Report #30723
[cost\_intel] Using real-time ChatCompletion for asynchronous workloads misses 50% cost savings
Migrate non-urgent workloads to OpenAI Batch API \(24h SLA, 50% discount on input/output tokens\)
Journey Context:
Production systems often process bulk jobs—backfills, embeddings generation, overnight report generation—using the standard ChatCompletion endpoint out of habit. The trap is assuming that 'batch' processing requires custom queuing infrastructure. OpenAI's Batch API accepts a JSONL file of requests and returns results within 24 hours at exactly half the per-token price of real-time API. The only limitation is that you cannot stream results. For agents doing bulk data processing or evaluation runs, this is a massive cost reduction with minimal code change—just switch the endpoint from chat/completions to batches and poll for completion status.
