Model catalog
Every model, one request shape.
Frontier and open-weight models side by side. Pick by job, price, and capability, then send the ID in model. The ID you send is the model you get.

VIABLE aliases are stable names. VIABLE Lab manages the model behind each one, so your code keeps working as models improve.
