[cost\_intel] Batch API's 50% discount is only worthwhile when the 24-hour turnaround and late failure handling are acceptable

Use Batch API only for offline, idempotent work where results can wait up to 24 hours; keep synchronous calls for anything that feeds a user-facing state machine or requires fast retry loops.

Journey Context:
OpenAI Batch API cuts token cost by 50% and has its own, much higher rate-limit pool. The catch is a 24-hour completion window and failures that surface late in a separate error file. If your pipeline schedules downstream work assuming batch success, a single late failure cascades into re-runs, monitoring, and idempotency engineering that can erase the savings. Batch is a clear win for embeddings, summarization, and classification of stored datasets; it is usually wrong for interactive agents or freshness-sensitive tasks. The quality/cost tradeoff is not about model behavior—the same model runs—but about operational latency and error-budget timing.
