zimage

Type a prompt in Chinese or English and zimage returns an image, with no login and no watermark on the result.

That is the whole workflow on the hosted site at zimage.run. zimage is a free, open source AI image generator that turns text into photorealistic pictures, posters and photography-style shots.

Speed is the main selling point.

Generation takes under a second on an H100 and roughly 5 to 10 seconds on a 16GB GPU, so you can run it on consumer hardware instead of renting a server.

If you deploy it locally, plan on a card with 16GB of VRAM.

The online version skips that requirement.

Text rendering is a strength for both Chinese and English, which matters for posters and signage where lettering usually goes wrong.

The bilingual support also covers cultural nuances in prompts.

Output quality is described as comparable to leading commercial models, though you should judge that on your own prompts.

The Apache 2.0 license allows commercial use, and generated images carry no copyright restrictions.

For a free text to image tool, that is a clear and simple deal.
