Judging Criteria
Two tracks, one for workflow+content the workflow generates, the other for development (custom nodes, product that uses ComfyUI)
Performance Impact: Measurable improvements in speed, memory, or quality
Community Value: How many users would benefit from this solution
Technical Execution: Code/workflow quality and implementation approach
Demo/Workflow Quality: Clear presentation of the problem solved
Extra:
RTX Innovation: The top participants who use TensorRT, RTX Remix, or NVIDIA SDKs will get an extra $500
Example Judging:
Workflow:
"I created a creative video with Veo" -> ❌ creative on the content and prompt is great, but the workflow complexity is too low
"I created a video using an insane workflow, but the result is messy and low quality" -> ❌ The content itself also matters.
Development:
"I built a Gradio app using the Comfy backend to do image-to-image" -> ❌ Great work, but a bit too straightforward.
"I built a custom node that resizes the image, but it's super slow." -> ❌ Simple idea and lacks performance.
