Model version name patterns
Stable
Points to a specific stable model. Stable models usually don't change. Most production apps should use a specific stable model.
For example: gemini-2.5-flash.
Preview
Points to a preview model which may be used for production. Preview model will typically have billing enabled, might come with more restrictive rate limits and will be deprecated with at least 2 weeks notice.
For example: gemini-2.5-flash-preview-09-2025.
Latest
Points to the latest release for a specific model variation. This can be a stable, preview or experimental release. This alias will get hot-swapped with every new release of a specific model variation.
For example: gemini-flash-latest.
Experimental
Points to an experimental model which will typically be not be suitable for production use and come with more restrictive rate limits. We release experimental models to gather feedback and get our latest updates into the hands of developers quickly.
Experimental models are not stable and availability of model endpoints is subject to change.
