[cost\_intel] OpenAI Batch API cost-latency tradeoffs for high-volume processing
Migrate to Batch API only when processing >10,000 requests/day where 24-hour latency is acceptable. Batch provides 50% cost discount \($2.50 vs $5.00 per 1M tokens for GPT-4o\) but sacrifices real-time processing. Break-even volume: 10k requests amortizes the operational complexity of async result handling \(S3 buckets, webhook handlers, result polling\).
Journey Context:
Engineers assume batch processing is always cheaper for 'background jobs.' The hidden cost is infrastructure: managing async callbacks, result storage, and 24-hour SLA uncertainty. For 1,000 requests/day, the engineering overhead \(building S3 result buckets, webhook handlers\) exceeds the $50 saved. At 100k requests/day, the 50% savings \($5,000/day\) justifies dedicated infrastructure. The quality signature is identical—batch and synchronous GPT-4o share the same base model—so the decision is purely economic and architectural.
