invoke

invoke(messages: BaseMessage[], runConfig: RunnableConfig): Promise<string>
Invoke LLM with a message and runnable config. For streaming use #stream method, streaming is preferred if model API supports it. Please note that this when tools are involved, this method will anyway do multiple LLM calls within LangChain dependency.
Parameters
- messages: BaseMessage[]
- runConfig: RunnableConfig
Returns Promise<string>

stream

stream(
messages: BaseMessage[],
runConfig: RunnableConfig,
): Promise<IterableReadableStream<string>>
Induce LLM to stream AI messages with a user message and runnable config. When stream is not appropriate use invoke.
Parameters
- messages: BaseMessage[]
- runConfig: RunnableConfig
Returns Promise<IterableReadableStream<string>>
