Flows with these Nodes continue to work, and you can still edit and clone them as well as export them as a Package. However, you can’t create new ones in Cognigy.AI 4.96 or later. - On February 15, 2024, Google deprecated Gemini 1.0 Pro. The shutdown date for this model is April 9, 2025. Google recommends migrating to [Gemini 1.5 Pro and Gemini 1.5 Flash](https://cloud.google.com/vertex-ai/generative-ai/docs/deprecations/gemini-1.0-pro) before April 9, 2025. We strongly recommend carrying out this migration since Gemini 1.0 Pro support will be removed from future Cognigy.AI versions. - On April 29, 2025, we will discard `say` verbs with `empty text content` affecting the following Voice Gateway Nodes: -
