[cost\_intel] Negative ROI from OpenAI Batch API due to latency constraints
Only use Batch API when 24-hour latency is acceptable AND daily volume exceeds 100k requests; for lower volumes or tighter SLAs, use standard async with exponential backoff to avoid working capital costs exceeding compute savings.
Journey Context:
Batch API offers 50% discount \($2.50/1M vs $5.00/1M for 4o\) but enforces 24-hour SLA. For a pipeline processing 10k requests/day, savings of ~$25/day are offset by customer churn or inventory carrying costs from 24h delays. The economic breakeven occurs at >100k requests/day where savings \($250\+/day\) exceed the cost of delayed value delivery. Additionally, during high load, batch queue depth can extend beyond 24h, creating unbounded latency risk not present in standard tier.
