If you're choosing between open-weight models for a project, this framework helps you see past marketing and benchmark rankings to what's actually disclosed — weights, training data, architecture code — so you can judge fitness for your specific need (auditability vs. efficiency vs. customization).
An editorial argument that the label 'open' no longer describes one category of AI model but a bet on one of four distinct engineering goals: deep transparency, hardware efficiency, modular specialization, or raw frontier capability.
It breaks 'open' releases into six exposable layers (weights, license, architecture/inference code, training code, training data, and checkpoints/logs), showing why two models can both call themselves open while revealing completely different information, and why aggregate benchmarks collapse these incompatible goals into a single misleading number.

The better question is not “which open model is best?”
It is “which trade-off fits the task?”
We mapped the four camps and built a task-fit matrix for choosing between them.
