    Big Love Klein3 is also offered for $10 on Tensor Art. You can get Big Love Eryn1, Ultra5, Photo6, Zuna1 or Zia1 for $5.50 and Gwen1 or Hyper1 for $10 on Fanvue. Click 'Follow', buy a post, check your Fanvue DMs! A subscription includes the latest release and new ones within 30 days. Any problem? Contact me via chat.

    To create up to 85 free images per day in highest quality you can use Big Love here. For discussing photorealistic image generation join me on Discord.

    Big Love Klein is a fine-tune of Flux 2 klein. It can do txt2img and also edit images with prompts. It only needs 4 steps, so is quite fast. Check the "About this version" box on the right for info on the individual variants. Some are up to 3x faster.
    It is recommended to use it with ComfyUI. Put the downloaded model into the diffusion models sub folder of ComfyUI. 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.
    Settings are 4 steps (2 steps for upscaling), cfg1, Euler sampler, Beta scheduler, 832x1216, 1024x1536, 1280x1920 or 1536x2240 pixels

    Big Love Gwen is a finetune of Qwen Edit 2511 and can do NSFW image editing. It produces more realistic and sharp images with better skin texture & genitals than other Qwen checkpoints/loras. Txt2img is less reliable, but generates nice results too.
    Big Love Gwen1 allows commercial usage without additional fees (if no auto-generation involved) unlike Big Love Klein. With its better anatomy it is easier to get good editing results. As fast at 6 steps as Klein at 4 steps. Check the "About this version" box on the right for info on the individual variants.
    It is recommended to use ComfyUI. The Gwen1 workflows offer a skin enhance feature that is not available in Forge Neo. Move the Gwen1 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 qwen_image_vae.safetensors into the vae sub folder.
    For training a lora read here for Gwen1.
    Settings are 6 steps (3 steps for upscaling), cfg1, Euler sampler, Beta scheduler, 832x1216 or 1024x1536 pixels.

    Big Love Eryn is a fine-tune of Ernie-Image(-Turbo). You can run it locally with ComfyUI and Forge Neo. The fp8 version works with 8 & 12 GB VRAM. Use the (pruned) bf16 version if you have 16 GB VRAM or more. The "Full" versions are only meant for training a lora (coming soon!). Put the downloaded model into the diffusion models sub folder of ComfyUI or the StableDiffusion sub folder of Forge Neo. You additionally need to place ministral-3-3b.safetensors in the text_encoder sub folder and flux2-vae.safetensors in the VAE sub folder.
    Settings are 4-6 steps (3-4 steps for upscaling), cfg1, Euler sampler, Beta scheduler, 832x1216 or 1024x1536 pixels.

    Big Love Hyper supports generating at image sizes of 1664x2232 (4 megapixel) and higher with SDXL. Can be easily upscaled to 9 megapixel unlike the normal low-res images. Hyper currently has not fully stable anatomy, so needs more runs. Some prompts work better than others. It produces highly detailed and life-like images close to real photos. It has a special quality that cannot be achieved by just upscaling. The Hyper versions of Big Love are pay-only and special license conditions apply (see below).
    Settings are DMD2 lora with strength 1.0, LCM Exponential, 8 steps, cfg 1, clip skip 2, 1664x2432 or 1536x2240. Upscale with img2img with DMD2 lora with strength 1.0, same prompt, LCM Exponential, 1.25-1.5x, 4-8 steps, cfg 1, 0.3-0.5 denoise, clip skip 2.

