Smart Variable Fill

Smart Variable Fill uses AI to automatically generate reasonable values for empty variables, suitable for quickly testing and validating variable-based prompts.

When to Use

  • Prompt has multiple variables, but you only want to fill core variables
  • Want to quickly test prompt results without manually filling all variables
  • Unsure what value a variable should have

How to Use

Batch Fill

  1. Fill core variables in the variable panel (e.g., "Product Name")
  2. Click the Smart Fill Variable Values button at the top of the variable panel
  3. AI automatically generates values for all empty variables
  4. Preview the generated results
  5. Confirm application

Single Variable Fill

  1. Find the target variable in the variable panel
  2. Click the variable row's dropdown menu
  3. Select Smart Fill option
  4. AI generates a value for only this variable
  5. Preview and confirm

How It Works

Variable Identification

  • Only fills empty variables: Already filled variables won't be overwritten
  • Filled variables serve as context: AI references filled variables to generate coordinated values

AI Derivation Logic

AI derives variable values based on:

  • Prompt's theme and style
  • Variable's semantic role in the prompt
  • Scene composition implied by filled variables
  • Mutual coordination between generated values

Preview Dialog

After generation, a preview dialog appears showing:

  • Generated value for each variable
  • Generation reason
  • Confidence level
  • Editable generated results
  • Option to select which variables to apply

Prerequisites

  • Evaluation model must be configured (set in Model Management)
  • Prompt cannot be empty

Use Cases

Quick Testing

Prompt: Write an article about {{topic}}, targeting {{audience}}, in {{style}} style

Manually fill: topic = Artificial Intelligence
Smart fill: audience = Tech enthusiasts, style = Professional but easy to understand

Scene Building

Prompt: Write launch copy for {{product}}, targeting {{user_group}}, emphasizing {{core_selling_point}}

Manually fill: product = Prompt Optimizer
Smart fill: user_group = AI developers and prompt engineers, core_selling_point = One-click prompt optimization

Common Questions

Why weren't any values generated?

  • Check if an evaluation model is configured
  • Confirm the prompt is not empty
  • Check if all variables are already filled (in batch mode)

How to improve generation quality

  • Be specific when filling core variables
  • Variable names should be semantic (e.g., "product_name" not "variable1")
  • The prompt itself should clearly describe the variable's purpose

What if generated values are inappropriate?

  • Edit generated results in the preview dialog
  • Uncheck variables you don't want to apply
  • Regenerate if needed; each run may produce different results
