Anthropic's Message Batches API processes up to 10,000 Claude queries asynchronously at half the cost of standard API calls, ideal for large, non-real-time workloads.

Anthropic's Message Batches API allows developers to process high volumes of Claude queries (up to 10,000 per batch) asynchronously, offering a 50% cost reduction compared to synchronous API calls. This service is designed for tasks that do not require real-time responses, with a 24-hour service level agreement (SLA), though most batches complete much faster. It supports models like Claude 3.5 Sonnet, Claude 3 Opus, and Claude 3 Haiku, enabling cost-effective solutions for large-scale data analysis, content generation, classification, and extensive model evaluations. The API accepts requests directly via a JSON POST request, simplifying submission and integrating with existing workflows.
