JevMade field notes / Implementation and evaluation guide

Run and evaluate a local next-token Jev-style server

Simple Jev explains how a local Transformers and PyTorch server scores declared answers from next-token logits, constructs typed JSON, and evaluates behavior with JevBench tooling.

Before you dive in

What you’ll find in the original

  1. Send shared context and typed questions, then construct responses from answer scores rather than asking the model to generate JSON.
  2. Try the public endpoint within its 2,000-token context and two-requests-per-second limits before self-hosting.
  3. Use the included JevBench evaluation path and shared validation and prompt versions when comparing inference implementations.
Worth knowing

Local hosting requires Python, PyTorch, Transformers, and suitable model hardware. The public endpoint is unauthenticated but rate-limited; this independent implementation does not establish parity with Jev.
