[cost\_intel] Batch API reduces costs by 50% but latency spikes violate SLA for real-time user-facing features

Reserve Batch API for offline ETL and notification prep; never use for synchronous UI blocking paths. Implement async job polling with 24h timeout for batch workflows.

Journey Context:
OpenAI Batch API offers 50% discount but 24h turnaround. Common antipattern: wrapping batch in sync API call with 30s timeout. Results in 100% timeout rate and user-visible failures. Correct pattern: queue → batch → webhook callback. Cost savings materialize only in high-volume \(>10k requests/day\) offline pipelines. Attempting real-time use incurs 100% failure cost with zero savings.
