Open Models Research

Compare open-weight models without treating every checkpoint as a separate product.

This view is generated from iilib's shared model graph. It focuses on representative, source-backed models and separates downloadable weights, licensing, commercial-use terms, architecture, self-hostability and research transparency.

“Open-weight” does not automatically mean “open source.” Custom community and vendor licenses remain visible instead of being collapsed into a single open/closed label.

Weights are only one part of the picture

4 models explicitly expose source code or recipes; 2 expose public training data; 2 expose training checkpoints. Missing transparency fields are not inferred from marketing language.

Method

Family, developer and hosted API availability are derived from verified graph relationships. Use-case labels are editorial research taxonomy, not benchmark rankings.
