OpenAI Playground
Browser-based environment from OpenAI for testing and prototyping with GPT models before deploying via the API.
About
OpenAI Playground is an interactive web interface that lets developers explore model behavior through chat, completion, and assistants modes without writing any code. You can adjust parameters such as temperature, max tokens, and system prompts in real time to see how they affect outputs. It is intended as a sandbox for prompt engineering and model selection before building production applications. Access requires an OpenAI account; usage is billed at standard API token rates, with free credits available to new accounts.
