Describe the camera position, light direction and space needed for text. For an edit, put the product reference first and identify the background reference separately.

What to know before you start
Choose batch size deliberately
MiniMax H3 Image can generate ten images at once. Start with one when testing a brief.
Size controls work in two modes
Give MiniMax H3 Image an area and ratio, or exact dimensions. These modes cannot be combined. Area selects an approximate pixel budget; it does not specify the two sides. Choose exact dimensions when an export must fit a canvas. Keep the aspect ratio between 1:3 and 3:1 in either mode.
Enhancement and editing
MiniMax H3 Image always enhances edits. Without enhancement, text generation needs fixed framing and reads roughly 4096 prompt tokens.
Prepare accessible references
MiniMax H3 Image needs public image URLs. Order references as your prompt names them.
