Prompt Expansion - Custom Node for ComfyUI版本v0.1 (ID: 163138)

ComfyUI Prompt Expansion

Dynamic prompt expansion, powered by GPT-2 locally on your device.

The custom node will analyze your 'Positive prompt' and 'Seed' and incorporate additional keywords, which will likely improve your resulting image.

For example, (from the images above):

Original prompt: Portrait of robot Terminator, cybord, evil, in dynamics, highly detailed, packed with hidden details, style, high dynamic range, hyper realistic, realistic attention to detail, highly detailed

Expanded prompt: Portrait of robot Terminator, cybord, evil, in dynamics, highly detailed, packed with hidden details, style, high dynamic range, hyper realistic, realistic attention to detail, highly detailed, extremely lifelike, digital painting, artstation, illustration, concept art, smooth, sharp focus, 8k

Based on my testing, it's evident that incorporating additional keywords generated by GPT-2 notably improves the quality of the resulting images.

Many thanks to the authors of the Fooocus project for generously providing most of the code.
