[cost\_intel] OpenAI Batch API is 50% cheaper but overlooked for offline jobs due to perceived complexity

Route all non-interactive workloads \(data labeling, embeddings generation, summarization backfill\) to the Batch API; use the standard API only for latency-sensitive user-facing requests.

Journey Context:
Batch API costs 50% less than standard API \(e.g., GPT-4o input at $2.50/1M vs $5.00/1M\). The trap is architectural: teams use the same HTTP client for everything, assuming 'batch' implies complex MapReduce infrastructure. In reality, it's a simple JSONL file upload with identical request format. The 24-hour latency is acceptable for most background tasks \(nightly reports, evaluation\). The alternative—using standard API with high rate limits—costs twice as much and risks throttling. Additionally, Batch API offers higher rate limits \(2x-5x capacity\). The quality is identical; there is no downside for offline tasks.
