[cost\_intel] When to use OpenAI Batch API vs realtime for high-volume production
Use Batch API when you can tolerate 24-hour latency and have >10k requests/day. Cost reduction is exactly 50% vs realtime. Break-even operational complexity at ~100k requests/month. Do NOT use for tasks requiring immediate error handling or user-facing latency <1s.
Journey Context:
Engineers default to realtime for reliability, but batch offers massive savings for asynchronous workloads like nightly reporting, bulk content generation, or embedding generation. The 50% discount is consistent across all models. The hidden cost is operational: you must handle the 24h SLA, implement polling for results, and manage partial failures without immediate feedback. At volumes below 100k/month, the infrastructure cost exceeds the savings. Quality is identical to realtime; the only difference is latency tolerance.
