How to get the best result

Qwen Image 3.0, Alibaba's newest image model: 2K images for 3¢ with strong prompt understanding, and edits from a reference image. Pick instead: nano-banana-2.1 for design layouts and in-image text; flux-1-schnell for 1¢ drafts; gemini-3-pro-image for multilingual text and complex layouts.

Prompting

Describe the subject, the scene, the style and the composition in plain sentences.
For an edit, pass referenceImageUrl and describe only the change.

Settings on Varosity

Always 2K; 3¢ an image, 4¢ as an edit with referenceImageUrl.
aspectRatio 1:1, 16:9 or 9:16; an edit follows the reference image's shape.

Avoid

Readable text in the image: signs come out as made-up lettering (use nano-banana-2.1 for text).
Other shapes such as 4:5 or 21:9: REST /v1/images and MCP generate_image refuse them before anything is charged.

Example prompt

A street food stall at night in Taipei, steam rising from bamboo baskets, neon signs reflected on wet pavement, 35mm photo.
