Big Love Klein is a fine-tune of Flux 2 klein. It can do txt2img but also edit images with prompts. Txt2img is currently experimental and requires more prompt & seed hunting. Image editing works stable. It only needs 4 steps, so is quite fast (5 sec on 5090, 15 sec on 5070). You can run it locally with ComfyUI and online on Tensor Art. Use the GGUF Version with 8 GB VRAM, the fp8 version with 12-16 GB VRAM and the bf16 version with 24+ GB VRAM. The base version (full fp32) is meant for training a lora only. You also need qwen_3_8b_fp8mixed.safetensors in the text_encoders sub folder (Qwen3-8B-Q5_K_M.gguf wth 8 GB VRAM) and flux2-vae.safetensors in the vae sub folder. Forge Neo is not recommended, because it currently produces too low image quality with Klein, which will hopefully change soon.

Big Love License

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

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 Tenor 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 the Ultra and Klein versions of Big Love, and you may not share merges or lora extractions that incorporate Ultra or Klein versions. You may merge all other versions of Big Love and share these merges.

6. When sharing allowed merges (non-Ultra, non-Klein versions) as well as finetunes, you must apply these same additional license terms.

7. Redistribution of Ultra and Klein versions of Big Love is prohibited. They may only be obtained from official sources designated by the creator.

8. All use-based restrictions from Attachment A of the CreativeML Open RAIL++M license apply to SDXL versions and their derivatives. All use-based restrictions from 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 non-Ultra and non-Klein versions of Big Love. However, further restrictions were added for Ultra and Klein versions (no merging, no redistribution). The "Share merges" condition below the license on the right hand side was only deactivated because of the Ultra and Klein versions. Merging is still allowed for the other versions.
