`Static`fromLLM

fromLLM(fields: Omit<LLMChainInput, "prompt">): LLMChain
Creates a new TaskCreationChain instance. It takes an object of type LLMChainInput as input, omitting the 'prompt' field. It uses the PromptTemplate class to create a new prompt based on the task creation template and the input variables. The new TaskCreationChain instance is then created with this prompt and the remaining fields from the input object.
Parameters
- fields: Omit<LLMChainInput, "prompt">
  An object of type LLMChainInput, omitting the 'prompt' field.
Returns LLMChain
A new instance of TaskCreationChain.
