Report #78424
[cost\_intel] At what volume does OpenAI Batch API become cheaper than real-time, and what are the hidden latency costs?
Switch to Batch API when processing >100k requests/day; the 50% discount outweighs the 24-hour latency only for non-real-time workflows like embeddings or overnight data processing.
Journey Context:
Teams often assume batch is always better for cost. The trap: 24-hour turnaround means you need 2x the buffer capacity in your queues. For real-time use cases \(user-facing chat\), the latency kills the UX. For embeddings or classification of backlogged data, it's perfect. The crossover point is ~100k requests/day where the 50% savings \($0.001 vs $0.002 for embeddings\) justifies the infrastructure to handle delayed responses.
