Report #71890
[cost\_intel] When does OpenAI Batch API reduce costs by 50% vs real-time for offline workloads?
Use OpenAI Batch API for any workload tolerant of 24-hour latency \(data preprocessing, embedding generation, bulk classification, backfills\). Batch pricing is 50% of real-time rates \(e.g., GPT-4o input $2.50 vs $5.00 per 1M tokens\). This allows using larger models \(GPT-4o vs GPT-3.5-turbo\) at equivalent cost with higher accuracy, or reducing costs by half at same quality.
Journey Context:
Teams run real-time pipelines overnight because 'batch is complicated,' but 24h SLA is acceptable for 90% of data engineering tasks. The savings flip the model selection logic: instead of downsizing to GPT-3.5-turbo to save money, you can upsize to GPT-4o in batch mode for the same price with better quality. Critical constraint: batch requires file-based input/output and handles only 50% of rate limit errors with automatic retry. Not suitable for <1 hour latency requirements.
