Why certify here rather than with an AI model vendor?

A vendor certification certifies proficiency with that vendor's product, which makes it an adoption funnel with an exam attached. A lab that sells the model can't credibly certify your judgment over that same model's output.

This exam is vendor-neutral by construction, because you choose between pinned frontier models from different vendors inside the sitting itself.

The same logic holds against anything that scores how often you use AI rather than testing what you do with it. Frequency isn't judgment, and using it isn't directing it.
