About H3 Image

H3 Image at h3-image.co is an independent online studio for the MiniMax H3 Image model. You write a prompt or upload reference images in your browser, and get back an image up to 4K, without installing anything or running the model on your own GPU.

Who we are

H3 Image is built and run by a small independent team. We write the guides, use cases and FAQ on this site, test the prompts we publish, and answer support email ourselves.

H3 Image is not affiliated with MiniMax. MiniMax made the H3 Image model; we build the website, the editor and the credit system around it.

What we do

• Generate: turn a text prompt into an image at 1K, 2K or 4K, in the aspect ratio you pick.
• Edit: change an image with a prompt, using up to 16 reference images.
• Show the cost first: every run shows its credit cost before you start, and failed runs refund their credits automatically.
• Keep your work: your images and prompts are saved in My creations until you delete them.

How it works

Images are produced by the MiniMax H3 Image model, which we reach through a third-party model provider (currently kie.ai). The site runs on Cloudflare, payments go through Stripe, and you can sign in with Google. The Privacy Policy lists what each of them receives.

Facts about the model on this site come from MiniMax's own announcement and model card. When those change, we update our pages.
