Report #83099

[cost\_intel] When does OpenAI's batching API reduce costs vs standard API for embedding generation?

Use the Batch API for embedding jobs >100k documents; at 50% discount but 24h latency, it beats standard API on cost when throughput >$50/day, but loses on latency-critical RAG ingestion.

Journey Context:
OpenAI's Batch API offers 50% pricing discount in exchange for up to 24-hour latency. For embedding generation \(text-embedding-3-large\), this is pure cost optimization for backfill jobs, historical document ingestion, or offline feature stores. However, for real-time RAG pipelines where documents must be queryable immediately after upload, the latency cost \(user experience degradation\) outweighs the 50% savings. The break-even is typically when processing >100k pages per day or when the pipeline is naturally batch-oriented \(nightly ETL\).
