MiniMax open-sources H3-Image: 16MP 4K images in seconds

On November 10, MiniMax officially released and open-sourced the image generation model H3-Image, with weights available on Hugging Face under a community license. The company calls it the strongest open-weights image model to date.

Confirmed

• Speed and resolution: 4K×4K images generated in 10–20 seconds, with output up to 16 megapixels (16MP)
• Multiple reference images: supports up to 16 reference images
• Architecture and form: built on the architecture of MiniMax's open-source video model H3; it's a unified generation-and-editing model that, per community author @RisingSayay, uses 6-step distillation to directly output 16MP images, with output resolutions starting from 4096×4096 (1:1)
• Ecosystem: besides the standard version, there's an H3 Image Highspeed variant, available on Runware on day one
• Quality claims: the official emphasis is on detail and photorealism, shedding the typical "AI look"

Why it matters

• Open-weights high-resolution image models have generally been limited in either speed or resolution; H3-Image combines native 16MP output with 10–20 second generation, lowering the barrier to high-quality image generation
• The unified generation-editing design with support for 16 reference images makes it competitive for multi-image workflows requiring character/style consistency
