https://civitai.com/models/3671?modelVersionId=1623867 Use e621 tags (no underscore), Artist tag very effective in YiffyMix. GridList Species(v60)/Artist(v61/v52) update!! & LoRAs (SDXL)/samples/wildcards Recommend Artist List for new user & comfyUI workflow YiffyMix doesn't need Pony score tags, Don't use SD1.5 vae in SDXL, you will get fried image. Example Setting Setting SDXL (SDXL-lightning & NoobXL) Steps = 12~24 Sampler = "DDPM", "Euler A SGMUniform", "Euler SGMUniform" CFG scale = 4 Negative embeddings SDXL = ac-neg1, ac-neg2 (You don't really need this) Postive LoRA SDXL = SeaArt Quality Tags LoRA (You don't really need this) Stop at CLIP layers = 2 LoRA Training imgs count = 15~50 total steps = epoch * imgs count * folder loop = 3000~4500 network_dim = 64 network_alpha = 128 (SDXL) \ 16 (Noob) learning_rate = 0.0002 unet_lr = 0.0001 text_encoder_lr = 0.00005 lr_scheduler = "cosine_with_restarts" mixed_precision = "bf16" optimizer_type = "Adafactor" optimizer_args = [ "scale_parameter=False", "relative_step=False", "warmup_init=False", ] YiffyMix v4x V-pred Setting # YiffyMix v4x A1111 SD-WebUI or Forge V-pred Setting 1.Download config file ".yaml" paste next to the model. 2.Raname ".yaml" same as model name. ( check the ".yaml" has [parameterization: "v"] line ) 3.Restart SD-WebUI ( if config fails to load, the model just generate noise ) # YiffyMix v4x ComfyUI or StableSwarmUI V-pred Setting Add node "ModelSamplingDiscrete", Sampling = "v_prediction" workflow demo # ComfyUI V-pred Setting (old version) 1.Copy config ".yaml" to [ComfyUI\models\configs] and refresh ComfyUI 2."Load Checkpoint (With Config)" [Right Click\AddNode\advanced\model_merging] workflow:[Load Checkpoint (With Config)]-[KSampler]-[VAE Decode]-[Save Image] # v-pred mode troubleshoot If you use new version webui-forge and failed detect v-pred model. Try update webui-forge (click update.bat). When loading v-pred model, you will see this line in cmd console: left over keys: dict_keys(['v_pred']) # v4.x some time will get little fried issue image in this case Use "Dynamic Prompts with __wildcards__ prompts" and "batch size > 1" Just generate again with same prompts with parament, it will return normal. Version Info v1.x [2D,512~768] old model, unstable, low resolution v2.x [2D,512~896] e621 dataset + 30~40% SD5 dataset v3.0 [2D,3D,512~1088] large dataset then v2.x version, can do 2D, 3D v3.1 [2D,3D,Real,512~1088] more realistic, but loss some concept (e621 tag count lower 1000) v3.2 [2D,3D,Real,512~1088] unstable version, use SNR version FluffyRock, more noise detail v3.3 [2D,3D,Real,512~1088] stable version, more detail, more sensitive to prompts v3.4 [2D,3D,Real,512~1088] ※include Fluffy Rock Quality Tags-LoRA stable version, more detail, clear result, reduce some noise (like bush,pattern) v3.5 [2D,3D,Real,512~1088] unstable version, contrast & detailed enhance v3.6 [2D,3D,Real,512~1088] stable version, more sensitive to e621 tags v3.7 [2D,3D,Realistic,res:512~1088,VAE Baked] stable version, reduce noise overactivity, fix blurry eyes and finger error, fix failed background depth v4.0 [2D,3D,Real,512~1088,VAE Baked] v-pred version, remix from EasyFluff accuracy anatomy and style with fewer prompt, little dim blue average color with smooth noise, weakly negative prompt issue v4.1 [2D,3D,Real,512~1088,VAE Baked] v-pred version, color and low contrast fix, reduced realistic noise. v4.2 [2D,3D,Real,512~1088,VAE Baked] v-pred version, more contrast and detail, yelow issue. if you feel too fried use Rescale CFG =0.35 v4.3 [2D,3D,Real,512~1088,VAE Baked] v-pred version, clear artist style, fix most yellow/brown issue the version doesn't need CFG Rescale v4.4 [2D,3D,Real,512~1088,VAE Baked] v-pred version, no more yellow/brown issue. the version doesn't need CFG Rescale v5.0 [2D,3D,Real,896~1536] SDXL-lightning version, base on Compassmix XL. v5.1 [2D,3D,Real,896~1536] SDXL-lightning version, more e621 dataset, lower human face, better NSFW stuff. v5.2 [2D,3D,Realistic,res:896~1536] SDXL-lightning version, increase average quality. Little unstable than v51 but more creative. v6.0 [2D,3D,res:896~1536] ※NoobXL eps version (not v-pred) More character better sex pose, limited and uncontrollable style (mostlly anime style). v6.1 [2D,3D,Realistic,res:896~1536] ※NoobXL eps version (not v-pred). More realistic detail, reduce anime style, fix flat and boring background. v6.1a-RE [2D,3D,Realistic,res:896~1536] ※NoobXL realistic enhanced (RE) version. Same as v61 but adjust average style to simi-realistic. Basic Style Negative Prompt SD1.5 unusual anatomy, mutilated, malformed, watermark, amputee, mosaic censorship, sketch, monochrome Negative Prompt SDXL malformed, worst quality, bad quality, signature, text, url 3D Artwork Style Prompt: blender \(software\), ray tracing, 3d, unreal engine Photorealistic Style Prompt: [:photorealistic, analog style, realistic, photorealism:0.5] Negative prompt: [:bwu:0.5] Recommend Refiner: IndigoFurryMix v110-Realistic Switch at 0.5 Prompt SDXL v5x: by Mandy Disher, by Wim Wenders, by Robert Rauschenberg, [by Fossa666::0.65], ultra realistic, photorealism, photograph, Prompt SDXL v6x-Noob: [3d \(artwork\):(ultra realistic, photorealism, photograph:1.35):0.35] Negative prompt SDXL: sketch, manga, vector, line art, toony Some SD tricks using a1111 [a:b:value] script prompt: 1.High details increase [:some style or artist:0.15] Let first 10%~20% steps free, then style will create on high detail base. 2.Avoid character pose affected by artist or background [:artist or background prompt:0.2] Skipping first 20% steps can avoid this. 3."A artist character" + "B artist style" [A artist:B artist:0.35] Most base concept is done in first 30%~50% steps, last steps only change style.