    Big Love ZT, Zia or Zuna are fine-tunes of Z-Image(-Turbo) on the Big Love dataset. You can run it locally with ComfyUI and Forge Neo. The fp8 version works faster with 8 GB VRAM but produces more noise so may sometimes look more realistic, but details are not as good. Use the (pruned) bf16 version if you have 12 GB VRAM or more. The "Full" version is only meant for training a lora. Put the downloaded model into the diffusion models sub folder of ComfyUI or the StableDiffusion sub folder of Forge Neo. To make Big Love ZT/Zia/Zuna work you additionally need to place qwen3_4b.safetensors in the text_encoder sub folder and ae.saftendors in the VAE sub folder.
    Settings are 8 steps, cfg1, Euler or DPM++ 2s a RF sampler, Normal or Simple or Beta scheduler, 832x1216, 1024x1536 or 1280x1920 pixels. For upscaling 8 steps, cfg1, Euler sampler, Normal or Simple or Beta scheduler, 1.5x upscale.

    Big Love Ultra supports generating at image sizes of 1280x1870, 1360x1984 and higher. Can be easily upscaled to 6 megapixel unlike the normal low-res images. More photorealistic and detailed. A special quality that cannot be achieved by just upscaling. Ultra produces more details & sharpness when upscaling and detailing low-res images. The Ultra versions of Big Love are pay-only and special license conditions apply. See below.
    Settings are DMD2 lora with strength 1.0, LCM Exponential, 8 steps, cfg 1, clip skip 2, 1280x1864 or 1360x1984. Upscale with img2img with DMD2 lora with strength 1.0, same prompt, LCM Exponential, 1.25-1.5x, 4-8 steps, cfg 1, lora strength 1.0, 0.3-0.5 denoise, clip skip 2.

    Big Love Photo and Insta1 are finetuned versions of XL. Lust1 is a finetuned version of Lustify merged with Photo. They were trained on thousands of images and dozens of new concepts. Why they are the most realistic and versatile. For more details and prompting Photo1 read this article.
    Settings are DMD2 lora with strength 1.0, LCM Exponential, 8 steps, cfg 1, clip skip 2, 832x1216 or 1024x1496. Upscale with img2img with DMD2 lora, same prompt, LCM Exponential, 1.25-1.5, 4-8 steps, cfg 1, lora strength 1.0, 0.3-0.5 denoise, clip skip 2.

    Big Love XL is a combination of 5 different training branches of SDXL: original SDXL, bigASP, NatVis, Anteros and Pony. With a bit of Pony in it, some Pony loras (poses, characters) work too. It outputs a more photorealistic & creative look than the Pony versions and can also do paintings & cartoon.
    Settings are DMD2 lora with strength 1.0, LCM Exponential, 8 steps, cfg 1-1.5, clip skip 2, 832x1216 or 1024x1496. Upscale with img2img with DMD2 lora, same prompt, LCM Exponential, 1.5-2x, 8-12 steps (XL1/XL2), 4-8 steps (XL2.5-XL4), cfg 1, lora strength 1.0, 0.3-0.5 denoise, clip skip 2.

    Big Love Pony produces different images than both Pony & SDXL-based models. Pony tags are understood, but interpreted a bit differently. Some images lean more in the one or other direction depending on the prompt. It works with Pony loras as well as normal SDXL ones. It can turn anime/cartoon into photorealistic images in img2img. Pony3 includes a bit of Illustrious.
    Settings are DMD2 lora with strength 1.0, LCM Exponential, 8 steps, cfg 1-1.5, clip skip 2, 832x1216 or 1024x1496. Upscale with img2img with DMD2 lora, same prompt, LCM Exponential, 1.5-2x, 8-12 steps, cfg 1, lora strength 1.0, 0.3-0.5 denoise, clip skip 2.

    Training a (character) lora
    My advice is this: Take 10-30 high quality images (at least 50-100 for styles or poses), download OneTrainer, click the SDXL lora preset, choose Big Love as the base checkpoint, add your images as a concept, add tags on the Tools tab, and start training. If you train on Big Love Ultra change the training resolution to 1536 and provide 1248x1832 images.
    You will only get the full Big Love quality by training on real photos or extremely photorealistic images, which is usually not the case with a fictional character. It is all about image quality and not choosing boring images. Don't add posing images to a character lora, because Big Love provides the posing later for it. Focus mainly on good portraits with a few upper and full body images. Rather fewer higher quality images than a lot of average images. Read here for traing a lora on Big Love ZT2, ZT3, Zia1, Zuna1 or Eryn1.

