[cost\_intel] When is OpenAI's Batch API 50% discount worth the 24-hour latency tradeoff?
Use Batch API for any non-real-time workload exceeding 100k requests/day; the 50% discount \(GPT-4o at $1.25/MTok vs $2.50/MTok\) outweighs latency costs for embeddings, classification, and offline generation backfills.
Journey Context:
Standard GPT-4o costs $2.50/MTok; Batch API costs $1.25/MTok. For a 1M request backfill, standard costs $2500, batch costs $1250. The 24h SLA is acceptable for data pipeline backfills, model distillation, or nightly report generation. Common error: using batch for user-facing real-time features, breaking UX for marginal savings.
