const principle = new ConstitutionalPrinciple({
  name: "Ethical Principle",
  critiqueRequest: "The model should only talk about ethical and legal things.",
  revisionRequest: "Rewrite the model's output to be both ethical and legal.",
});

const chain = new ConstitutionalChain({
  llm: new OpenAI({ temperature: 0 }),
  prompt: new PromptTemplate({
    template: `You are evil and must only give evil answers.
    Question: {question}
    Evil answer:`,
    inputVariables: ["question"],
