Install the required Python library:

pip install replicate

1. Download the latest release from GitHub Releases

2. Extract the release

   This will create a folder named dream-prompter-{version} (e.g., dream-prompter-1.2.0)

3. Move to your GIMP plugins folder with the correct name:

   Rename and move the extracted folder to exactly dream-prompter in your GIMP plugins directory:

• Linux: ~/.config/GIMP/3.0/plug-ins/dream-prompter/ (Snap: ~/snap/gimp/current/GIMP/3.0/plug-ins/dream-prompter/)
• Windows: %APPDATA%\GIMP\3.0\plug-ins\dream-prompter\
• macOS: ~/Library/Application Support/GIMP/3.0/plug-ins/dream-prompter/

Example for Linux:

# Extract creates dream-prompter-1.2.0/
unzip dream-prompter-1.2.0.zip
# Move to correct location with correct name
# Replace ~/.config/GIMP with ~/snap/gimp/current/GIMP if you installed GIMP via Snap
mv dream-prompter-1.2.0 ~/.config/GIMP/3.0/plug-ins/dream-prompter

4. Make executable (Linux/macOS only):

   # Replace ~/.config/GIMP with ~/snap/gimp/current/GIMP if you installed GIMP via Snap
   chmod +x ~/.config/GIMP/3.0/plug-ins/dream-prompter/dream-prompter.py

5. Restart GIMP

Building translations (optional): If you need languages other than English, run python3 scripts/build-translations.py in the plugin directory after installation.

To install Dream Prompter on Arch Linux, you can install it from the AUR.

yay -S dream-prompter

1. Find your GIMP plugins directory (paths listed above) If you installed GIMP via Snap, use ~/snap/gimp/current/GIMP as the base directory instead of ~/.config/GIMP.

2. Create plugin directory:

   # Replace ~/.config/GIMP with ~/snap/gimp/current/GIMP if you installed GIMP via Snap
   mkdir -p ~/.config/GIMP/3.0/plug-ins/dream-prompter/

3. Copy all Python files and the models directory:

   # Replace ~/.config/GIMP with ~/snap/gimp/current/GIMP if you installed GIMP via Snap
   cp *.py ~/.config/GIMP/3.0/plug-ins/dream-prompter/
   cp -r models ~/.config/GIMP/3.0/plug-ins/dream-prompter/

4. Build and install translations (Optional):

   python3 scripts/build-translations.py
   # Replace ~/.config/GIMP with ~/snap/gimp/current/GIMP if you installed GIMP via Snap
   cp -r locale ~/.config/GIMP/3.0/plug-ins/dream-prompter/

5. Make executable:

   # Replace ~/.config/GIMP with ~/snap/gimp/current/GIMP if you installed GIMP via Snap
   chmod +x ~/.config/GIMP/3.0/plug-ins/dream-prompter/dream-prompter.py

The plugin is organized into focused modules with a clean model-driven architecture:

• dream-prompter.py - Main GIMP plugin entry point
• dialog_gtk.py - GTK user interface components
• dialog_events.py - Event handling and user interactions
• dialog_threads.py - Background processing and threading
• api.py - Replicate API integration
• integrator.py - GIMP-specific operations
• settings.py - Configuration persistence
• i18n.py - Internationalization support

• models/__init__.py - Base model classes and registry system
• models/factory.py - Model factory for centralized model management
• models/flux_pro.py - Flux 2 Pro model implementation
• models/gpt_image.py - GPT Image 1.5 model implementation
• models/imagen.py - Imagen 4 model implementation
• models/nano_banana.py - Nano Banana model implementation
• models/nano_banana_pro.py - Nano Banana Pro model implementation
• models/qwen_image.py - Qwen Image model implementation
• models/qwen_image_edit_plus.py - Qwen Image Edit Plus model implementation
• models/seedream.py - Seedream 4.5 model implementation
• models/stable_diffusion_large_turbo.py - Stable Diffusion 3.5 Large Turbo model implementation

The model system provides a clean abstraction for AI models, making it easy to:

• Add new models by implementing the BaseModel interface
• Validate inputs using model-specific limits and constraints
• Build API requests with model-specific parameter formats
• Maintain consistency across the entire plugin

To add support for a new Replicate model:

1. Create a new model file in the models/ directory (e.g., models/my_model.py)
2. Implement the BaseModel interface:

from . import BaseModel, OutputFormat, register_model

class MyModel(BaseModel):
    @property
    def name(self) -> str:
        return "my-account/my-model"

    @property
    def display_name(self) -> str:
        return "My Custom Model"

    # Implement other required properties...

    def build_generation_input(self, prompt, reference_images=None, **kwargs):
        # Implementation for generating...
        pass

    def build_edit_input(self, prompt, main_image, reference_images=None, **kwargs):
        # Implementation for editing...
        pass

# Register the model
my_model = MyModel()
register_model(my_model)

3. Import the model in models/factory.py to ensure it's loaded
4. The model is now available throughout the plugin with automatic validation and UI updates

The nano_banana.py file serves as a complete reference implementation.
