[cost\_intel] Using real-time API for large-scale embedding generation jobs

Use OpenAI Batch API for embedding jobs >1M tokens; identical model quality \(text-embedding-3-large\) at 50% cost \($0.013 vs $0.026 per 1k tokens\) with 24-hour SLA

Journey Context:
Engineers processing millions of documents for RAG pipelines use the standard Embedding API synchronously, paying full price and managing rate limits. The Batch API offers exactly the same model with exactly the same quality but at half price in exchange for asynchronous processing \(24-hour turnaround\). For weekly or monthly index rebuilds where real-time is unnecessary, this is pure cost savings. 1 billion tokens of embeddings costs $13,000 via Batch vs $26,000 standard. No quality degradation, no model difference.
