junnyofficial/nano_jevPython
junnyofficial/nano_jevPythonA pipeline that turns nvsh's Tool-Jev fine-tune process into a reusable factory for building jev-like models, with knobs and per-run decision tools, then fine-tunes its own model to make those decisions; the first model is not yet trained.
Jev Repos & SDKs#community#github#python
Community
agentculture/jev-factoryPython
agentculture/jev-factoryPythonA Python library shaped like the re module that finds, replaces, splits and extracts text by meaning: loose finders propose spans and Jev judges each one with a probability. Every match stays a verbatim slice of the input with its offsets, so it can be wrong but never invented.
Jev Repos & SDKs#community#github#python

nothans/ex-regexPython
nothans/ex-regexPythonAn unofficial Rust client for TypeSafe's System One API behind Jev: typed Noul, Choice, Score and Box questions, images, and both async and blocking clients. Its behaviour follows the official Python SDK, with the same environment variables, retry policy and error kinds.

phiat/typesafe-rust-sdkRust
phiat/typesafe-rust-sdkRustAn open-source, locally executed decision engine in the spirit of Jev (TypeSafe AI): state becomes features, and Noul, Choice and Score heads return typed, calibrated probabilities without generating text.
