const chat = new ChatOpenAI({
  modelName: "anthropic/claude-instant-v1",
  temperature: 0.8,
  streaming: true,
  openAIApiKey: $OPENROUTER_API_KEY,
}, {
  basePath: $OPENROUTER_BASE_URL + "/api/v1",
  baseOptions: {
    headers: {
      "HTTP-Referer": "https://yourapp.com/", // Optional, for including your app on openrouter.ai rankings.

      "HTTP-Referer": "https://yourapp.com/", // Optional, for including your app on openrouter.ai rankings.
      "X-Title": "Vercel Testing", // Optional. Shows in rankings on openrouter.ai.
    }
  }
})

const openrouter = new OpenAIApi(config)
