Report #30918

[cost\_intel] OpenAI Batch API 50% cost reduction requires 24-hour latency commitment

Route all non-interactive workloads \(evals, backfills, summarization jobs\) to Batch API; implement a job scheduler that aggregates requests and submits every 24 hours; never use Batch for user-facing synchronous requests.

Journey Context:
The Batch API offers half-price tokens but returns results within 24 hours. Production agents often default to the synchronous Chat Completions API for all tasks because the code path is uniform. This results in paying 2x for data processing, nightly report generation, or evaluation pipelines that have no latency requirement. The trap is architectural: the 'real-time' assumption is baked into the HTTP client wrapper, making Batch API adoption require refactoring rather than configuration.
