The Playground lets you talk to any of your endpoints before you wire it into a product. It is the quickest way to check how a fine-tuned version or a base model answers.

The Playground: a conversation with an endpoint, with a system prompt set on the right.

​
Chat with an endpoint

1

Pick an endpoint

Choose one of your running endpoints in the Endpoint card. Base-model endpoints are marked (base). Open endpoint takes you to its page.
2

Adjust the settings (optional)

Add a System prompt with instructions for every reply, and set the Temperature and Max tokens.
3

Send a message

Type a message and press Enter to send it. Shift+Enter adds a new line. Click Clear to start over.
If you have no running endpoint, the Playground shows links to deploy one. See Endpoints.
Getting an empty reply? Some models think before they answer, and that thinking counts toward Max tokens. If the limit is low, the model can use it all up before it writes the answer. Raise Max tokens (the default of 512 is enough for most questions) and send the message again.
Messages you send here are real requests to your endpoint, so the endpoint must be running. Comparing a fine-tuned version side by side with its base model is marked Coming soon.
