Report #65977
[cost\_intel] OpenAI Batch API latency-cost tradeoff misunderstanding
Use Batch API for any workload tolerating 24h latency and >10k requests/day; it provides 50% discount on all models including GPT-4o and o1-preview with identical quality. Submit before 6pm PST for next-day turnaround.
Journey Context:
Engineers assume batch processing is only for data pipelines, missing that it applies to any non-realtime task \(email classification, document tagging, overnight report generation\). The error is paying full price for asynchronous workloads. The 50% discount applies to input and output tokens; for GPT-4o at scale, this reduces $5/15 per 1M to $2.50/$7.50. The only constraint is the 24-hour SLA, which is acceptable for any offline processing.
