producing long open-ended responses, it helps applications make focused decisions using structured outputs, probabilities, and confidence signals that software can use directly.
The course begins with the fundamentals ofTypeSafe AI, Jev, and System One models. You will understand why Jev was created, how it differs from traditional Large Language Models, and where decision-oriented AI can fit into modern applications.
You will then learn how to work withState and how to design clear and focused questions for Jev. The course explains Jev's three core decision primitives -Choice, Score, and Noul - and shows when each one should be used.
As you progress, you will explore how Jev represents uncertainty usingprobabilities and confidence, and how applications can use decision thresholds to control automation, routing, and review.
The course also introduces important Jev architecture and decision patterns, includingparallel questions, speculative fan-out, intent routing, confidence-based routing, and composite decision logic. You will see how Jev can work alongside normal application code while keeping business logic and final actions under software control.
You will also study Jev's current models, limitations, production considerations, and real-world use cases. This helps you understand not only where Jev performs well, but also when traditional code or a generative AI model may be a better choice.
The course includestwo hands-on lectures where you will get started with Jev, make your first calls, and integrate Jev into aPython application.
This course is suitable forPython developers, AI engineers, software developers, Generative AI learners, and anyone interested in understanding modern decision-oriented AI systems with Jev.
