Practical Implementations: Real-World Coding Examples

Automated Image Generation Workflow

from comfyui import Workflow, Node

# Instantiate workflow
workflow = Workflow()

# Define nodes for image synthesis
text_input = Node("TextInput", text="A futuristic metropolis at sunset")
stable_diffusion = Node("StableDiffusion")
image_output = Node("ImageOutput")

# Establish node connectivity
workflow.add_node(text_input)
workflow.add_node(stable_diffusion)
workflow.add_node(image_output)
workflow.connect(text_input, stable_diffusion)
workflow.connect(stable_diffusion, image_output)

# Execute workflow
task_result = workflow.run()

Leveraging ComfyUI-Copilot for Workflow Refinement

from comfyui_copilot import Copilot

# Initialize Copilot instance
copilot = Copilot()

# Solicit workflow optimization insights
suggestions = copilot.optimize_workflow("High-resolution portrait synthesis")
print(suggestions)
