# Playground

> Interactive testbed for every model in the catalog. Chat with LLMs, run multimodal models, and launch workflows.

The Playground is an interactive testbed for any model in the [Model Hub](/model-quickstarts/text/overview). Three modes are exposed as tabs at the top:

* **LLM**: text and chat models.
* **Multimodal**: image, video, audio, and vision models.
* **Workflow**: launches the visual workflow runner for saved [Studio workflows](/gmi-studio/gmi-studio-user-manual/introduction).

Top-right links: **Model Details** (jumps to the current model's catalog page) and **Tooling in docs** (this site).

## LLM mode

A model selector above the chat (default *Gemini 3.5 Flash*). Selecting a new model routes to `/playground/llm/<uuid>`.

The left settings panel exposes the common LLM controls:

| Control           | Default                       | Notes                  |
| :---------------- | :---------------------------- | :--------------------- |
| Temperature       | 0.5                           | Sampling temperature   |
| Max Tokens        | 4096                          | Per-response cap       |
| Top K             | 1                             | Top-K sampling         |
| Top P             | 0.9                           | Nucleus sampling       |
| Frequency Penalty | 0                             |                        |
| Presence Penalty  | 0                             |                        |
| Stream            | On                            | Token streaming toggle |
| System Prompt     | "You are a helpful assistant" | Editable               |

The chat surface fills the rest of the screen with a "Type your message" composer at the bottom.

## Multimodal mode

Pick an image, video, audio, or vision model. The UI adapts per model: prompt textarea, asset upload slot, and model-specific parameters (e.g. duration for video, voice ID for TTS).

## Workflow mode

Opens an embedded workflow runner so you can execute saved Studio workflows without leaving the Playground.

## Next steps

* Browse the [Text catalog](/model-quickstarts/text/overview), [Image catalog](/model-quickstarts/image/overview), [Video catalog](/model-quickstarts/video/overview), or [Audio catalog](/model-quickstarts/audio/overview) for model IDs and API examples.
* Build a multi-step pipeline in [GMI Studio](/gmi-studio/gmi-studio-user-manual/introduction).
