Developer details production RAG pipeline challenges and cost optimizations

A developer detailed the challenges and solutions encountered when building a production-level system to score over 10,000 job listings daily using GPT-4. The initial setup suffered from rate limits and inefficient retry logic, leading to significant delays and increased costs. Key optimizations included a two-pass chunking strategy for more reliable structured data extraction, choosing the more cost-effective text-embedding-3-small model over the large version, and leveraging OpenAI's Batch API for a 63% cost reduction by accepting latency.
