Easier Access with -latest Aliases
To simplify adoption, Google has introduced -latest aliases for each model family:
gemini-flash-latest
gemini-flash-lite-latest
These aliases always point to the newest preview versions, letting developers experiment with new features without constantly updating model strings. A 2-week notice will be provided before updates or deprecations.
For production stability, developers should continue using:
gemini-2.5-flash
gemini-2.5-flash-lite
