Google AI Studio Announces Discontinuation of Select Gemini 1.5 Models, Encourages Migration to Gemini 2.0
[March 21, 2025] – Google AI Studio today announced the planned discontinuation of several Gemini 1.5 models, with the transition occurring in two phases over the next year. The move aims to streamline offerings and encourage developers to leverage the enhanced capabilities of the newer Gemini 2.0 family.
The models scheduled for discontinuation and their respective end-of-service dates are:
- May 27, 2025: Gemini 1.5 Pro 001, Gemini 1.5 Flash 001, and tuned versions of Gemini 1.5 Flash 001.
- September 24, 2025: Gemini 1.5 Pro 002, Gemini 1.5 Flash 002, and Gemini 1.5 Flash-8B 001.
Crucially, Google clarifies that the aliases “gemini-1.5-flash” and “gemini-1.5-pro,” which developers may be using in their code, currently point to the latest stable model, “-002.” Therefore, these aliases will remain functional until September 24, 2025.
“We are committed to providing our developers with the most advanced and efficient AI tools,” stated Google AI Studio. “This strategic move to discontinue select Gemini 1.5 models will allow us to focus our resources on the continued development and enhancement of the Gemini 2.0 family, which offers superior performance and features.”
To ensure a smooth transition, Google AI Studio is urging developers to migrate their projects to Gemini 2.0 Flash or Gemini 2.0 Flash-Lite. These newer models offer significant improvements in performance, efficiency, and cost-effectiveness. Google encourages developers to review the available model benchmarks, pricing details, and explore the Gemini 2.0 models at no initial cost.
Affected developers have been notified directly, with specific project IDs and project numbers provided for reference. Google AI Studio is committed to providing comprehensive support during this transition.
Key Actions for Developers:
- Migrate to Gemini 2.0 Flash or Gemini 2.0 Flash-Lite: To avoid service disruptions, developers should begin migrating their projects to the recommended Gemini 2.0 models.
- Review Gemini 2.0 Resources: Developers are encouraged to explore the available benchmarks, pricing, and free exploration options for Gemini 2.0 models.
- Address Affected Projects: Developers should review their projects, specifically those listed in the notification, and take the necessary migration steps.
