The Model Playground provides an interactive interface for testing and comparing foundation models before integrating them into your applications.

In the Model Playground, you can:

• Send prompts to different models and review their responses.
• Generate multimodal artifacts from supported models.
• Upload images from local storage.
• Adjust model parameters such as temperature and token limits.
• Compare outputs across models to evaluate quality and suitability.
• Explore which models best fit your use case.

You are prompted to confirm billing in the Confirm Standard Billing for Playground Usage window. After you confirm, usage is billed according to the pricing for the model playground.

To use the Model Playground, in the DigitalOcean Control Panel, click Serverless Inference under INFERENCE in the left menu. Then, select the Model Playground tab.

Test Models

To test a foundation model, on the Model Playground page, select a model from the dropdown list. The playground displays a capability-driven model card to suggest what you can try with the model, instead of pre-filling a single example prompt. Each model card summarizes capabilities such as intended use, parameters, and context length to help you shape your request.

You can send text prompts and multimodal requests to generate audio, images, or text-to-speech when the model supports it. Type your question or request in the Type your message text box. To learn the best practices for how to write questions for the model, see Best Practices for Prompt Writing.

You can also add images to your prompt. Click + next to the input field. To upload an image from your local storage, select Upload File.

After the model responds, review the length, style, and speed of the output.

To adjust how the model behaves or to inspect API details, click the gear icon to open the model settings panel. Here, you can change model parameters and copy the API requests to interact with the model.

For text and reasoning models, you can adjust the number of tokens, temperatiure and top p values. For multimodal models, you can adjust settings specific to each output type such as image resolution, aspect ratio, and number of images to generate, video resolution, frames per second, and motion strength to control how much the subjects or camera move within the scene, and audio duration, sample rate, and voice style:

• Max Tokens: Defines the maximum output tokens a model processes. For model-specific details, see the models page.

  Click to see example responses with different max token values.

  For the prompt “What is the UN?”, here are responses with different max token values:

  Max tokens	Example response
  200	The United Nations (UN) is an international organization that aims to promote peace, security, and cooperation among its member states.
  512	The United Nations (UN) is an international organization that was established in 1945 to promote peace, security, and cooperation among its member states. The UN has 193 member states and is headquartered in New York City. Its goals include maintaining international peace and security, promoting sustainable development, protecting human rights, delivering humanitarian aid, and upholding international law. The UN is composed of several key bodies, including the General Assembly, the Security Council, the Economic and Social Council, the Secretariat, and the International Court of Justice.

• Temperature: Controls the model’s creativity, specified as a number between 0 and 1. Lower values produce more predictable and conservative responses, while higher values encourage creativity and variation. Values are rounded to the nearest hundredth. For example, if you enter a value of 0.255, the value is rounded to 0.26.

  Click to see example responses with different temperature values.

  For the prompt “What color is the sky?”, here are example responses with different temperature values:

  Temperature	Example response
  0.0	The sky is blue.
  0.5	The sky is usually blue during the day, but it can appear different colors depending on weather conditions and time of day.
  0.7	The sky’s color can vary widely. While it’s often perceived as blue, it can also appear pale blue, azure, cyan, or even take on hues of orange, pink, or purple during sunrise or sunset. Clouds, pollution, and atmospheric conditions can further influence its appearance.
  1.0	Ah, the enigmatic canvas above! Some say it’s an endless ocean of cerulean, others a chameleon of hues. Perhaps it’s a mood ring for Mother Nature, shifting from the softest baby blue to the deepest indigo, with detours through fiery oranges and dreamy purples. Or maybe it’s just a figment of our collective imagination, a shared hallucination we call “sky.” What do you think it looks like right now?

• Top P: Defines the cumulative probability threshold for word selection, specified as a number between 0 and 1. Higher values allow for more diverse outputs, while lower values ensure focused and coherent responses. Values are rounded to the nearest hundredth. For example, if you enter a value of 0.255, the value is rounded to 0.26.

  Click to see example responses with different Top P values.

  For the prompt “What color is the sky?”, here are example responses with different Top P values:

  Top P	Example response
  0.1	The sky is blue.
  0.5	The sky is typically blue, but it can change color depending on weather conditions and time of day.
  0.7	The sky’s color varies widely. It’s often blue during clear days, but can appear gray when cloudy, and takes on beautiful hues of orange, pink, and purple during sunrise and sunset. Atmospheric conditions like pollution or dust can also affect its appearance.
  1.0	The sky is a ever-changing tapestry of colors! While we often think of it as blue, it’s really a dynamic canvas that shifts throughout the day. From the soft pastels of dawn to the vibrant azure of noon, and the fiery spectacle of sunset, the sky never ceases to amaze. Sometimes it’s a moody gray, other times a crisp cerulean. And let’s not forget those rare treats like the ethereal green of the aurora borealis or the ominous green tint before a tornado. What’s your favorite sky color?

Evaluate the responses and, if needed, keep adjusting the model settings until the behavior matches what you need.

Compare Models

To compare different foundation models, on the Model Playground page, click Compare Another Model to open the comparison view. Select a model from the dropdown list and toggle Sync Inputs so the same prompt and attachments apply to each model where supported.

Enter your prompt in the text box, add attachments, and press Enter. Compare the responses, and adjust model settings in the model settings panel as needed.
