// Don't do this

// Do this instead

// Bad — user waits 3-10 seconds staring at a spinner
const response = await client.chat.completions.create({

// Good — user sees text appearing in real-time
const stream = await client.chat.completions.create({

  messages,
  stream: true,
});

const response = await client.chat.completions.create({
