Make a 16 megapixel picture from a prompt, or edit a picture in plain words. For an edit, you can give MiniMax H3 Image up to seven more pictures and tell it what to take from each one.
<h3>How to use it</h3>
<ol>
<li>Drop the workflow into ComfyUI and press Run. It opens with a full prompt, so you get a picture right away.</li>
<li>For your own picture, write a full description. Or turn Auto prompt on and write a few words: a writer turns them into the long description the model wants.</li>
<li>To edit, turn Edit a picture on, load your picture and write the change, for example “Make it snow.”</li>
<li>For a reference, connect an image loader to picture 2 on Write the prompt. Add more in order through picture 8. Name the picture in your request, for example “Put the jacket from picture 2 on the woman in picture 1.”</li>
<li>Size picks 4 MP or 16 MP. Fast runs 2 steps instead of 6. Upscale the result doubles a 4 MP picture with SeedVR2.</li>
</ol>
<h3>What you need</h3>
Update ComfyUI and <a target="_blank" href="https://github.com/ausboss/ComfyUI-AusBoss" rel="ugc">AusBoss nodes</a> first. MiniMax H3 Image support was added to ComfyUI on 2026-11-10, after version 0.44.0, so you need a build newer than that. This version ran on AusBoss nodes 2.22.0. The workflow opens on High VRAM.

<h3>Tips</h3>
<ul>
<li>On an RTX 5090 a new 16 MP picture took about 22 seconds and a 16 MP edit about 35. At 4 MP an edit took about 12.</li>
<li>Put any words that should appear in the picture in quotes. Signs and posters spell them right. Small text far from the subject can still come out as nonsense.</li>
<li>Leave Auto prompt off when your prompt is already a full description. In our runs of the opening prompt, rewriting it tangled the hands.</li>
<li>For an edit, say what should stay the same as well as what you want to change.</li>
<li>Fast frames a little tighter and small words can come out wrong. Leave it off for posters and covers.</li>
