A model router on Jev

Overview & Result

Built a model router with Jev by @typesafeai. Jev decides what model fits your request best and the request is sent to that model.

How Jev fits in the loop

  1. Ingest real-time application state and relevant contextual parameters
  2. Format the decision problem as a bounded Choice or Noul schema
  3. Query Jev to receive a typed probability distribution in sub-50ms
  4. Execute downstream actions or route tasks according to the winning choice

How to reproduce

  1. Inspect the original showcase and source material at https://x.com/ephraimduncan/status/2100454070536351824
  2. Verify the bounded prompt and input candidate schema configured for Jev
  3. Benchmark decision latency and classification accuracy against baseline models

Why this build matters

Demonstrates a real-world, cost-effective implementation of Jev in a model routing & triage agent scenario, replacing expensive generative calls with fast typed decisions.

Reported performance

Reported by author

Latency: Sub-50ms deterministic decision window

Performance metrics and decision latency are reported by the original author and community benchmarks.

Limitations

  • Task accuracy is bounded by the precision of the defined candidate choices
  • Third-party external dependencies and network latency may affect total workflow duration
