modelgate-core

Reference implementation of MGS (Model Gate Standard) — pure-Python, zero infrastructure dependencies.

pip install modelgate-mgs

No FastAPI, no database, no message queue — this package is meant to be usable from a plain Python script, a notebook, or a CI job with nothing but pip install modelgate-mgs.

Usage

from modelgate import audit

report = audit("./my_dataset.zip")
print(report.overall_verdict)  # PASS / FAIL / NOT_EVALUATED
for r in report.requirements:
    print(r.id, r.verdict, r.metrics)

modelgate check ./my_dataset.zip --spec mgs-1.0 --json > report.json

Stable API surface (D5.1)

Only what's listed in modelgate.__all__ is covered by any stability guarantee:

• modelgate.audit(path, config=None) -> Report
• modelgate.read_dataset(path) -> Manifest — structure-only parsing, no Requirement checks run. Useful if you want a Manifest without paying for a full audit.
• modelgate.Report, modelgate.RequirementResult, modelgate.Manifest

Anything under modelgate._readers, modelgate._checkers, modelgate._rounding — the leading underscore is enforced, not just documented — may change shape between minor versions without notice. The modelgate check CLI's --json output shape (spec §4) is the other thing meant to be stable; parse that, not Python internals, if you're integrating from outside Python.
