[cost\_intel] How to reduce OpenAI API costs by 50% without changing the model
Use OpenAI's Batch API for any workload tolerating 24-hour latency; it offers 50% discount on input/output tokens with identical model quality and 0% availability SLA impact
Journey Context:
Engineers often assume real-time is required for all pipelines. However, background tasks \(embedding backfills, nightly report generation, bulk content moderation\) can tolerate delay. The Batch API \(JSONL file upload\) processes at half price. Tradeoff: loss of streaming, 24h SLA, and requires file management. Critical: not suitable for user-facing latency-sensitive features. The 50% discount applies to all tokens including expensive reasoning models.
