1//! Default model per provider.
2//!
3//! A provider configured with no model has to land somewhere. Picking the
4//! wrong entry is a billing decision, not a cosmetic one, so these track the
5//! defaults published by NousResearch/hermes-agent — the first entry of each
6//! provider's curated list, which is what its
7//! `get_default_model_for_provider()` returns.
8//!
9//! Only providers apollo can actually construct appear here. An unknown
10//! provider yields `None` and the caller keeps whatever the config already
11//! had, rather than being sent to a model that may not exist on it.
