Extended usage example


const llm = await agent.getLLM({
  runtimeContext: new RuntimeContext(),
  model: openai('gpt-4')
});

Options parameters

runtimeContext?:

RuntimeContext

= new RuntimeContext()

Runtime context for dependency injection and contextual information.

model?:

MastraLanguageModel | DynamicArgument<MastraLanguageModel>

Optional model override. If provided, this model will be used instead of the agent's configured model.

Returns

MastraLLMBase | Promise<MastraLLMBase>

The language model instance configured for the agent, either as a direct instance or a promise that resolves to the LLM.
