Using the Playground

The playground is a built-in chat interface for testing your agents interactively. It supports real-time streaming responses and lets you experiment with different configurations without modifying the agent itself.

Starting a Chat​

  1. Navigate to Agents and click on an agent.
  2. The playground opens with the agent's configuration loaded.
  3. Type a message and press Enter or click Send.
  4. Responses stream in real-time via Server-Sent Events (SSE).

Managing Sessions​

  • Create a new session — Click the New Session button in the sidebar to start a fresh conversation.
  • Switch between sessions — Click on a session in the sidebar to load its history.
  • Delete a session — Click the delete icon on a session to remove it and its messages.

Sessions are preserved across page reloads, so you can pick up where you left off.

Configuration Overrides​

In the playground config bar, you can temporarily override:

  • Provider — Test with a different LLM provider.
  • Model — Try a different model. If the model doesn't exist in the dropdown, simply type the correct model name (e.g., gpt-5-mini) and it will be saved for future use.
  • Temperature, Top P, Top K — Experiment with generation parameters.

These overrides apply only to the current playground session and don't modify the agent's saved configuration.

Tool Overrides​

You can temporarily override which tools the agent has access to:

  1. Click the Tools icon in the config bar (next to the configuration button).
  2. A panel shows all available HTTP tools and MCP servers with checkboxes.
  3. Check or uncheck tools to customize what the agent can use for this session.

Tool overrides are temporary — they don't modify the saved agent configuration unless you explicitly save them. For more details, see the Tools guide.

Saving a Configuration​

If you find a combination of overrides that works well, click the Save Config button to save it as a new agent. This includes both configuration overrides (provider, model, parameters) and tool overrides. This lets you quickly iterate on configurations and promote the best ones to reusable agents.
