Which tier to use

What each costs against standard in our data, and the job it is for.

Batch

The batch tier (gpt-4-turbo:batch) is 50% cheaper than standard. Batch requests are queued and answered asynchronously, typically within 24 hours, so it suits work nobody is waiting on: evaluations, back-fills, bulk classification and tagging. Anything a user is waiting on belongs on the standard tier.

Dated snapshots

One dated snapshot (gpt-4-turbo-2024-04-09) is listed at the same price as standard. A snapshot pins the model to one release, while the undated name moves to newer releases when the vendor updates it. Pin a snapshot in production when your prompts depend on exact output; use the undated name to pick up improvements automatically.

Direct or through a reseller

Through OpenRouter, gpt-4-turbo is the same price as buying direct. A reseller is worth it for one bill across vendors and automatic fallback; buy direct for the vendor's own batch, caching and rate-limit terms.
