FAQ
Comments (90)
I will test it more but so far I seem to be getting better results with v1 than v2.
May be some different workflow or parameter. haha...😂🤝
I agree , absolutely love your model , but V1 is amazing , V2 is messing up my character loras , no matter what Wf i use . V1 is a beast.
@cristianlyon67811 Thanks a Lot! ❤️💐👍
@cristianlyon67811 same, i thought i have a problem with lora training but when i used v1 the character loras were great
You're shooting yourself in the foot by putting this under Flux.2 Klein 9B Refiner lol. That's bascially not searchable.
Haha... Thanks...
How do you use this model along side the main model flux2Klein9BTrue_v10Bf16 safetensor checkpoint? coz CFG guider or Ksampler can only handle one diffusion model. Is this lora?
Sorry! Pls don't use V2_bf16 safetensors file, due to network problem, pls download V2 from HF or Modelscope site under my repo. 🤝💐
@wikeeyang Ok bro thanks for suggestion. What do you think, is the image quality realism and prompt understanding better in flux2Klein9BTrue_v10Bf16 17GB or the Flux2-Klein-9B-True-v2-fp8mixed.safetensors 9gb model? Does higher file size means better?
@haidensd58757 Yes, if you have good GPU VRAM, high precision will better, but if your VRAM not so good like above 24GB, then fp8mixed will better, due to this is mixed precision, then it's quality compare with fp16 less then 3-5%, almost the same.
@wikeeyang Alright bro thanks for the clarity. but why is this current Flux2-Klein-9B-True v2 f16 checkpoint only 18MB? it should be 17gb insn't?
@haidensd58757 due to network, I can't upload v2-bf16.safetensors file to Civitai site successfully, but in civitai if not one safetensors weight can't publish version of model, then I just upload a tiny file not the true v2-bf16.safetensors for model version publish, understand? bro...🤣🤣🤣🤝, I commit pls download model weight file from HF or Modelscope site under my repo...
@wikeeyang Oh i got it and understand your struggle. yes HF link is the rescue. And thank you once again, really appreciate your hard work man. 🫡🏆
@haidensd58757 you are welcome, bro. 🤝✌️
Very impressive! I tested 9b fp8: Klein base / v1 / v2. v2 is my new main model.
Thanks a Lot! 👍💐❤️
I downloaded the BF16 quant of the V2 model from huggingface, but when I run it I get this error:
ERROR: Could not detect model type of: F:\AI Models\diffusion_models\Flux2\flux2Klein9BTrue_v20Bf16.safetensors
The original FLux.2 Klein 9B models by Black Forest Labs work perfectly fine. I'm using ComfyUI.
Haha...That's so strange! All model file had tested in ComfyUI newest version.
@wikeeyang This is strange because I've just downloaded V1 and it works fine. :/ I will try downloading V2 again. By the way, the model description says that the model is undistilled, but this is not the case. The model works properly only when CFG is set to 1.0 which means that this is a distilled model. Did you upload a wrong file by mistake? If not and this was intended, the description should be corrected.
@mmdd2543 De-Distilled of the models is my model feature.
The solution to this problem is to fully update your ComfyUI and all node plugins. Click Update All in the Manager.
Hello, i can't download the checkpoint, v2 bf16 is now 18MB, not 16GB
@hoyjooh170 Thanks a lot.
sorry for this absolutely noob comment, i didn't took time to read the whole post... but if it helps lazy folks like me, thank you @hoyjooh170
UP your model is absolutely amazing! Truly impressive — I'm really enjoying it.大佬您的模型太棒了!很赞,正在体验。
Tks a lot! your likes is my greatest motivation. 谢谢!大家喜欢,就是我继续调制和优化模型的最大动力。
The Flux series models, produced by Black Forest, are open-source but not for commercial use. have Flux.1 / Flux.2 / Flux.2-Klein etc, pls ref to https://huggingface.co/black-forest-labs, it's Pro and Ultra or Max model not open source.
V2到底是有没带加速?为什么我没加加速lora 4步或者25步都可以
Besides the model, what do I need to install? VAE, Text Encoder, etc.???
you need the Text Encoder and VAE part from Flux2-Klein-9B, you can get it from comfy-org repo, and pls ref to workflow which had provided under my repo.
Thanks for making it! It's an amazing model.
I have found CFG=2.0, Steps=16, Euler_Ancestral (or Euler), and 0.25xTurboLoRA to give excellent results at 4K (2048x2048).
The same settings at 1024x1024 and 4 Steps give a reasonable fast preview for draft-prompting.
It clearly outperforms the original F2K9B (Base or distilled) with or without Turbo LoRA. Also, it does actually compete with and even wins the competition against NanoBanana 1/2/Pro, Imagen 4, and GPT Image 1.5 in terms of realism and quality of generation. Only the world knowledge (limited by the text encoder and original model size) is behind these commercial models.
Much thanks for your recognition of the model, and also much thanks for sharing your valuable experience. Bro. 🤝💐✌️👍
大佬,能更新Q6_K和更小文件的GGUF版本吗?
A preview: Today my friend lrzjason's consistency LoRA, https://huggingface.co/lrzjason/Consistance_Edit_Lora/resolve/main/f2k_9B_lcs_consist_20260415.safetensors, will be released. When it combined with my V1 or V2 models, it can greatly improve the Klein model's drift and color bias issues in I2I.
I watched his personal test results, and there is a significant improvement compared to f2k_9B_lcs_consist_preview_20260328 version.
