Open source alternatives to Hunyuan Image 3.0

By GitHub stars it is Z-Image, with 12,152 stars and a commit on 9 Feb. Choose Z-Image when you need an open model for one consumer GPU; its 6B Turbo version fits in 16 GB of memory, needs 8 steps and uses the Apache 2.0 license. Next come GLM-Image (1,079 stars).

Yes. The code of all 2 is public under Apache 2.0 or MIT, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.

Start from the job you use Hunyuan Image 3.0 for. Choose GLM-Image when your images carry a lot of text; Z.ai built it for accurate text rendering, releases it under MIT, runs it in about 23 GB with CPU offload, and sells API access at $0.015 per image.

All 2: Z-Image and GLM-Image. Each tool's page says what it needs to run.

0 of the 2 we track had a commit in the last 30 days. The quietest is Z-Image, last changed on 9 Feb. A recent commit shows the project is kept up, not that it will stay that way.

Apache 2.0 (1), MIT (1). MIT, BSD and Apache let you change and reuse the code freely.

The hosting. Hunyuan Image 3.0's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
