MiniMax H3 Image is a new 33.1B image model that generates and edits pictures at 16 megapixels, 4096 × 4096 or a matching wide or tall size, in only 6 sampling steps on your own NVIDIA GPU, with no upscaler. Our SECourses ComfyUI installer V150 ships two ready presets for it, Text To Image 16 MP and Image Edit Up To 16 Images, with every model and setting already chosen. MiniMax's official prompt enhancer runs locally inside them in three modes (reasoning, fast and off): it turns a short idea in any language into the detailed caption the model was trained on, picks the aspect ratio, and a box shows the exact prompt the model received. The SECourses Model Downloader V190 fetches every model file into the right folders from one bundle. In this mini tutorial a rusted, moss-covered Volkswagen Beetle is restored with one plain sentence, 9 typed words become a 16 MP photo of a fox, and you see a room furnished from 4 photos, letter-perfect posters and 1 MP vs 4 MP vs 16 MP.

You will learn how to open the MiniMax H3 Image text to image preset from the Presets folder with Ctrl+O, write a short idea in box 1 in any language, keep the recommended 16 MP output size, use the prompt enhancer in reasoning mode for the best captions or fast mode for quick tries, switch it off when you write a long caption yourself, read the exact prompt the model received, and inspect the result at full size. In the image edit preset you add your photo to the gallery as @image1, write the change as one plain sentence with no mask, say what must stay the same (the forest, the light, the camera angle), and name more reference images with @image2 and @image3. Finally you set up the route yourself: download the ComfyUI V150 zip from our Patreon post, extract it over your ComfyUI folder, run the update file, install bundle 100 with the bundles installer, then open the MiniMax-H3 Core Bundle in the Model Downloader (4 files for images, about 44 GB) or the Low VRAM Bundle, which brings a smaller version of the image model.
Main topics include MiniMax H3 Image, ComfyUI presets, text to image, AI photo restoration, multi-image editing with @image tags, the local prompt enhancer, automatic aspect ratio, 6-step sampling, native 16 MP without an upscaler, RTX 5090 speed and lower VRAM use.

Measured numbers and their conditions: on an RTX 5090 with the models loaded, 6 steps, prompt encoding and decoding included and the prompt enhancer not included, 1 MP took 3.4 s, 4 MP 5.7 s and 16 MP 15.7 s. With ComfyUI limited to 12 GB of the same card's memory, a 16 MP image still finished in 19.5 s, the rest streaming from system RAM; a real 12 GB card computes slower. On camera, the fast enhancer mode made a second 16 MP fox in under half a minute from the click, and reasoning mode adds about a minute for the best captions.
This video is for ComfyUI users and AI image makers with an NVIDIA GPU who want the newest local image model at its full 16 megapixel quality without collecting files, nodes and settings by hand: open a preset, write one sentence and click Run. If ComfyUI is new for you, start with the installation tutorial linked above; if it is already installed, the update tutorial shows the zip update step by step.

10 November 2026 Update V150
Presets Folder Content In Latest Zip File
MiniMax H3 Image is here: 16-megapixel images in 6 steps. Two new presets turn a few words into images up to 6272 pixels wide and edit your photos with up to 16 images at once. MiniMax's own prompt enhancer runs locally inside the presets: a short idea in any language becomes the detailed caption the model was trained on, and the enhancer even picks the best shape for your image.
Real runs of the new presets:
Every image in this post comes from a real run of the shipped presets with their default settings.
The complete Presets folder of V150, the new ones marked NEW:
To run them, download the MiniMax-H3 Core Bundle. It now includes MiniMax H3 Image, its VAE and the prompt enhancer model; the text encoder is the one MiniMax H3 video already uses, so H3 users download only the new files:
Both new presets use this one bundle. The MiniMax-H3 Low VRAM Bundle has the smaller W4A8 versions.
NEW PRESET — TEXT TO IMAGE AT 16 MEGAPIXELS
"MiniMax H3 Image - Text To Image 16 MP - 6 Steps - 261110"
Type an idea, press Run, get a 16-megapixel image. The prompt enhancer writes the full description and chooses the aspect ratio, from tall posters to 21:9 panoramas. A snow leopard from one sentence, at 5024 x 3360:
It writes text you can read. A travel poster with two exact lines of lettering, 3072 x 5472:
Panoramas come out in one piece, with no upscaler. Asked for a wide view, the enhancer chose 21:9, 6272 x 2688; below it, three details at their real pixels:
Fine detail at 4096 x 4096. Open it full size and read the screw slots and the jewels:
Where to find it: open the preset, write your idea in the gallery box and press Run:
The box under the result shows the exact prompt the model received. Set the enhancer to Off to use your own long caption; our new MiniMax H3 Image LLM guide in the zip makes ChatGPT, Claude or Gemini write one for you.
1 MP VS 4 MP VS 16 MP
Why 16 MP is the default. The same caption and seed at three sizes, with the face from each cropped to the same share of the frame:
16 MP has sixteen times the pixels of 1 MP, and it uses them: fur, whiskers and frost that 1 MP can only blur. It stays fast, too. Seconds per image on an RTX 5090, also with ComfyUI limited to 24, 16 or 12 GB of its memory:
A 16 MP image takes about 16 seconds with all memory and about 20 seconds when ComfyUI may use only 12 GB; the rest streams from system RAM. Lower the size in 02 OUTPUT SIZE whenever you want a quick draft.
NEW PRESET — IMAGE EDIT WITH UP TO 16 IMAGES
"MiniMax H3 Image - Image Edit Up To 16 Images - 6 Steps - 261110"
Edit your photo with one sentence. Add the image, write the change in any language and press Run. The prompt enhancer looks at your images and writes the full edit description, and the result keeps your photo's shape at 16 MP. A moss-covered wreck comes back to life, while the forest, the branches and the camera stay:
Combine many images. An empty room and three product photos, named @image1 to @image4 in the instruction: the exact armchair, lamp and plant land in the unchanged room:
Where to find it: open the preset, add your images to the gallery, write the change and press Run:
Leave the gallery empty and it works as a text to image preset, so both presets do both jobs.
BUILT IN, LIKE ALL OUR PRESETS
- Batches: + Prompt adds more prompts in a row, and a folder of .txt files runs one image per file.
- The prompt enhancer in three modes: official with reasoning (best), fast without reasoning, or off.
- Optional LoRA stack, shared seed and images per prompt.
- Less memory: pick the W4A8 model in the same loader; BF16 is there for original precision.
