Krealism 📷
A realism finetune of Krea 2 Turbo, built for ComfyUI. Film look, natural color, candid framing. No LoRAs needed.
✋ Which file do I grab?
V3.1 (latest):
| File | Size | Quality (vs bf16) | Speed (RTX 5090, 1 MP) | Pick it if |
|---|---|---|---|---|
| Krealism_V3.1_bf16.safetensors | 26.3 GB | the original | 0.59 s/step | you have 32 GB of VRAM and want the reference |
| Krealism_V3.1_int8_convrot.safetensors | 14.1 GB | 0.007: nearly identical | 0.30 s/step | 💡 most people. bf16 quality at half the size |
| Krealism_V3.1_mxfp8.safetensors 🆕 | 14.5 GB | 0.019: very close | 0.33 s/step | RTX 50 series. fp8 quality, faster |
| Krealism_V3.1_w4a8.safetensors 🆕 | 8.8 GB | 0.031: close | 0.33 s/step | smaller cards. nvfp4 size, better than nvfp4 |
| Krealism_V3.1_nvfp4.safetensors | 8.8 GB | 0.059: same person, details change | 0.26 s/step | the fastest file (RTX 50 series runs nvfp4 natively) |
| Krealism_V3.1_fp8.safetensors 🔧 | 14.1 GB | 0.016: very close | 0.46 s/step | your setup runs fp8 but not int8 or mxfp8 |
How to read the quality score:
- LPIPS vs the bf16, one step from the same starting point, averaged over 3 prompts at 3 points of an 8 step render.
- 0 = identical. Under 0.01 you can't tell them apart, 0.01 - 0.03 is very close, 0.03 - 0.06 small details change, above 0.06 you can see it.
The two new files:
- mxfp8: 8-bit with a scale for every 32 values instead of one per layer. Fast on RTX 50 series; older cards load it, but get no speed gain.
- w4a8: 4-bit weights, 8-bit math. Half the size of the 8-bit files, and on an RTX 5090 just as fast as them. Fast on RTX 30 series and newer.
- ⚠️ Both need an up-to-date ComfyUI (with Comfy Kitchen). Older installs won't load them.
- On an 8 GB RTX 5060 laptop, both run about as fast as int8 (2.6 - 2.8 s/step at 1 MP) and twice as fast as bf16 (5.8 s/step).
V1.0 (older): Krealism_V1.0 (bf16), V1.0-fp8, V1.0_int8_convrot and krealism_v10Turbo-q8_0.gguf are still here if your workflows depend on them.
📂 All of them go in:

└── diffusion_models/
Settings
The same ones ComfyUI's Krea 2 template uses. Nothing fancy:
- Steps: 10
- cfg: 1.0
- Sampler: Euler
- Scheduler: Simple
- VAE: qwen_image_vae
- No shift node, no LoRAs
