The California Healthy Families Program (HFP) is the California implementation of the federal Children's Health Insurance Program (CHIP) that provides low cost insurance offering health, dental, and vision coverage to children who do not have insurance today and do not qualify for no-cost Medi-Cal.
Medi-Cal is cheaper than HFP in California.
Medi-Cal is no cost, but CHF is low-cost, therefore Medi Cal is cheaper. I think "cheaper" is the term that tripped up the AI.
