• AND, OR, NOT operators for combining conditions

Improved Playground Views

December 10, 2025 The Prompt Playground page is now Playgrounds, where you can use your Playground Views! This change allows you to easily navigate to a configuration of the prompt playground you’ve saved. A playground view saves a complete snapshot of your current prompt playground session, allowing you to preserve your work, share configurations with teammates, or return to previous experiments. Here’s what’s saved in a view:

• LLM Config (provider, model selection, model params, custom endpoint settings)
• Prompt Setup (messages, roles, message content, tool and function calls)
• Generated Results (when setup with datasets)
• Connected Datasource (dataset or span)

If you want to start a playground from scratch, you can create a view using the + Playground button at the top of the Playgrounds page.
