Jev structured output agent architecture
7 items●2 sources●updated 47d ago●trend 0
Jev is an open-source system-one agent architecture that uses structured output and typed decisions as core primitives, enabling faster, more reliable agent behavior without requiring specialized models. Created by TypeSafe AI (CEO Diogo Almeida), it works with any LLM and replaces traditional LLM judges with deterministic typed decision outputs.
- Open-source system-one agent architecture using structured output as core primitive
- Works with any LLM, not limited to specific models
- Replaces LLM judges with typed Jev decisions for deterministic outputs
- TypeSafe AI CEO Diogo Almeida leads the project
- Enables production-ready agents focused on decision-making, not general reasoning
