11	* The server's preferences for model selection, requested of the client during sampling.
12	*
13	* Because LLMs can vary along multiple dimensions, choosing the "best" model is
14	* rarely straightforward. Different models excel in different areas—some are
15	* faster but less capable, others are more capable but more expensive, and so
16	* on. This interface allows servers to express their priorities across multiple
17	* dimensions to help clients make an appropriate selection for their use case.
18	*
19	* These preferences are always advisory. The client MAY ignore them. It is also
20	* up to the client to decide how to interpret these preferences and how to
21	* balance them against other considerations.
