[cost\_intel] Using synchronous real-time API calls for bulk processing with no latency requirement
Route non-urgent workloads \(nightly ETL, bulk classification, dataset annotation, batch summarization\) through batch APIs. Accept up to 24-hour turnaround for a 50% cost reduction with zero quality degradation.
Journey Context:
Both OpenAI and Anthropic offer batch APIs that queue requests and process them within 24 hours at exactly 50% discount. The output quality is identical — same model, same prompt, just deferred execution. For a pipeline processing 1M items/month at $3/1M input tokens on Sonnet, switching to batch saves ~$1,500/month or $18K/year with zero code changes beyond the API endpoint. Common mistake: building always-on real-time infrastructure for workloads whose consumers are asynchronous \(dashboards updated daily, databases populated overnight, ML training sets annotated weekly\). If the result is not shown to a user in real-time, it should go through the batch API.
