Strengths & Prompt-Writing Comparison

HiDream I1

Photoreal and illustration alikeFast generationOpen-source, self-hostable and tunableConcept boards and batch drafts
It reads structured descriptions well — write subject, environment, lighting and style as separate clauses. Keep style words to two or three; stack more and they fight each other.

Nano Banana Pro

Consistent characters across multiple reference imagesIn-image text layout & renderingFollows long, structured prompts closelyFine-grained layout for e-commerce & infographics
Feel free to use structured formats (JSON, sectioned lists) when writing prompts — it parses hierarchical instructions much better than piles of short phrases. When text needs to appear in the image, write the exact wording in quotes.
