Frequently Asked Questions

What is the Batch API?
Anthropic and OpenAI both offer a Batch API: submit jobs, get answers within 24h, pay 50% less. Great for evals, content generation, classification at scale.
When does it NOT work?
User-facing chat, real-time agents, anything with <1 hour SLA. Batch is async by definition.
Can I mix?
Yes — many production stacks send urgent queries via streaming and overnight workloads (eval, refresh) via batch. Best of both.
