Automated README summary
Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
An LLM gateway and benchmark comparing TypeSafe Jev with Qwen 3.8 27B on Cerebras across seven synthetic workloads, recording latency, cost, and judgment quality for developers evaluating structured-output approaches.
How it uses Jev
Jev handles one application decision per request by batching native Choice/Noul questions, mapped to the same application output as Qwen's schema-constrained response. Results are validated before simulated actions; native probabilities remain in exports.
Primitives:choicenoul
Technique worth stealing
Compile application fields into compact numeric slots and batch native typed questions instead of one joint schema response.
Try it
npm ci; set CEREBRAS_API_KEY and JEV_KEY in .env; npm run build; npm run start:demos:live
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
