擅长场景与写法对照

GPT Image 2

Conversational, iterative editingUnderstanding of natural-language descriptionsPhoto stylization & local replacementChinese prompts work directly

It responds better to conversational descriptions than to stacks of parameter keywords. When editing an image, saying "change the background to…" is more efficient than rewriting the whole prompt.

Ideogram 4

Poster and headline typographyGraphic design and brand visualsCharacter sheets and multi-view turnaroundsAccurate rendering of complex text

Lock the wording in quotes, then describe the type's character (sans, handwritten, serif) and the hierarchy of the layout. Don't push more than three blocks of text into one image — they start crowding each other.
