Jev structured output language
10 items●1 sources●updated 1d ago●trend 1
Jev is a structured output language enabling agents to produce validated, type-safe outputs for testing and control across multiple platforms and domains. The system is being applied to iOS/Android/web testing, drug-discovery validation, drone swarm control, and competitive benchmarking against GPT-5.6 and Claude Haiku.
- Jev enables semantic end-to-end agent testing across iOS, Android, and web platforms
- Used as validation gate for drug-discovery agents and real-time control of 15 simulated drones
- Benchmarked against GPT-5.6 and Claude Haiku in game-playing tasks like Pong
- Mini-Jev provides local LLM implementation of typesafe's Jev language
- Powers S1Code, a decision-first Rust coding agent, and Probably, an LLM workflow language
