PyMC Labs releases Marketing Foundational Model River trained on 200k simulated worlds
twiecki · x · 2026-10-31
PyMC Labs introduced Marketing Foundational Models (MFM) at ODSC AI West and released the white paper. The first model, River, is pre-trained once on 200,000 simulated marketing worlds and returns Bayesian MMM channel contributions with uncertainty in a single pass — removing the need to fit a separate model per dataset and promising faster, more accessible marketing measurement.
