  let retryCount = 0;
  let retryDelay = 1000; // Start with 1 second delay
  
  while (retryCount < maxRetries) {
    try {
      const response = await fetch('https://api.openai.com/v1/chat/completions', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'Authorization': `Bearer ${API_KEY}`
        },
        body: JSON.stringify({
          model: 'gpt-3.5-turbo',
          messages: [{role: 'user', content: prompt}]
        })
      });
      
      if (response.status === 500) {
        throw new Error('Internal Server Error');
      }
      
      return await response.json();
      
    } catch (error) {
      console.log(`Attempt ${retryCount + 1} failed: ${error.message}`);
      
      if (retryCount === maxRetries - 1) {
        throw new Error(`Failed after ${maxRetries} attempts`);
      }
      
      // Add random jitter to prevent synchronized retries
      const jitter = Math.random() * 0.3 * retryDelay;
      const waitTime = retryDelay + jitter;
      
      console.log(`Waiting ${waitTime}ms before retry...`);
      await new Promise(resolve => setTimeout(resolve, waitTime));
      
      // Exponential backoff
      retryDelay *= 2;
      retryCount++;
    }
  }
}

2. Monitor API status headers: Pay attention to rate limiting headers in API responses
3. Implement circuit breakers: Temporarily disable API calls after multiple failures
4. Set longer timeouts: Increase request timeout thresholds for complex operations
