Note
Currently, there are two UIs that support Workflows: Yandex Cloud and Yandex AI Studio. In this case, the following applies:
- Workflows created in the Yandex Cloud UI are automatically available in the AI Studio UI.
- Workflows created in the AI Studio UI are not available in the Yandex Cloud UI.
Starting September 3, 2026, Workflows will no longer be supported in the Yandex Cloud UI. To create and manage workflows, use the AI Studio UI.
