Which tier to use

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

Batch

The batch tier (gpt-4o-mini: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.

Audio, Search variants

The vendor also lists audio, search variants of gpt-4o-mini, listed at the same price as standard. They are the same model tuned or wired for one job, so pick one only when that is your job; otherwise standard is the reference price.

Dated snapshots

4 dated snapshots are 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.

Preview and beta

3 pre-release builds (preview, beta or experimental) are listed at the same price as standard. They can change behaviour or be withdrawn at short notice, so they suit trials rather than production.

Direct or through a reseller

Through OpenRouter, gpt-4o-mini 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.
