I'm looking for an open source image model that can natively produce 4K, but I couldn't find it before. The native output of most open source models stops at around one million pixels. If you want to achieve 4K, you have to use a super-resolution model to enlarge the model. Details can be "guessed", and cloth textures and small characters are most easily exposed.

MiniMax H3 Image fills this gap. It directly outputs 4096×4096, about 16 million pixels, and takes about 10 seconds to take a single picture. The weight is placed on Hugging Face, and the three capabilities of text drawing, image reference, and image editing are available.

After getting the weight, you can do a lot more than using the API:

  • Use your own product pictures and character setting pictures to make fine adjustments to let the model understand your brand and character.
  • If it is run on the intranet, design drafts and unreleased new product images will not be released to the company.
  • Connect to the existing ComfyUI workflow and connect it with cutout and coloring nodes

But before deploying, there are three things I suggest you think about clearly.

First, the license.Open weight does not mean casual commercial use. The terms of use in the model card must be read one by one, especially the scope of commercial use and signature requirements.

Second, hardware.4K means that the number of pixels in a picture is 16 times that of 1024×1024, and the memory and time required for inference will increase accordingly. The 10 seconds given by the official are based on their own service environment. You must actually test it on your graphics card. Don't use the numbers from the press conference for scheduling.

Third, is it worth it?The standard version of 4K API is about US$0.069 per card, and about US$0.034 in the first week. A team that produces hundreds or thousands of pictures a month may not be able to save the money to build its own machine for several years.

Therefore, the more realistic order is: first use the ready-made service to find out the effect, confirm that this model is suitable for your own graph, and then decide whether to deploy it.

If you don’t want to mess with the environment, MiniMax’s official partner sites PixPix and PixTV can already directly experience H3 Image 4K, and you can open the web page to produce pictures. Once the effect is confirmed, it’s not too late to go to Hugging Face and adjust the weight.

MiniMax has released the image model this time. What kind of fine-tuned version the open source community will produce in the next few weeks is something more worth pursuing than the official demonstration.
