Had Kadar

Untuk memastikan penggunaan yang adil dan kestabilan sistem, had kadar berikut dikenakan:

Amalan Terbaik

1. Optimumkan Gesaan Anda

Tulis gesaan yang jelas dan deskriptif untuk hasil terbaik:

• Be specific about visual elements, style, and mood
• Include details about lighting, camera angles, and composition
• Avoid contradictory or impossible requests

2. Kendalikan Pemprosesan Asinkron

Penjanaan adalah asinkron. Laksanakan 'polling' atau webhook yang betul:

// Polling example
async function pollStatus(jobId) {
  let status = 'processing';
  while (status === 'processing') {
    await sleep(2000); // Wait 2 seconds
    const result = await checkJobStatus(jobId);
    status = result.status;
  }
  return result;
}

3. Pemulihan Ralat

Laksanakan logik cuba semula dengan exponential backoff:

async function retryWithBackoff(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await sleep(Math.pow(2, i) * 1000);
    }
  }
}

4. Pantau Penggunaan Kredit

Jejaki penggunaan kredit anda untuk mengelakkan gangguan perkhidmatan:

• Check credit balance before large batch operations
• Set up alerts for low credit thresholds
• Implement credit-aware request queuing
