Hey @jaintarunAI can you please explain me what sort of functionality are you looking for using the LLM chain models ?

Hi @rexdivakar

Thank you for showing interest. The functionality for LLM Chain should take multiple input variables, uses the PromptEngine to format them into a prompt. It then passes that to the model.
