[cost\_intel] Batch API used for latency-sensitive workflows

Reserve Batch API for >100k requests/day with >24h SLA; use synchronous API for sub-5-minute latency requirements despite 2x cost premium.

Journey Context:
OpenAI's Batch API offers 50% pricing discount \($2.50 vs $5.00 per 1M tokens for GPT-4o-mini\) but enforces 24-hour maximum turnaround with no completion guarantees. Teams often route all traffic through Batch to save money, breaking real-time user flows. The economic break-even requires volume: at 100k requests/day, the 50% savings \($500/day for mini\) outweighs the complexity of maintaining dual pipelines and handling 24-hour latency windows. For lower volumes, the engineering cost of async job management exceeds the API savings. Critical insight: Batch API counts input tokens at write time, so you pay for cached tokens even if the job fails or is cancelled, unlike synchronous API where you only pay for completed requests.
