AI Model Exit Strategy: Proven Guide to Avoid Costly Risk
Model portability is an engineering property, not a legal one. This guide sets out where AI lock-in actually forms across five layers — the API surface, the prompt estate, embeddings, fine-tunes and the evaluation record — and what a switch really costs at each level of preparation. It covers the abstraction patterns that pay for themselves, why an evaluation harness is the instrument that makes a switch defensible, which assets transfer between models and which do not, the contract terms that keep the door open, and a 90-day runbook you can run without pausing delivery.
