SDK & Decision Frameworks Apache-2.0 E1 · source linked

JevPolicy is an open-source TypeScript decision runtime that turns probabilistic judgments from Jev, accessed through Vercel AI Gateway, into versioned, deterministic, replayable, observable application decisions.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

SDK & Decision Frameworks E1 · source linked

System One turns unstructured or structured state into fast probabilistic judgments. Instead of asking for free-form prose, these demos ask `Choice`, `Score`, and `Noul` questions and receive typed values with uncertainty that application code can reason about.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

CLI & Pipelines E2 · source reviewed

An early language experiment whose current implementation is a Jev request-batching spike.

JEV · Decision point

The script compares separate and batched answers, usage and latency; the full language engine remains a design goal.

Useful for studying batching, not a completed compiler or interpreter.
