• example workflow for safetensors

review

• should set the output image size according to the model stated, i.e., 1024x1024 or 512x512
• pixart-xl-2-1024-ms and pixart-sigma-xl-2-1024-ms are recommended (with 1024x1024 size)
• small size model but good quality pictures; and t5 encoder allows you inputting short description or sentence instead of tag(s)
• more quantized versions of t5xxl encoder can be found here
• upgrade your gguf-node (see the last item in reference list below) to the latest version for pixart model support
