### Global Prompt (Optional)

The **Global Prompt** is a system-level instruction that shapes how the model responds across every interaction.

* **Purpose:**\
  Use this field to define consistent behavior, tone, or rules for the AI.
* **How it works:**\
  Any text entered here is prepended to every conversation, influencing responses without needing to repeat instructions each time.
* **Examples:**
  * “Respond in a professional and concise tone.”
  * “Always provide step-by-step explanations.”
  * “Act as a helpful coding assistant specialized in Python.”
* **When to use it:**
  * Enforcing a consistent writing style
  * Setting domain expertise (e.g., legal, medical, technical)
  * Defining response constraints or preferences
* **When to leave it empty:**
  * If you want each conversation to behave independently
  * If instructions will vary frequently between chats

### Input Field

* Enter your global prompt in the text area labeled **“Enter value”**
* Changes take effect immediately for new and ongoing conversations
