# Gemini Enterprise Agent Platform: gemini-2.5-flash retirement

## What breaks

Google lists gemini-2.5-flash with a retirement date in the model tables of its model versions page for Gemini Enterprise Agent Platform. The page does not describe what happens to requests to a retired model. It mentions only "errors caused by models reaching their retirement dates".

## What to do

Google links [Migrate to the latest Gemini models](https://docs.cloud.google.com/gemini-enterprise-agent-platform/models/migrate) as the guide for moving to a latest stable model. For cases where there is no time to follow the guide, the page gives a shorter path:

1. Update your application to point to the recommended upgrade. Where the table names a replacement for a model, it is in the "Replacement model ID" column.
2. Test all mission critical features to make sure everything works as expected.
3. Deploy the updates like you normally would.

## Replacement

gemini-3.8-flash or gemini-3.5-flash-lite
