# Debugging Prompts with Playground

<Info>Currently, only ChatGPT is supported</Info>

Helicone's 'Playground' feature offers a platform for debugging your 'prompt'. This tool enables you to test your prompt and swiftly observe the model's output for minor adjustments within the Helicone environment. Here's a step-by-step guide on how to use it:

1. Open a request.
