The Create by type buttons appear only when Prompt flow is opened in Microsoft Foundry (classic) within a hub-based project; they are unavailable in the new portal or a standard Foundry project.^1^
Create the Prompt flow
- In Microsoft Foundry, turn off the New Foundry toggle in the top banner.
- Open the required project.
- Check the breadcrumb under the project name:
- (Hub) means it is a hub-based project and supports Prompt flow.
- (Foundry) means it is a Foundry project and does not support Prompt flow.
- If it shows (Foundry), create or select a hub-based project instead. Prompt flow cannot be enabled inside that existing Foundry project.^1^
- Inside the hub-based project, select Prompt flow from the left navigation.
- If it is hidden, select … More at the bottom of the left pane and open or pin Prompt flow.
- Select + Create.
- Under Create by type, select Create on Standard flow, Chat flow, or Evaluation flow.
- Enter a folder name and select Create.
- When the editor opens, select Start compute session. A deployed model and compute session are required to run the flow.^2^
The classic Prompt flow documentation explicitly does not apply to Foundry projects.^3^
Alternative: Azure Machine Learning studio
If a hub-based Foundry project is unavailable, Prompt flow can also be created from an Azure Machine Learning workspace:
- Open the workspace in Azure Machine Learning studio.
- Select Prompt flow in the left navigation.
- On the Flows tab, select Create.
- Select Create on a flow-type tile, or Clone on a gallery sample.
- Open the flow and select Start compute session.^4^
Important lifecycle notice
Prompt flow is no longer recommended for new development and will be retired from Microsoft Foundry and Azure Machine Learning after April 20, 2027. For a new application, use Microsoft Agent Framework instead; plan migration for existing Prompt flow workloads.^3^
