[cost\_intel] Processing embedding generation for 10M\+ chunks via synchronous API calls without batching

Use OpenAI's Batch API for embedding requests; it offers 50% pricing discount \(e.g., text-embedding-3-large at $0.065/1M tokens instead of $0.13/1M\) for 24-hour asynchronous processing, cutting $1,300 worth of embedding costs to $650 at 10M scale

Journey Context:
High-volume RAG pipelines often trigger rate limits and run up bills with synchronous embedding calls. The Batch API is designed for exactly this: you submit a JSONL file with up to 50,000 requests, get results within 24 hours, and pay half price. The tradeoff is latency \(not suitable for real-time\) but for nightly index rebuilds or initial corpus ingestion, this is pure cost savings. Many developers don't know embeddings are eligible for batch pricing.
