Why does AI quality degrade when processing large batches?

AI quality degrades with large batches due to context window limitations and rate limiting.

Root causes:

  • Context window overflow when processing too many items
  • Rate limiting causes retries with degraded quality
  • Token limits force truncation of context
  • Temperature drift over long sessions

Solutions:

  1. Keep batches small:

    • Batch size: 25 max (10 for personalization)
    • Add 2-second delay between batches
  2. Quality controls:

    • Include confidence score in output
    • Set minimum confidence threshold (0.
    • Retry low-confidence results with better model
  1. Output validation:

    • Minimum/maximum length checks
    • Must mention company name
    • Cannot contain generic phrases ("I hope this email finds you")
  2. Retry strategy:

    • Max 2 retries per item
    • Use different (better) model on retry
    • GPT-4 for critical failures

Pro tip: Test your prompt on 25 items first, validate outputs, then scale up. Don't jump straight to 400.
