[cost\_intel] When should I use OpenAI's Batch API vs standard completions for cost reduction?

Use Batch API for any workload tolerant of 24-hour latency; it offers 50% discount on input/output tokens, making GPT-4o pricing comparable to GPT-4o-mini real-time rates with frontier quality.

Journey Context:
Teams pay premium real-time rates for backfill jobs, nightly report generation, or embedding updates that don't require immediate response. OpenAI's Batch API accepts jobs up to 24 hours with 50% pricing discount \(e.g., GPT-4o input $2.50/1M vs $5.00/1M\). This makes heavy GPT-4o workloads economically viable where mini models would compromise accuracy. The constraint is strict: once submitted, batches cannot be modified or cancelled easily, and results arrive asynchronously via webhook or polling. Error handling must accommodate partial failures within a batch \(individual requests can fail while others succeed\). Never use real-time GPT-4o for bulk historical processing; always queue to Batch API if the SLA permits overnight completion.
