# Get started with Amazon Bedrock in SageMaker Unified Studio


Get started with Amazon Bedrock in SageMaker Unified Studio by experimenting with a model in a [playground](bedrock-playgrounds.md).

The Amazon Bedrock in SageMaker Unified Studio playgrounds that lets you easily experiment with Amazon Bedrock models. The [chat](bedrock-explore-chat-playground.md) playground lets you chat with a model by providing text and image prompts to the model (not all models support images). The [image and video](explore-image-playground.md) playground lets you generate images and videos with a suitable model. With both playgrounds you can experiment by making configuration changes. For example, you can influence the response from a model by changing [inference](explore-prompts.md#inference-parameters) parameters.

After trying the chat and image playgrounds, you can try creating a chat agent app or flows app. A chat agent app allows users to chat with an Amazon Bedrock model through a conversational interface, typically by sending prompts (text or image) and receiving responses. To create a chat agent app, see [Build a chat agent app with Amazon Bedrock](create-chat-app.md).

You can also create a [flows app](create-flows-app.md) that lets you visually design the flow of an app.

## Chat with a model in the chat playground


In these instructions, you use the Amazon Bedrock in SageMaker Unified Studio chat playground to chat with an Amazon Bedrock in SageMaker Unified Studio model. You chat by sending a prompt to the model and answering the response that the model generates. For more information, see [Experiment with the Amazon Bedrock playgrounds](bedrock-playgrounds.md).

If you don't have access to a model, contact your administrator.

**To chat with a model**

1. Navigate to the Amazon SageMaker Unified Studio landing page by using the URL from your administrator.

1. Access Amazon SageMaker Unified Studio using your IAM or single sign-on (SSO) credentials. For more information, see [Access Amazon SageMaker Unified Studio](getting-started-access-the-portal.md).

1. At the top of the page, choose the **Discover**.

1. In the **Generative AI** section, choose **Chat playground** to open the chat playground.  
![\[Open Amazon Bedrock in SageMaker Unified Studio chat playground.\]](http://docs.aws.amazon.com/sagemaker-unified-studio/latest/userguide/images/bedrock/bedrock-ide-discover.png)

1. In **Type** select **Model** and then select a model to use in **Model**. For full information about the model, choose **View full model details** in the information panel. For more information, see [Find serverless models with the Amazon Bedrock model catalog](model-catalog.md). If you don't have access to an appropriate model, contact your administrator. Different models might not support all features.

1. In the **Enter prompt** text box, enter **What is Avebury stone circle?**.

1. (Optional) If the model you chose is a reasoning model, you can choose **Reason** to have the model include its reasoning in the reponse. For more information, see [Enhance model responses with model reasoning](https://docs.aws.amazon.com/bedrock/latest/userguide/inference-reasoning.html) in the *Amazon Bedrock user guide*.

1. Press Enter on your keyboard, or choose the run button, to send the prompt to the model. Amazon Bedrock in SageMaker Unified Studio shows the response from the model in the playground.  
![\[Run prompt in Amazon Bedrock in SageMaker Unified Studio chat playground.\]](http://docs.aws.amazon.com/sagemaker-unified-studio/latest/userguide/images/bedrock/bedrock-ide-chat-playground-run-prompt.png)

1. Continue the chat by entering the prompt **Is there a museum there?** and pressing Enter. 

   The response shows how the model uses the previous prompt as context for generating its next response.

1. Choose **Reset** to start a new chat with the model.

1. Influence the model response by doing the following:

   1. Enter and run a prompt. Note the response from the model.

   1. Choose the configurations menu to open the **Configurations** pane.  
![\[Inference parameters in Amazon Bedrock in SageMaker Unified Studio chat playground.\]](http://docs.aws.amazon.com/sagemaker-unified-studio/latest/userguide/images/bedrock/bedrock-ide-chat-playground-inference.png)

   1. Influence the model response by making [inference parameters](explore-prompts.md#inference-parameters) changes.

   1. (Optional) In **System instructions**, enter any overarching system instructions that you want the model to apply for future interactions.

   1. Run the prompt again and compare the response with the previous response. 

1. Choose **Reset** to start a new chat with the model.

1. Try sending an image to a model by doing the following:

   1. For **Model**, choose a model that supports [images](https://docs.aws.amazon.com/bedrock/latest/userguide/models-supported.html).

   1. Choose the attachment button at the left of the **Enter prompt** text box.   
![\[Run prompt in Amazon Bedrock in SageMaker Unified Studio chat playground.\]](http://docs.aws.amazon.com/sagemaker-unified-studio/latest/userguide/images/bedrock/bedrock-ide-chat-playground-run-prompt-attach.png)

   1. In the open file dialog box, choose an image from your local computer.

   1. In the text box, next to the image that you uploaded, enter **What's in this image?**. 

   1. Press Enter on your keyboard enter to send the prompt to the model. The response from the models describes the model or image.

1. (Optional) Try using another model and different prompts. Different models have different recommendations for creating, or engineering, prompts. For more information, see [Prompt engineering guides](explore-prompts.md#prompt-guides).

1. (Optional) Compare the output from multiple models, or [shared apps](bedrock-explore-chat-playground-app.md).

   1. In the playground, turn on **Compare mode**.

   1. In both panes, select the model that you want to compare. If you want to use a shared app, select **App** in **Type** and then select the app in **App**.

   1. Enter a prompt in the text box and run the prompt. The output from each model is shown. You can choose the copy icon to copy the prompt or model response to the clipboard.

   1. (Optional) Choose **View configs** to make configuration changes, such as [inference parameters](explore-prompts.md#inference-parameters). Choose **View chats** to return to the chat page.

   1. (Optional) Choose **Add chat window** to add a third window. You can compare up to 3 models or apps.

   1. Turn off **Compare mode** to stop comparing models.
