jevper

What it is

jevper is an independent implementation of OpenAI's documented Decisions API schema and of the documented System One wire format. It is not affiliated with, endorsed by, or supported by OpenAI or TypeSafe AI — questions about those APIs belong in OpenAI's docs and TypeSafe's.

The homepage listed on the repository, zhulinchng.github.io, puts it like this: OpenAI Decisions API answers from any OpenAI-compatible model

Getting started

From the README:

pip install jevper

Where the decision sits

jevper calls the hosted decision API rather than running its own weights. That keeps the project small and means its behaviour moves whenever the vendor ships a new model version. It also means an API key and a network round trip sit in the path of every decision.

Models it references: Jev.
