[cost\_intel] Using synchronous API for batch-processable workloads and leaving 50% savings on the table
Route all non-latency-sensitive workloads through OpenAI Batch API or equivalent async endpoints. This includes nightly data processing, bulk classification, embedding generation, report generation, and any task with a >1 hour SLA. Expect 50% cost reduction with 24-hour turnaround.
Journey Context:
OpenAI's Batch API offers a flat 50% cost discount in exchange for up to 24-hour turnaround. The common failure mode is developers treating all API calls as latency-sensitive by default. Audit your pipeline: any step that doesn't feed a user-facing real-time response can likely use batch. Real examples: nightly content moderation sweeps, daily analytics report generation, bulk embedding updates for a vector store, weekly data enrichment pipelines. A team processing 10M classification requests/day via synchronous API at $0.15/M input tokens spends ~$1.5K/day; batch cuts this to $750/day — $273K/year in savings. The gotcha: batch requests have separate rate limits and queue depth, so validate turnaround during peak hours before committing SLAs.
