Open Source vs Proprietary Models: Deployment Trade-Offs in 2026

Model choice should be tied to deployment context, not benchmark headlines. Reliability and operational burden dominate long-term cost.

Hosted models reduce platform overhead and speed initial delivery, while self-managed options increase control but demand mature MLOps capability.

A mixed strategy often performs best: external inference for experimentation, targeted self-hosting for sensitive or cost-heavy workloads.
