Every model runs on your roadbed.

Any model on an open-weight base. Closed fine-tuning APIs retire models on their schedule, not yours.

Insurance. A claims-triage model on a closed API gets a retirement date. Last time this took two engineers six weeks, and the risk team had nothing to sign.

Banking. A KYC document model moves to a newer base and ships on overall accuracy. Portuguese ID cards drop 9 points, and nobody notices for a quarter.

Healthcare. A hospital group's clinical coding model cannot leave the network. So it stays on a 2024 base while open-weight models pass it every quarter.
