I am a graduate student doing my master's in the Computer Science Department at National Tsing Hua University in Taiwan.

I am interested in improving the performance of Generative AI, focusing on training better models, building efficient and robust systems, and developing useful tools.

I'm currently working on project: HomeDiffusion.
HomeDiffusion seeks to enable pretrained diffusion models on consumer-level hardware. And we already have a usable model: HDM-xut-340M-anime. Which is trained with 1500 GPU hour on 5090.

AI art should look like AI, not humans.
