Sommmelier

What it does

Sommmelier fits marketing mix models on cloud GPUs, diagnoses what is limiting them — convergence, overfitting, carryover windows — and re-runs with fixes rather than handing you a number and wishing you luck.

It runs Google Meridian on Modal, which puts a fit at roughly thirty cents. Shared agent skills let a coding agent act as the analyst layer on top.

Where it is up to

Early. The outputs are directional and worth arguing with; they are not budget decisions.
