Report #84102

[cost\_intel] When is OpenAI's Batch API worth the 24-hour latency tradeoff?

Use Batch API only for \(1\) >100 requests/job, \(2\) latency tolerance >24h, and \(3\) no inter-request dependencies. Cost savings are 50% on input/output tokens, but overhead dominates below 100 requests.

Journey Context:
OpenAI's Batch API offers 50% discounts on all tokens but processes with 24-hour SLA. The fixed overhead of job management makes it uneconomical for small batches: a 10-request batch saves 50% on tokens but the latency cost and queue overhead often exceed savings. At >100 requests, the 50% discount on heavy token loads \(e.g., embedding generation for 1M documents\) creates order-of-magnitude savings. The failure mode is teams batching critical real-time requests, violating the 24h SLA, or batching tiny payloads where the 50% discount doesn't offset the operational complexity.
