fal.ai Image Generation & Editing Skill

Professional AI-powered image workflows using fal.ai's state-of-the-art models including FLUX, Recraft V3, Imagen4, and more.

Three Modes of Operation

1. Text-to-Image (fal-text-to-image)

Generate images from scratch using text prompts

2. Image Remix (fal-image-remix)

Transform existing images while preserving composition

3. Image Edit (fal-image-edit)

Targeted inpainting and masked editing

When to Use This Skill

Trigger when user:

• Requests image generation from text descriptions
• Wants to transform/remix existing images with AI
• Needs to edit specific regions of images (inpainting)
• Wants to create images with specific styles (vector, realistic, typography)
• Needs high-resolution professional images (up to 2K)
• Wants to use a reference image for style transfer
• Mentions specific models like FLUX, Recraft, or Imagen
• Asks for logo, poster, or brand-style image generation
• Needs object removal or targeted modifications

Quick Start

Text-to-Image: Generate from Scratch

# Basic generation
uv run python fal-text-to-image "A cyberpunk city at sunset with neon lights"

# With specific model
uv run python fal-text-to-image -m flux-pro/v1.1-ultra "Professional headshot"

# With style reference
uv run python fal-text-to-image -i reference.jpg "Mountain landscape" -m flux-2/lora/edit

Image Remix: Transform Existing Images

# Transform style while preserving composition
uv run python fal-image-remix input.jpg "Transform into oil painting"

# With strength control (0.0=original, 1.0=full transformation)
uv run python fal-image-remix photo.jpg "Anime style character" --strength 0.6

# Premium quality remix
uv run python fal-image-remix -m flux-1.1-pro image.jpg "Professional portrait"

Image Edit: Targeted Modifications

# Edit with mask image (white=edit area, black=preserve)
uv run python fal-image-edit input.jpg mask.png "Replace with flowers"

# Auto-generate mask from text
uv run python fal-image-edit input.jpg --mask-prompt "sky" "Make it sunset"

# Remove objects
uv run python fal-image-edit photo.jpg mask.png "Remove object" --strength 1.0

# General editing (no mask)
uv run python fal-image-edit photo.jpg "Enhance lighting and colors"

  PROMPT                    Text description of the image to generate

Options:
  -m, --model TEXT         Model to use (see model list above)
  -i, --image TEXT         Path or URL to reference image for style transfer
  -o, --output TEXT        Output filename (default: generated_image.png)
  -s, --size TEXT          Image size (e.g., "1024x1024", "landscape_16_9")
  --seed INTEGER           Random seed for reproducibility
  --steps INTEGER          Number of inference steps (model-dependent)
  --guidance FLOAT         Guidance scale (higher = more prompt adherence)

Authentication Setup

Before first use, set your fal.ai API key:

export FAL_KEY="your-api-key-here"

Advanced Examples

High-Resolution Professional Photo

uv run python fal-text-to-image \
  -m flux-pro/v1.1-ultra \
  "Professional headshot of a business executive in modern office" \
  -s 2048x2048

Logo/Typography Design

uv run python fal-text-to-image \
  -m recraft/v3/text-to-image \
  "Modern tech startup logo with text 'AI Labs' in minimalist style"

Style Transfer from Reference

uv run python fal-text-to-image \
  -m flux-2/lora/edit \
  -i artistic_style.jpg \
  "Portrait of a woman in a garden"

Reproducible Generation

uv run python fal-text-to-image \
  -m flux-2 \
  --seed 42 \
  "Futuristic cityscape with flying cars"

Model Selection Logic

The script automatically selects the best model when -m is not specified:

1. If -i provided: Uses flux-2/lora/edit for style transfer
2. If prompt contains typography keywords (logo, text, poster, sign): Uses recraft/v3/text-to-image
3. If prompt suggests high-res needs (professional, portrait, headshot): Uses flux-pro/v1.1-ultra
4. If prompt mentions vector/brand: Uses recraft/v3/text-to-image
5. Default: Uses flux-2 for general purpose

Output Format

Generated images are saved with metadata:

• Filename includes timestamp and model name
• EXIF data stores prompt, model, and parameters
• Console displays generation time and cost estimate

Troubleshooting

| Problem | Solution | |---------|----------| | FAL_KEY not set | Export FAL_KEY environment variable or create .env file | | Model not found | Check model name against supported list | | Image reference fails | Ensure image path/URL is accessible | | Generation timeout | Some models take longer; wait or try faster model | | Rate limit error | Check fal.ai dashboard for usage limits |
