Method GetService

Namespace

Assembly

GetService(Type, object?)

Resolves, in order: this when serviceKey is null && serviceType.IsInstanceOfType(this); ChatClientMetadata with ProviderName "onnxruntime-genai" and DefaultModelId = ModelId; ChatModelInfo; ChatClientStatistics; IChatModelHost; and, while this client holds the model, Model, Tokenizer and Config.

This method is the entire integration surface for three downstream consumers and is a contract, not an implementation detail: Semantic Kernel's GetModelId() is literally GetService<ChatClientMetadata>()?.DefaultModelId, Agent Framework's ChatClientAgent avoids double-wrapping by calling GetService<FunctionInvokingChatClient>(), and MEAI's own GetRequiredService<T>() goes through it. Returning the raw Model is also what lets a consumer build OnnxRuntimeGenAIChatClient, MultiModalProcessor or LoRA Adapters themselves without sub-project 4 wrapping any of it.

The three native objects are returned only while this client holds a lease - which, with the conversation cache on, is from the first turn until the cache is dropped. A model the host may dispose under the caller is never handed out.
