What does model-agnostic mean in practice, not marketing?

The claim is made widely and delivered rarely. Supporting several providers means little if prompts were authored in one vendor's console, the index holds that vendor's embeddings, and conversation history lives under its retention policy. In that arrangement a switch means rebuilding the harness, which is where the accumulated work sits.

In Centralpoint prompts and skills are records in the organization's SQL environment, the vector index is built and held locally, and interaction logs are the organization's records. Model selection is a runtime setting across OpenAI, Anthropic, Google Gemini, Microsoft Copilot and embedded Llama, Qwen or ONNX. Adaptations for new providers ship every two weeks across all deployment modes.
