[cost\_intel] Using standard synchronous API calls for high-volume embedding generation
OpenAI's Batch API reduces embedding costs by 50% \(text-embedding-3-large\) with 24h turnaround; use it for backfill jobs >100k documents. Never use Batch API for latency-sensitive completion tasks requiring <5min response, but for RAG index builds, the cost reduction outweighs the delay.
Journey Context:
Teams process 1M documents via synchronous embedding calls at $0.13/1k tokens, burning budget. The Batch API offers 50% discount on embeddings specifically because they're stateless and parallelizable. The failure mode is queue depth: if you need embeddings in real-time for live RAG, batching fails. But for weekly index refreshes, it's 2x cost efficiency.
