[cost\_intel] OpenAI Batch API latency cost trap for sub-100k daily request volumes

Avoid Batch API for workflows needing <24h turnaround or <100k requests/day; the 50% price discount is negated by idle compute costs and WIP inventory holding costs in production pipelines, making synchronous rate-limited calls cheaper for moderate volume.

Journey Context:
Batch API offers 50% cost reduction but with 24-hour SLA. The trap: production systems have 'freshness' requirements. If you're processing user data, holding it in a 'waiting for batch' queue for 24 hours incurs 'work in process' holding costs, database locks, and user experience degradation. Additionally, if your volume is sporadic \(e.g., 10k requests/day\), you pay the latency tax for marginal savings. The economic break-even is roughly 100k\+ requests/day where the 50% savings outweigh the pipeline complexity. For lower volumes, synchronous with exponential backoff is cheaper total cost of ownership.
