Model Portability Becomes Margin Discipline
Projection: Application companies will measure how quickly context, evaluations, and workflows can move between model providers without degrading outcomes. Portability is not the moat itself; it is a margin discipline that limits dependency and preserves negotiating leverage. Adoption becomes visible in provider-switch drills, dual-running evaluations, and disclosed migration cost.
Why this idea is here
What the evidence establishes.
The cited captures establish adoption, funding, and model-layer competition. They do not establish portability drills as a standard practice; the test is whether applications can switch providers while preserving outcomes at a measured migration cost.
