[cost\_intel] Message Batches async API pricing confusion causing double payment for synchronous needs

Use Message Batches only for workloads tolerant of 24-hour latency; avoid for real-time applications despite the 50% discount to prevent paying twice \(batch \+ standard fallback\)

Journey Context:
Anthropic's Message Batches API offers 50% discount but requires accepting 24-hour turnaround. Developers sometimes implement it as a 'cheap mode' with a fallback to standard API if results don't return quickly, effectively paying for both or complicating logic. The trap is treating batch pricing as a bulk discount for immediate use rather than a tradeoff for deferred processing. If your use case requires results in <1 hour, Message Batches will either fail your SLA or force you to maintain two code paths. Only use batches for offline processing, backfills, or non-urgent analysis where 24 hours is acceptable.