@wikeeyang Thanks but The file is not found, Can you update the link or tell us where the final version will be available ?
@hazzoom82659 Wait a bit, he is making a video now, and will upload the model later. 🤣🤣🤣
Can anyone help me by answering this?
This is the first Klein model I've tried, and it's more than incredible, especially version 2. I couldn't generate NSFW content beyond bare breasts, so I wanted to know if it's possible to do it with version 2 while maintaining the same quality?
Thank you so much for taking the time to work on this model and for sharing it! I've been doing lots of experiments using it in different workflows and it's simply incredible! 再谢了,朋友.
You're welcome and thanks a lot for your appreciation. Your liking is my greatest motivation. ✌️🤝❤️
bf16 v2 file is 19mb...
I comment don't use it, please download from https://huggingface.co/wikeeyang/Flux2-Klein-9B-True-V2
Amazing model, but I've noticed that V2 has less prompt and edit adherance compared to V1 (prompt can be fixed with high cfg and negative turbo lora), but edits like face swaps and keeping body shape from a reference is less consistent on V2
EDIT: Acutally V2 seems more realistic on the face swaps but you need custom nodes to control the weight of the latents
Thank you for your feedback and sharing, thank you again. Yes, there are some differences between V1 and V2.
This works great with turning anime, 3d images into realistic one, but my only issue is the faces. Turning cartoon looking images into realism usually outputs Asian faces even if I tell it to use European, English looking people with TextEncodeQwenImageEditPlusCustom.. Is there a way to get it to fix this?
Pls try my Flux2-Klein-9B-True-V1, V2 has made some optimizations for Asian faces.
Has the V2 model been censored? I need to add loras for nsfw images.
图生图会给比较糊的图添加细节,怎么设置可以减少呢?
一个是用提示词明确继续保持原图的模糊状态,不要高清;一个是用一些可以减少细节的 LoRA,比如 detail-slider 这一类,权重负值一般是减少细节。
@wikeeyang 好的,谢谢大佬
感谢大佬贡献这么棒的模型,有几个问题请教:请问是不是无论多少步,CFG都是1对吗?还有就是我发现文生图我一般是生成东亚女性,多次生成会出现脸部都是同一张脸的问题,是我哪里设置的不对吗?
cfg 建议是 1,但你也可以试着微调,比如 1.1,看看出图有啥变化,步数可以 15-30 步,反正没有一个太绝对的标准,只要输出的图自己满意即可,另外,V1 是老外脸,亚洲脸普遍比较丑;所以,V2 训练集做了一点优化,如果你想要老外脸,可以提示词里面写的比较详细明确即可。

Update All or download the new version of comfy
@wikeeyang thanks, worked
@GitarooMan thank you
(I'm a noob, sorry if I'm talking nonsense) I'm using the Flux2-Klein-9B-True-v2-mxfp8mixed.safetensors model for editing. I am also using the recommended workflow. I noticed that when making edits, it applies a filter to the person's skin, making the color warmer, or pinker even without LCS-Control. Is this from the model itself or is it some configuration that I can fix within the workflow? My current configuration is steps 15, cfg 1, euler
This is a normal issue with models. Currently, all models based on the Dit/VAE architecture basically have this problem. It is caused by the color propagation through the latent space and is very difficult to completely solve. For example, if you change the clothing in the original image to red, the resulting image will generally have a warm color tone, whereas if you change it to blue, it will have a cool color tone. You can make adjustments by stacking some control LoRA and post processing color correction nodes, but this only applies to a single scenario, and different tasks require parameters to be rematched.
@wikeeyang Ah, I see, thank you very much for the answer! I'm trying to generate an Instagram-style AI influencer, but realistic and with great quality, and I need to keep my character consistent. Which model would you recommend? The idea is to take the reference image of my model, take the reference from another photo, such as pose, expressions, and generate a new image of my model with the same environment, clothes and expressions as the second reference image.
@user220123 Currently, the only decent open-source option is Klien. You can add a consistency-enhancing LoRA, or use paid models, such as Google Banana Pro or GPT Image 2.
@wikeeyang Thank you very much!
I think only you can fix the extra limbs/legs/hands issue of Flux.2.Klein-9b. Please make it happen.
I'm trying now, it's pretty tough, hope V3 can reduce the chances of this happening. Thanks!
Have you considered publishing INT8-Convrot quants of your amazing model? Comfy made a big post about it last week - it's essentially obsoleting standard FP8
Yeah, please download it from my Huggingface Repo. Thanks!
@wikeeyang Thanks! On your HF model card it says "...Flux2-Klein-9B-True-V3-INT8-ConvRot.safetensors, it can load by ComfyUI-INT8-Fast." and "I had to quantized and uploaded the Int8 version of the model, which can be loaded directly with ComfyUI's official node, Flux2-Klein-9B-True-V3-int8mixedrow.safetensors"
However, int8-Convrot can now be loaded with native Comfy Core "Load Diffusion Model" node.
Is there any actual difference between those two model files, besides one is from one person, the other is from you (but are both still "same")?
@altoiddealer About True-V1 to V3, please download my "int8mixedrow" version, it is the same with int8convrot offical version of ComfyUI.
@wikeeyang Thanks - I downloaded the other one first and it did not load from Comfy node. Now I understand :D That other one includes the "fast" which I see indeed requires the custom node.
Amazing work man, thanks!
Is a Distilled version of the True models viable or does that defeat the purpose of the model?
you can add Turbo LoRA to try...