    Fixing Anatomy
    If you want to keep the seed and repair anatomical problems in an image, activate the Extra checkbox in A1111/Forge and set Variation Strength to 0.01 to 0.1. Then generate until anatomy is fine. In Comfy there are sampler nodes that support variation seed (e.g. Inspire Pack), which do the same thing. Also possible to change steps or add commas to the prompt, but I do not recommend it. Extra/Variation Seed is more powerful and convenient as it gives you endless variations with just one click. There is always a variation which looks similar or even better with great anatomy.
    You don't need negative prompts for this. They are rather ineffective. You can also change the positive prompt to suppress things. Anatomy problems are also created by the prompt if you prompt contradicting poses that the model cannot combine. Better to fix the prompt first then.

    Reducing Saturation, Warm Colors and Sharpness
    These SDXL loras reduces the saturation and change the color temperature without reducing image quality. The lora strength defines the effect. Negative values increase saturation or add more warmth. To make an image softer use a lower strength for the DMD2 lora, e.g. 0.95, 0.9, 0.85.

    Big Love Hyper/Ultra/Photo Sizes

    Big Love Hyper supports these image sizes:
    1664x2432 (recommend)
    1536x2240
    Big Love Ultra supports these image sizes:
    1360x1984
    1280x1872 (recommend)
    Big Love Photo supports these image sizes:
    1024x1496 (recommend)
    832x1216
    You can also use the 16:9 or 2:3 versions of these image sizes as well as landscape orientation, but the above should be more reliable.
    The higher the image size, the lower the probability of good results. If you get too many problems with a higher image size, switch to the lower one. Some prompts do higher sizes fine, some do not. Do not use a lower image size than the recommended one, otherwise image quality will be lower. With higher image sizes anatomy problems occur too often.
    Remove fill words and unusual tags in the prompt. They can cause a quality reduction with Big Love Ultra/Hyper as they were not trained. Shorter prompts should work better as it is less likely that bad or untrained tags are in it.

    SFW Output - No Tits Please
    "Is there a trick so that Big Love doesn't always generate raised shirts or visible breasts?" I get this asked so often, while it is so obvious. Big Love knows what men want so it gives it to them. Negatives don't work that well for it. So you got to speak to it in the positive prompt like you were taking to a nun. "Breasts? How dare you speak such an obscene word to me." Don't mention breasts or any of these sexy parts. Instead describe clothes a lot. Don't write down your impure thoughts. God forbid! Yeah, I know, so hard. Describe her body shape, which also implies certain tits underneath the clothes.

    XL Prompting Advice
    SDXL prompts & prompts from various SDXL checkpoints work with it. Pony prompts too, but they create a more photorealistic look. Natural language prompts tend to create artistic glamour images with less skin detail while normal tags do more photo-style images. Big Love XL gives individual words more attention, so you don't need to rework prompts like Big Love Pony requires sometimes.
    XL1/XL2 has a tendancy towards cuteness and bright skin. If you get too much of it, remove words like cute, sweet, pale/fair skin & flash from the prompt. It also creates realistical analog photos with reduced image quality. Sometimes better to remove terms like analog or grain to increase quality. Decrease cfg to get a more natural look.
    XL2.5 can sometimes get too sharp. Reduce cfg or use less steps in img2img to make images softer.

