Report #50371
[cost\_intel] When should I use OpenAI's Batch API \(50% off\) versus standard embedding calls for RAG ingestion?
Only use Batch API for embedding jobs >1 million tokens with 24-hour latency tolerance; for smaller jobs \(<500k tokens\) or near-real-time requirements, the 24-hour turnaround eliminates the 50% savings due to business velocity costs.
Journey Context:
The Batch API offers 50% discount but commits to 24hr SLA. For a daily RAG ingestion of 10M tokens, standard costs $1.00, batch costs $0.50. However, if your pipeline needs results in 1 hour for user-facing features, batch is unusable. Many over-engineer batch pipelines for 100k token jobs, saving $0.05 while adding 24hr latency.
