  model: "openai/gpt-4o",
  messages: [
    {
      role: "user",

Structured Outputs

const response = await client.chat.completions.create({
  model: "openai/gpt-4o",
  messages: [{ role: "user", content: "Cuaca di Jakarta" }],
  response_format: {
    type: "json_schema",
    json_schema: {
      name: "weather",
      strict: true,
      schema: {
        type: "object",
        properties: {
          location: { type: "string" },
          temperature: { type: "number" },
        },
        required: ["location", "temperature"],
