Which tier to use
What each costs against standard in our data, and the job it is for.
Dated snapshots
2 dated snapshots are listed at prices from the same price as standard to 60% cheaper than 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
gpt-4-1106-preview is a pre-release build, listed at 60% cheaper than 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 They can change behaviour or be withdrawn at short notice, so they suit trials rather than production.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-4 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.
