[cost\_intel] Using standard chat completions for high-volume, latency-tolerant batch processing, paying 2x the necessary cost

Route all async, non-urgent workloads \(>1 hour latency tolerance\) to OpenAI's Batch API for 50% cost reduction with identical model quality and higher rate limits

Journey Context:
Many pipelines use standard API calls with retries and rate limit handling for bulk jobs like embedding historical documents or classifying backlogs. The Batch API is designed exactly for this: you submit a JSONL file, get results within 24 hours \(usually much faster\), pay half price, and get 10x higher rate limits. The mistake is treating 'batch' as just an implementation detail rather than a distinct API product with economic advantages. This is zero quality loss, pure cost optimization. Attempting to force real-time latency on batch workloads means paying the synchronous premium unnecessarily.
