const agent = new Agent({
  id: "my-agent",

  instructions: "You are a helpful assistant",
  model: "vivgrid/gpt-5.1-codex"
});

// Generate a response
const response = await agent.generate("Hello!");

// Stream a response
const stream = await agent.stream("Tell me a story");
for await (const chunk of stream) {
  console.log(chunk);
}
