Class CallbackManager

Example

const prompt = PromptTemplate.fromTemplate('What is the answer to {question}?');

// Example of using LLMChain with OpenAI and a simple prompt
const chain = new LLMChain({
llm: new ChatOpenAI({ temperature: 0.9 }),
prompt,
});

// Running the chain with a single question
const result = await chain.call({ question: 'What is the airspeed velocity of an unladen swallow?' });
console.log('The answer is:', result);
