Compared to other text-to-image models, it is smaller (with only 520M parameters), making it highly suitable for deployment on mobile devices. Its main features include: 1) Image generation based on text; 2) Quick generation, completing in 0.5 seconds; 3) Compact parameter size, just 520M; 4) Generation of high-quality images. Its primary usage scenarios include content creation, artistic creation, game development, and app development, among others. Example uses include: generating a picture of blooming roses by inputting 'Blossoming rose,' generating a picture of a golden retriever joyfully running by inputting 'Golden retrievere frolicking run,' and generating a Martian landscape by inputting 'Martian scenery, outer space.' Compared to other large models, it is more suitable for deployment on mobile devices.
