# Modify an Amazon Bedrock prompt
Modify a prompt

You can modify the current draft of a prompt or modify previous versions of a prompt. To modify a prompt, you select the version of the prompt (or current working draft prompt) that you want to modify. You then work on a draft update of the prompt. You can change the configuration for different versions of a prompt. For example, different versions of a prompt can use different Amazon Bedrock in SageMaker Unified Studio models or use different inference parameters.

After testing the draft prompt, you can then save the draft as a new version of the prompt. If you want to use a new version of a prompt in a flow app, update the version of the prompt in the app configuration. For more information, see [Step 3: Add a prompt to your flow app](build-flow.md#build-flow-prompt).

Creating a new prompt version for an already shared prompt doesn't update the users that have access to the prompt version.

 For more information about the changes you can make, see [Create an Amazon Bedrock prompt](creating-a-prompt.md).
