The Playground is your space to experiment with prompts, models, and settings with no setup required. It is the fastest way to find the right combination before committing to a Flow or Agent.
Think of it as a scratchpad where you can iterate freely, test edge cases, and build confidence in your AI configuration before it goes live.
You are building a customer support chatbot that handles refund requests. Before adding the prompt to a Flow, test it in the Playground:
This kind of rapid iteration helps you catch weak prompts and edge-case issues early, before they reach your users.
Click Playground in the left sidebar. The interface opens immediately with your default model selected, so you can start testing right away.
The Playground has three main areas.
Choose the model you want to test from the dropdown. The models available to you depend on whether you are using platform keys or your own API keys (BYOK).
Not sure which model to start with? Try a general-purpose model like gpt-5 or claude-sonnet-4-6 first, then experiment from there.
Write your system prompt in the editor. You can include template variables like {{customer_name}} or {{order_id}}. The Playground will ask you to fill in values before running.
Template variables are a good way to test how your prompt handles different inputs without rewriting it each time.
Click Advanced Settings to fine-tune model behavior:
Start with a temperature around 0.7 for most use cases. Go lower, around 0.2 to 0.3, when you need consistent responses such as customer support or data extraction. Go higher, around 0.8 to 1.0, for creative tasks such as brainstorming or content generation.
You can keep chatting to test multi-turn conversations. Each message builds on the previous context, just like it would in a deployed Flow or Agent.
Once you have found a prompt and model combination that works, you can save it directly from the Playground without rebuilding anything from scratch.
Use Save as Flow when you have a well-tuned prompt that is ready to become a step in a workflow. Your model, prompt, and settings carry over. If you want to keep building, see Creating and editing Flows.
Use Save as Agent when you need multi-step reasoning with tool use. Your tool attachments and configuration are preserved so the Agent can pick up where you left off. For the next step, see Creating and configuring Agents.
