Big Love Zuna is a fine-tune of Z-Image-Base. It produces a more photorealistic look, more diverse faces and better skin (with the right prompt and seed). You can run it locally with ComfyUI and Forge Neo as well as online on Tensor Art. The fp8 version produces more noise thus may sometimes look more realistic, but details are not as good. Most of the showcase images have a ComfyUI txt2img workflow embedded. The rest offers Forge Neo metadata.

Settings: 8 steps, cfg1, Euler sampler, Normal or Simple scheduler, 832x1216, 1024x1536 or 1280x1920

Big Love License

Big Love SDXL versions are licensed under CreativeML Open RAIL++M (dated July 26, 2023), the Big Love Z-Image versions are licensed under Apache 2.0, and the Big Love Klein versions are licensed under the FLUX Non-Commercial License (Black Forest Labs Inc.), with the following additional terms:

For clarity, the following version tiers are defined:

Restricted versions: Ultra, Hyper, Klein, Zia, Zuna

Open versions: Pony, XL, Photo, Insta, Lust, ZT

1. You may use Big Love without crediting the creator.

2. You may sell the images that it generates.

3. You may only run the official Big Love versions of the SubtleShader account on Civitai and Tensor Art. Running it on other public or shared servers commercially (including other Civitai and Tensor Art accounts) requires a separate license or permission from the creator.

4. You may not sell this model or merges of this model.

5. You may not merge, share merges of, or share LoRA extractions incorporating Restricted versions. You may merge and share merges of Open versions.

6. When sharing the allowed merges of Open versions, as well as finetunes of them, you must apply these same additional license terms.

7. Redistribution of Restricted versions is prohibited. They may only be obtained from official sources designated by the creator.

8. All use-based restrictions of the CreativeML Open RAIL++M license apply to SDXL versions and their derivatives. All use-based restrictions of the FLUX Non-Commercial License apply to Klein versions and their derivatives.

9. Any restrictions in these additional terms may be waived only with explicit written permission from the creator.

TLDR: This is basically the same license as before (just stated more clearly), so nothing changes for the Pony, XL, Photo, Insta, Lust and ZT versions of Big Love. However, further restrictions were added for Ultra, Hyper, Klein, Zia and Zuna versions (no merging, no redistribution). The "Share merges" condition below the license on the right hand side was only deactivated because of the restricted versions. Merging is still allowed for the open versions.
