Krea 2 Promo

Krea 2 Base & Turbo — NVFP4 / FP8 / MXFP8 / INT8 / ConvRot INT8

Quantized versions of Krea 2 Base and Krea 2 Turbo, converted using silveroxides/convert_to_quant (ctq CLI) with ComfyUI-compatible metadata.

Which Model Should I Use?

Train on Raw, run on Turbo. LoRAs trained on the Raw base model transfer well to Turbo for inference. Raw is the undistilled base checkpoint — diverse, malleable, ideal for LoRA training and fine-tuning. Turbo is an 8-step distilled checkpoint built for fast, high-quality generation at 1k–2k resolution.

Important ComfyUI Update: INT8 Full Support

INT8 Native Support - very fast, works on any RTX 30xx, 40xx or 50xx graphics card ComfyUI supports the INT8 models via the "Diffusion Model loader" and the "Load Clip" text encoder nodes. Thus far, they only support regular INT8 models, not convrot INT8.

Recommended Inference Settings

Turbo — fast inference, high quality:

• Steps: 8
• CFG: 0.0 (disabled)
• Mu: 1.15
• Resolution: 1024–2048px

Raw — undistilled base model:

• Steps: 52
• CFG: 3.5
• Resolution: up to 1024px

Text Encoder

Krea 2 requires the Qwen3-VL 4B text encoder. Load it in ComfyUI's CLIPLoader with type set to krea2.

VAE

Krea 2 uses the same VAE as Anima:

Which Format Should I Use?

• RTX 30xx → INT8 ConvRot for best quality, INT8 for fastest
• RTX 40xx → FP8
• RTX 50xx Blackwell → NVFP4, MXFP8, or FP8, your choice

Conversion Details

All variants converted with:

• --simple (round-to-nearest, no learned rounding)
• --comfy_quant (ComfyUI-compatible layer names and metadata)
• --save-quant-metadata (quantization info embedded in file)
• --low-memory (reduced peak RAM usage during conversion)
• --flux2 profile

ConvRot variants additionally use Hadamard rotation (--convrot) prior to quantization to reduce outliers and improve accuracy.

Usage in ComfyUI

Load via the standard diffusion model loader node. Requires a ComfyUI build with comfy_quant support. Recommended nodes: Bob Johnson's Nodes
