Struct ModelRegistry 

pub struct ModelRegistry { /* private fields */ }

A registry of supported models and their aliases, used to resolve user-facing model names to concrete provider-specific model entries.

The default registry is populated with all built-in models across supported providers (DeepSeek, NVIDIA NIM, OpenAI-compatible, and others).

Implementations

impl ModelRegistry

pub fn new(models: Vec<ModelInfo>) -> Self

Creates a new registry from a list of ModelInfo entries.

Builds an internal alias map for fast lookup by model id or alias. If multiple models share the same id or alias, the first one registered takes priority.

pub fn list(&self) -> Vec<ModelInfo>

Returns a clone of all models in the registry.

pub fn resolve( &self, requested: Option<&str>, provider_hint: Option<ProviderKind>, ) -> ModelResolution

Resolves a user-requested model name to a concrete ModelInfo.

Resolution follows this priority order:

1. If the provider is Ollama, the requested name is used as-is (to support arbitrary local model tags like qwen2.5-coder:7b).
2. If a provider_hint is given, search for a model matching that provider whose id or alias matches the request (case-insensitive).
3. Look up the alias map for a case-insensitive match.
4. Fall back to the first model belonging to the hinted provider (or DeepSeek if no hint was given).
5. As a last resort, fall back to the first model in the registry.
