A model-agnostic platform separates its user workflow from the details of one provider. It may normalize model interfaces, route tasks, preserve common tools, compare outputs, and let users change models without rebuilding the complete application.
True portability is limited by differences in model behavior, tool protocols, context limits, pricing, safety rules, and access agreements. A neutral platform must continuously adapt to upstream changes and may become difficult to sustain when model providers favor their own vertically integrated products.

A model-agnostic platform is designed to work with several AI models instead of tying the whole product to one. Users can choose or switch models while keeping much of the same interface and workflow.
For example, a coding platform might offer models from several providers in one agent harness. Switching is not perfectly automatic because each model has different tools, limits, prices, and behavior, and providers can change the access they allow.
