Prompts provide instructions and inputs for a Large Language Model (LLM) beyond the standard user-provided chat input. In this example, the prompt describes the LLM's role and persona.\n\n## Quick start\n1. Configure your **Model Provider** with your API credentials.\n2. Open the **Playground** to start the chat and run the flow.\n\n## Next steps\nChange the prompt template, model, or model settings, such as **Temperature**, and then see how the responses change with these different inputs.\n\ud83d\udca1 Some component settings are hidden by default; to view all settings click **Controls** in each component's header menu.\n\ud83d\udca1 You can use curly braces to create variables in your template, such as `{variable}`. These can be populated from other components, with Langflow global variables, or at runtime.",