    Pony Prompting Advice
    Pony prompts & prompts from other checkpoints work with it. Score tags and fill words like masterpiece or perfect skin have as good as no effect usually. A negative prompt is often unnecessary unless you want to make something vanish or avoid underage, but it can also change the style of the image.
    Pure booru tags and some other samplers may produce Pony style. Photographic terms or a simple prompts ensure a photo look. Sometimes it refuses to produce medium shots, portraits or close-ups unless you weigh the term heavily or remove feet, shoes, high heels, boots etc. from the prompt. wavy hair sometimes does not look so great.
    If it refuses to do porn, try simplifying the prompt. If you want to do a portrait, don't describe surroundings too much. If you want to do porn, describe the action mainly and don't focus on the people or surroundings in the prompt. The largest part of the prompt should be about the main subject of the image.
    If a prompt does not produce the intended image, you often only need to modify it a bit to make it work perfectly.

    Using Character Loras
    Big Love Pony supports Pony characters, but they look like real humans. There were some complaints about them not working, but the problem was not the model itself so far. So here are some tips:
    * Try Pony as well as SDXL character loras
    * Use a lora weight up to 1.5 if it does not reduce quality
    * If it is a well known character, add the name in the prompt and also give it a higher weight if necessary.
    * Check your negative prompt for problems. Delete it if necessary and rewrite it from scratch.
    * Render a lot of images to be able to pick those with the best resemblance.

    More SDXL Photorealism:
    You can highly improve the images generated with this model by using img2img, upscaling, detailing etc. The SDXL Lightning lora enhances the look and constrast despite only 8 steps. Alternatively, the SDXL DMD2 lora produces a sharp, but more natural look with less contrast. Also check out the Subtle Style loras, which nicely enhance images.

    Big Love License

    Big Love SDXL versions are licensed under CreativeML Open RAIL++M, the Big Love Z-Image, Ernie & Qwen 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
    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 and Gwen 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.

    Many thanks to the creators of SDXL, Z, Qwen, Flux klein, Pony, bigAsp and Lustify for making their wonderful models available. Big thanks to RaymondLuxuryYacht for allowing me to train on his fabulous images.

    Description

    Please note: The Klein versions of Big Love are pay-only and special license conditions apply. See description!

    Big Love Klein2 is better at NSFW image editing. Less tries needed. Anatomy improved, even in txt2img (but still far from perfect). Klein2 is more photorealistic & the harsh bright lighting was fixed. Various NSFW editing concepts that keep character consistency were trained.

    Download the GGUF version (Pruned nf4) with 8 GB VRAM, fp8 with 12-16 GB VRAM and bf16 with 24+ GB VRAM. nvfp4 version (Full nf4) for 2-4x faster rendering with Nvdia 5xxx gpus. Base version (Full bf16) for training loras. 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.

    Use ComfyUI with the workflows from the showcase images. Forge Neo produces too low quality.

    Hey I just bought your Klein checkpoint and am using your workflow. However, the inspire node is giving me the following errors:

    "Failed to convert an input value to a FLOAT value variation_strength, increment, could not convert string to float: 'increment'"


    "Failed to convert an input value to a INT value internal_seed, linear, invalid literal for int() with base 10: 'linear'"

    "Value not in list variation_method: '0' not in ['linear', 'slerp']"


    Could you please help me to resolve this? <3

    Google AI says: "Here is how to fix those specific errors:

    1. The "String to Float" & "Value not in list" Errors

    These errors happen because the node is trying to read a label (like "increment" or "linear") as a numerical value, or it's seeing a "0" where it expects a word.

    The Fix: Right-click the Inspire Sample node and select "Recreate Node" (if available) or simply delete and re-add a fresh version of the node.

    Manual Check: Ensure the variation_method dropdown is explicitly set to linear or slerp. If it looks like it’s already set correctly but still giving an error, toggle it to the other option and then back again to "reset" the underlying value.

    2. The internal_seed Error

    The node is seeing the word "linear" inside a box meant for a Seed (INT). This usually happens if the inputs got shifted or "wired" incorrectly in the backend of the .json file.

    The Fix: Check if you have any external Inputs (the circles on the left side of the node) connected to variation_strength or seed.

