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
gemini-2.5-flash-preview-09-2025 is a pre-release build, listed at the same price as standard. They can change behaviour or be withdrawn at short notice, so they suit trials rather than production.
