Jev was tested in an AI customer feedback system using 1,040 GitHub issues, proving to be 98% cheaper and 84% faster than Claude Sonnet 4.6 while maintaining higher accuracy.
Jev classified 100 emails in 1.42 seconds, achieving 96% accuracy by routing uncertain cases to Kimi K3. The total inference cost was approximately $0.07.
Jev offers a new intelligent decision-making primitive that enhances model routing and classification tasks. It allows for quick and cost-effective decision-making, improving the efficiency of LLM calls in applications.
The Jev model was benchmarked against an ensemble of models for code reviews, achieving zero false positives, a review speed increase of ~50x, and a cost reduction of ~100x. It demonstrated a 75% bug recall rate, highlighting its efficiency compared to traditional multi-turn agent workflows.
The integration of Jev from @typesafe_ai replaced three steps in Prio, achieving 100% accuracy in model routing and significantly reducing action review time from 5 seconds to 0.25 seconds for clear cases.
Jev is a model that processes states and typed questions to return structured JSON with probability distributions. It outperforms previous setups in speed and cost, making it ideal for routing and decision-making tasks.