    Action: Disconnect any pipes leading into those specific slots, right-click the node, select "Convert [Input Name] to Widget," and then re-type the numbers manually.

    3. Quick Global Fix

    If the above doesn't work, your Inspire Pack might be out of sync with your ComfyUI version:

    Open the ComfyUI Manager.

    Click "Update All."

    Restart ComfyUI completely (close the terminal window and reopen). "

    @H4rryM3ss Zia has a slightly different look. Generates some things like nipples & genitals differently and also does some concepts better. Comes close to my vision of how Z should be. Have to see how ZT & Zia will develop im future. No clear plan yet.

    Actually I want experiment with a 3rd Big Love version of Z, but based on Z base. Have to see if it will be worth releasing.

    Absolutely fantastic v2 of Big Love Klein. Does many more NSFW things easier, with better accuracy.

    Any advice on how to prompt breast size without having the checkpoint make the breasts bare? I often will want to enhance the bust of the subject, while keeping the clothing intact.

    If you want to use a second image (actually up to 8 images are possible), you have to activate the switch. Then refer to image 1 and image 2 in the prompt and tell it what to do with each image. See the Klein1 showcase for examples.

    @user081525 Needs replicating some nodes in the Sampling box of my workflow. But would slow down the rendering if you only use only 1 or 2 images. Maybe someone posted such a workflow. Try googling or ask an AI.

    Well, got also sold on Klein2 for the image editing and got it via Ko-fi subscription. Great work. Got it to run in the Mac Comfy App. My Mac is not that slow but an Klein2 edit will take some minutes. Any chance to get a quicker preview by altering something in the workflow?

    In the ImageScaleToTotalPixels node(s) set the megapixels value lower for faster results. But it will look a bit different than the higher resolution end result.

    BIG Love Klein 2. is the best realistic model after Chroma. ! this thing is too powerful

    chrisss1Mar 28, 2026

    Still all of them pretty much suck at NSFW. SDXL seems to be the best for it. I can get and even better NSFW results with big love sdxl or lustify, not to mention sdxl is performance friendly and easier on my card.

    @chrisss1 SDXL: Best at skin texture & genitals. Z: Best at anatomy & composition. Klein: Best at image editing. They complement each other.

    Is there fp32 version for ZT3?

    Also seems like for Zia both 16 and 32 have same file size, at least that's what site shows.

    Yep, there is no fp32. Just using Civitai's limited naming scheme for more distinctice names. If you want to train on ZT3, read here.

    Flux.2 Klein 9B Is there a GGUF 8Q version available instead of the Pruned Model nf4 (6.04 GB)?

    SubtleShader
    Author
    Mar 28, 2026

    That is GGUF. It even says GGUF there. Look closer. Civitai just does not allow me to name it correctly.

    sarnara2Mar 30, 2026

    @SubtleShader My point is that I am aware it is in GGUF format. However, since NF4 is an extremely aggressive 4-bit quantization with significant loss, as I mentioned, I am specifically requesting “8Q” instead of NF4...... 8Q is that it significantly reduces VRAM usage while maintaining very low loss.

    @sarnara2 Civitai only lets me name it "nf4". Totally silly. Ignore that it says nf4!
    Sorry, I only offer Q5_K_M. It is not that much different from Q8. If you can run Q8 you should also be able to to run fp8.
    Please have mercy with me! I don't want to upload several additional GGUF checkpoints.

    The full bf16 or full fp32 download is always the training version for Z and klein.

    Any advise on using the full version with ai-toolkit? It only supports diffusers format, not safetensors files

    @xcession Please always mention if you mean Z or klein. Saves me writing about all possible cases. For Z you need Diffusers format, for Klein a safetensors file works with AI-Toolkit.

    So how is Flux.2 Klein 9b censored vs something like z-image-turbo? Do fine tunes and LoRAs make it more unrestricted?

