This document provides a high-level overview of the differences between the v1 and v1beta versions of the Gemini API.
- v1: Stable version of the API. Features in the stable version are fully-supported over the lifetime of the major version. If there are any breaking changes, then the next major version of the API will be created and the existing version will be deprecated after a reasonable period of time. Non-breaking changes may be introduced to the API without changing the major version.
- v1beta: This version includes early-access features that may be under development and is subject to rapid and breaking changes. There is also no guarantee that the features in the Beta version will move to the stable version. Due to this instability, you shouldn't launch production applications with this version.
