MiniMax H3 Image Prompt Enhancement

Text-to-image, image editing and independent prompt enhancement.

All models

Platform safety check, enabled by default. Disabling requires account permission; otherwise it stays enabled.

On

Up to 32,000 Unicode characters. Built-in prompt enhancement is billed as input text tokens.

Upload 1–16 references for editing, or optional references for standalone prompt enhancement.

Custom dimensions use 655,360–20,000,000 pixels and ratios from 1:3 to 3:1. Custom size replaces area and aspect_ratio.

No pre-charge. Submit with a positive balance; successful work is billed once using actual usage. The final debit may make your balance negative. Top up before starting another task.

Credits use 6.67 CNY/USD and USD 0.005/credit, rounded to two decimal places.

Prompt enhancement returns text only. It has no 4K discount. Editing an image with the revised prompt runs and bills enhancement again.