    SubtleShader
    Author
    Mar 28, 2026· 1 reaction

    The original versions of both were not trained on NSFW images (or few only). So they just lack the knowledge. Of course, training NSFW concepts makes them reproduce them. The Big Love versions of Z and Klein are just as uncensored as the SDXL versions (check out the showcase images & galleries here). Just that SDXL has a lot more NSFW training after 2.75 years than Klein and Z, which are much younger.

    olternautMar 28, 2026· 1 reaction

    @SubtleShader So I've been learning to produce renders with z-image-turbo and base and getting used to LoRAs for them. Every so often I get weird results though. Now, I want to see how Flux.2 Klein 9B fine tunes perform. I hear from Gemini and Chatgpt that generally 9B is better at creating humans. I guess we'll see. Looking forward to when your 9B fine tune becomes available.

    @olternaut Actually Z has the best anatomy and composition. SDXL the best skin texture and genitals. Klein is great at editing.

    @SubtleShader Still going to test your 9B BigLove when it comes out. What do you mean better at editing? Do you mean prompting that it uses more natural language? I wish there was a super model that combines the best of everything.

    @olternaut Big Love Klein is pay-only. Maybe I will make Klein1 free in a few months or so. Have to see. With editing I mean that you give it one or more images and a prompt that tells it how to change the image or how to combine them. See the images with text overlays in the Klein galleries above.

    olternautMar 29, 2026· 3 reactions

    Not liking the initial results with 9B. Not your fault. I think it's the model itself. So I'm going to let the community work on that for a few months. I love your BigLove z-image-turbo models 1,2 and 3 though. But don't forget to give z-image-base some love too. Thanks.

    Info

    The Create option for Klein2 only lets you generate images with the the original Flux 2 klein and not Big Love Klein2. Previously it did not work at all. Sorry, I have no influence on this. Complain to Civitai or use TensorArt/TensorHub.

    Hi,

    Thank you for sharing.

    Which model should be used to train character LoRa for BigLove (Klein)?

    SubtleShader

    Mar 29, 2026

    Full Model bf16 (16.91 GB)

    bien622Mar 29, 2026

    OK. do you think LoRas trained with Flux.2 Klein base will also work with BigLove models?

    SubtleShader
    Author
    Mar 29, 2026

    @bien622 Yep, should work. Klein seems to be more robust in this regard than Z.

    bien622Mar 31, 2026

    I confirm that character LoRas trained with Flux.2 Klein base 9b work fine with BigLove Klein2. Could you point out why am i getting blurry, distorted, deformed images while using the your example workflows with BigLove bf16 version? When using the purned version the images are good even at 4 steps (no LoRa,, doesnt metter if i use qwen_3_8b_fp4mixed.safetensors or qwen_3_8b.safetensors text encoder),

    @bien622 Thanks for confirming. Sounds like you use the base version (Full bf16). It is meant for training and requires 20-30 steps and cfg 5 to produce normal images, which are still softer.

    elenazuclairApr 1, 2026

    @bien622 hi, I'm going to train a flux klein lora to test on big love also. Can you share which toolkit you used to train(I often use ostris AI Toolkit) and the parameters that worked for you?

    @elenazuclair I'm training Z and klein with AI-Toolkit and SDXL with OneTrainer. I do 35-60 epochs for finetuning and 70-100 epochs for loras. I use AdamW 8bit or Adafactor. I explained how to calculate steps & learning rate in this comment. Applies to klein too.

    Sorry, I'm not sure what you mean. I have to guess because various people had the same misconception. You tried Photo4 in img2img and expected it to edit the image? Photo4 or SDXL cannot do image editing. Img2img only "paints" over existing pixels which is nice for upscaling, improving skin or turning anime into photorealism. For image editing you need to use Qwen or Klein.

    I probably added the wrong seed. The next seed higher might be the right one. In general, anatomy is not perfect yet. Still more training needed for NSFW. Just try more seeds. If that does not work, try modifying the prompt.
