Fooocus automatically handles SDXL model loading and optimization. Check out our documentation for model management tips.

Fooocus includes powerful prompting features that give you maximum creative control over your image generation.

Wildcards

Use wildcards to add randomness and variation to your prompts. Simply use __wildcard_name__ syntax, and Fooocus will randomly select from predefined options.

Example: __color__ flower
Result: Randomly selects from color.txt wildcard file

Wildcard Capabilities

• Nested Support: Use wildcards within wildcards
• Multiple Wildcards: Combine multiple wildcards per prompt
• Selection Options: Ordered or random selection
• Custom Files: Create your own wildcard files

Learn more about wildcards in our Advanced Features page.

Array Processing

Generate multiple variations by using array syntax in your prompts. Process arrays from left to right, creating separate images for each element.

Example: [[red, green, blue]] flower
Result: Generates 3 images, one for each color

Array Features

• Multiple Arrays: Use several arrays in one prompt
• LoRA Integration: Supports inline LoRAs in arrays
• Batch Generation: Automatic batch processing

Inline LoRAs

Apply LoRAs directly in your prompt using simple syntax. No need to configure LoRAs separately - just include them in your prompt.

Example: flower <lora:sunflowers:1.2>
Result: Applies sunflowers LoRA with 1.2 strength
