Knowledge cutoff

The date past which a model has no parametric knowledge. Libraries, APIs, and events from after the cutoff are fabrication traps unless their docs are loaded as contextual knowledge. Each model release ships with its own cutoff.

Usage:

"It keeps writing the v3 SDK syntax — we're on v5."

"v5 shipped after the knowledge cutoff. Load the v5 changelog as contextual knowledge, otherwise it'll keep fabricating from the older parametric version."
