[cost\_intel] What is the cost and latency tradeoff of OpenAI's Batch API vs synchronous calls for high-volume offline processing?

Use OpenAI's Batch API for any offline workload \(e.g., nightly embedding generation, content moderation\) that can tolerate 24-hour latency; it offers 50% cost reduction and 2x higher rate limits compared to standard API calls.

Journey Context:
Standard API: pay full price, get response in seconds. Batch API: pay 50% of standard price, get results within 24 hours \(typically 1-4 hours\). For a nightly job processing 1M embeddings: standard cost ~$20, batch cost ~$10. The hidden value is rate limit avoidance; batch jobs use separate, much higher quotas \(10x standard TPM\). Common mistake: assuming batch is only for 'next day' jobs. Many teams have 'near real-time' tasks with a 4-hour SLA where batch is viable and 50% cheaper is left on the table. Error handling differs: batch failures return after hours, not seconds, so you need robust checkpointing and retry logic.
