Why does model choice need to be changeable rather than just correct?
Capability gaps between leading models narrow every release cycle, prices move, terms change and availability varies by jurisdiction. Any selection made now will be revisited — the question is whether revisiting it is a setting or a project.
Centralpoint selects the model at runtime and holds the index, prompts and skills in the organization's environment, so switching requires no re-indexing and no rule rewriting. That keeps the option open commercially as well as technically: a provider whose pricing can be walked away from negotiates differently, and multi-provider consumption still consolidates onto one invoice below published rates.
