[cost\_intel] Paying full price and fighting rate limits on batch processing and evaluation pipelines

Route any workload that tolerates up to 24-hour latency through the Batch API \(OpenAI\) or Message Batches API \(Anthropic\). Both offer exactly 50% cost reduction with separate, much higher rate limits.

Journey Context:
Many pipelines run evaluations, bulk classifications, or data enrichment through the standard chat completions endpoint, paying full price and competing with production traffic for rate limit quota. The batch APIs accept the same request format, process asynchronously within 24 hours, and charge half. A 10K-example evaluation run costing $50 at standard pricing costs $25 via batch. The only tradeoff is latency. For CI/CD eval runs, nightly data processing, offline enrichment, or dataset annotation, this is pure savings. People avoid it assuming complex setup, but it is a straightforward file-upload-and-poll interface on both providers.
