Watch the full video first if you want to understand how this Krea2 merged-model implementation workflow works in practice. The video demonstrates a compact Krea2 image-generation route built around a pre-merged model file, combining model-side enhancement, conditioning rebalance, and a longer DDIM sampling setup for more controlled vertical image production.
This ComfyUI workflow is designed for Krea2 merged-model image generation. Unlike a standard Krea2 Turbo workflow that directly loads the original base model, this version loads merge50.safetensors as the main UNET model. That means the model fusion has already been prepared before running the workflow. The graph itself does not need to perform a live model merge every time. Instead, it uses the pre-merged model as the starting point, making the workflow simpler and more practical for repeated generation.
The model route loads merge50.safetensors through UNETLoader, then passes it into ComfyUI-Krea2T-Enhancer. The enhancer is enabled, with strength set to 1. This gives the workflow an additional model-side enhancement layer before sampling. The purpose is to make the merged Krea2 model respond with stronger texture, cleaner style behavior, and better visual presence.

The text encoder route uses qwen3vl_4b_fp8_scaled.safetensors with the Krea2 CLIP type. The VAE route uses qwen_image_vae.safetensors for final decoding. This keeps the workflow aligned with the normal Krea2 ecosystem while allowing the main model itself to come from a merged checkpoint.
The conditioning route uses ConditioningKrea2Rebalance with a custom 12-layer weight structure:
1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 2.5, 5.0, 1.1, 4.0, 1.0
The multiplier is set to 2.5, with renormalize disabled. This provides stronger prompt control than a plain conditioning route while avoiding the more extreme pressure of multiplier 4.0 setups. It is a balanced configuration for testing merged-model behavior, prompt response, color structure, composition, and stylized texture.
The sampling setup uses KSampler with 20 steps, CFG 1, DDIM sampler, sgm_uniform scheduler, fixed seed, and full denoise. Compared with the common 8-step Krea2 Turbo baseline, this version gives the workflow a slower but more deliberate render path. It is suitable when the creator wants more stability, stronger structure, and more consistent testing across multiple outputs.
The latent section uses FluxResolutionNode with a 1.4 megapixel target, 9:21 Ultra Tall aspect ratio, and divisible-by-64 alignment. The batch size is set to 4, making the workflow useful for generating multiple vertical image candidates in a single run. This is practical for RunningHub app previews, poster selection, thumbnail experiments, style tests, and prompt comparison.
The example prompt focuses on a highly stylized oriental fantasy scene: a woman in crimson ceremonial robes standing in a sacred hall, surrounded by huge ivory scrolls covered in calligraphy that spiral through the air like living ribbons. The scene emphasizes theatrical motion, painterly color contrast, traditional architecture, sacred performance, floating sparks, divine wind, and literary magic.

Suggested workflow:
Use this workflow when you want to test a pre-merged Krea2 model rather than repeatedly building a merge inside the graph. Start with a strong visual prompt and generate a batch of four candidates. Compare whether the merged model improves texture, color, style consistency, and composition compared with the base Krea2 Turbo model. Since the workflow uses 20 DDIM steps, it is better suited for deliberate testing than ultra-fast preview. Keep the prompt focused on one main visual direction, then adjust the merged model, Rebalance strength, or sampling settings only after the subject and composition are already stable.
