The Batches API enables efficient processing of multiple requests in a single operation,

particularly useful for processing large datasets, batch evaluation workflows, and

cost-effective inference at scale.

The API is designed to allow use of openai client libraries for seamless integration.

This API provides the following extensions:

- idempotent batch creation

Note: This API is currently under active development and may undergo changes.
