Report #36299
[cost\_intel] OpenAI Batch API 50% discount negated by 24-hour latency blocking debugging iteration cycles
Restrict Batch API to production workloads with validated prompts; use standard API for development, testing, and prompt engineering even at higher per-token cost
Journey Context:
Batch API offers 50% cost reduction but processes jobs in 24 hours. During prompt development, engineers need sub-minute feedback loops to debug failures. Using Batch for development creates a 24-hour iteration cycle, destroying engineering velocity. The cost 'savings' are consumed by calendar time and blocked debugging. The correct economic model treats Batch API as a production optimization only, after prompts are frozen. The trap is treating Batch as 'cheaper API' rather than 'deferred batch processing,' leading to development paralysis.
