[cost\_intel] When is OpenAI Batch API actually cheaper than synchronous calls?

Use Batch API only when you can tolerate 24h latency AND your volume exceeds 100k requests/day. For <10k requests/day, standard async with rate limit increases is cheaper due to no 50% discount threshold.

Journey Context:
The 50% discount on Batch API is seductive. But the hidden cost is latency—up to 24 hours. If your pipeline needs results in <1 hour, you're forced to use standard API. More importantly, the cost savings only materialize at volume: the overhead of managing batch files, S3/Azure storage, and error retry logic eats the 50% savings for small volumes. At 100k\+ requests/day, the operational overhead amortizes. Below that, you're paying complexity tax for marginal savings.
