You'll notice
The 'fable' model family's picker entry lost its description text, now shows just a name
What
The code that builds a model picker entry for the "fable" model family used to return a rich object including a label and description text ("most capable for your hardest and longest-running tasks"). It now just returns the model's display name, or nothing if there isn't one.
Why
This means the picker no longer shows explanatory description text for the fable family in this particular code path, just its plain name.
