Report #38888
[cost\_intel] Running all inference through real-time API endpoints including non-latency-sensitive batch workloads
Route evaluation runs, bulk classification, dataset annotation, nightly ETL, and any workload tolerating 24-hour turnaround through OpenAI's Batch API for a flat 50% cost reduction with zero quality degradation.
Journey Context:
The Batch API provides identical model outputs at half price. The common mistake is treating it as a niche tool when it should be the DEFAULT for any non-interactive pipeline. For a bulk classification job processing 1M items on GPT-4o \($2.50/M input, $10/M output, ~1K input/100 output per item\): real-time cost = $3,500/month. Batch cost = $1,750/month. Savings: $1,750 for zero quality loss. The constraint is the 24-hour SLA and JSONL request formatting, but most batch pipelines already tolerate multi-hour runs. The signature of a batch-eligible workload: it runs on a schedule \(cron, Airflow\), doesn't serve a waiting user, and processes items independently. Google's Gemini Batch API offers similar economics. Anthropic does not yet have an equivalent batch endpoint, so for Claude workloads, prompt caching is the primary cost lever.
