[cost\_intel] Synchronous embedding pipeline throttling and 50% cost premium

Use OpenAI Batch API for embedding jobs >100k texts or async embedding with 500 req/s concurrency to unlock 50% pricing discount vs synchronous. Break-even at 10k items.

Journey Context:
Developers process embeddings sequentially, hitting TPM/RPM limits and paying standard rates. The OpenAI Batch API offers 50% discount for 24h turnaround on eligible models \(text-embedding-3-large\). For real-time needs, high-concurrency async \(e.g., 500 parallel requests with exponential backoff\) maximizes throughput without Batch API latency. The error is assuming RAG indexing requires synchronous processing; most use cases tolerate 24h delay for bulk indexing, making Batch API a 50% cost reduction with zero quality impact.
