We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Instructions
- Use the Message Batches API when work is not time-sensitive and you can wait up to 24 hours for completion. - Design each batch for high volume (up to 10,000 queries) and plan for asynchronous retrieval of results. - Use batching to reduce cost (50% discount on input and output tokens) and to increase throughput without consuming standard API rate limits. - Prefer batching for large-scale analysis/classification/translation/evaluation workloads where you would otherwise build complex queueing.
Examples
- "We need to classify 2 million support tickets into 20 labels over the weekend—use the Batches API design checklist." - "Translate a large set of product descriptions where same-day delivery is fine; estimate cost savings vs standard calls." - "Run an offline model evaluation suite with 8,000 prompts; plan the batch submission and result download flow."
