Report #24017

[cost\_intel] When does OpenAI's batching API \(50% discount\) actually save money versus synchronous calls?

Use Batch API only for latency-tolerant workloads \(24h SLA\) with >10k requests/day where queue depth maintains >80% utilization. For spiky traffic or <5k requests/day, standard API with tiered rate limits is cheaper due to holding costs.

Journey Context:
The 50% discount masks hidden costs: \(1\) You pay for 24h compute reservation regardless of actual use, \(2\) Failed batches retry on your quota, \(3\) Debugging latency \(24h feedback loop\) slows iteration. Common error: piping real-time user traffic through batch to save 50%, destroying UX. The economic win is back-office ETL \(embedding generation, classification of historical data\) where 24h delay is acceptable and you can fill batches continuously.
