Big Love Cat is a finetune of LongCat and allows image editing. It reproduces faces extremely well with almost every image, so a lot more reliable than Klein & Gwen. It is only 6B and needs 8 steps cfg 1. Same Apache 2.0 license and text encoder as Qwen Image but 8 GB VRAM are enough. Txt2img is still experimental. The base model was only trained on one input image & only picks up random details from a 2nd image.

The bf16 version of Cat is faster than Klein & Gwen. The mxfp8 version is 1.6x faster than bf16 and just as fast as Gwen.

Training speed is more than 2x faster than any transformer model that I know. For training a lora you need SimpleTuner, which requires WSL under Windows and has a WebUI similar to AI-Toolkit. 2 scripts for installing WSL and setting up SimpleTuner are provided.

Big Love Cat produces the sharpest images with er_sde/Normal. In a few cases this adds subtle color grain which can be avoided by increasing steps to 12. er_sde/beta and Euler produce softer images without grain.

It is recommended to use ComfyUI. Move the model file into the diffusion_model sub folder of the models folder of ComfyUI, qwen_2.5_vl_7b_fp8_scaled.safetensors into the text_encoder sub folder and ae.safetensors into the VAE sub folder.

Settings are 8-12 steps (4 steps for upscaling), cfg 1, er_sde/Normal sampler/scheduler (Soft: Euler/Beta or er_sde/Beta), 832x1216, 1024x1536 or 1232x1824 pixels. Drag'n'drop showcase images into ComfyUI for a workflow.

Big Love License

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

For clarity, the following version tiers are defined:

Restricted versions: Ultra, Hyper, Klein, Zia, Zuna, Eryn, Gwen, Cat

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, restrictions were added for Ultra, Hyper, Klein, Zia, Zuna, Eryn, Gwen and Cat 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.
