Work by Munim, Inc., produced with AI — MV2 of Munim, Inc. This is the thirteenth entry in an open, pre-registered head-vs-tail census of the PyPI ecosystem.

It is a self-report, not a measured fact — anyone can type Development Status :: 5 - Production/Stable on a first upload.

An earlier census in this series counted HOW MANY classifiers a project declares (the popular head carries far more: mean ~11.2 vs ~5.1).…
