I see an id based ability suggesting `modelId`. but in current docs I cannot find any context to it. The other limit is that it suggests Swift Packages. but I'm not seeing any model management hints similar to Docker/Ollama/etc where:

- Application can ask for specific model, if available use it. if not, ask to download it (or try some fallback / alternative)

- User can manage models. So as a user I can clean unused models (and for non-techie have something similar to offloading apps when unused for some period of time).
