The valuable asset in a mature deployment is not the model but the body of work that makes it answer correctly for this organization: the prompts encoding how questions should be handled, the rules encoding what is never permitted, the domain knowledge that took subject experts months to articulate. Where that work is stored determines whether it is an asset or a dependency. Stored inside a vendor's product it is leverage held by the vendor; stored in the organization's own environment it is portable across any model and survives a change of supplier.
