There is a single blue INPUT box near the left:</p><p>1 = text to image. Type a prompt, press Run.</p><p>2 = image to image. Load your own picture, press Run.</p><div data-youtube-video><iframe width="640" height="480" allowfullscreen="true" autoplay="false" disablekbcontrols="false" enableiframeapi="false" endtime="0" ivloadpolicy="0" loop="false" modestbranding="false" origin playlist src="https://www.youtube.com/embed/rst_h25FAXM" start="0"></iframe></div><p>Two samplers sit behind that box with the denoise already correct for whichever you pick, so there</p><p>is one knob and not two. The half you did not choose never runs — nothing to mute, nothing wasted.</p><p></p><p>At CFG 1 the negative prompt does nothing at all. Not a little — nothing. That is what CFG 1 means, and it is why the box is left empty in this file. If you want a negative prompt to work, take the Extended file instead.</p><h3 id="what-it-runs-on"><strong>WHAT IT RUNS ON</strong></h3><p>Our own Krea 2 build, and it is free — every build on that page opens for any signed-in member, no code and no card. You also need the Krea 2 text encoder and VAE from the official Comfy-Org</p><p>repository, and the ComfyUI Impact Pack from ComfyUI Manager (that is the switch, and it is the only extra thing this file needs).</p><h3 id="watch-the-vae:"><strong>Watch the VAE:</strong></h3><p>it is qwen_image_vae, NOT wan_2.1_vae. Use the wrong one and nothing warns you — no</p><p>error, no red border. It runs every step, decodes, saves a picture, and the picture is coloured</p><p>static.</p><h3 id="there-are-three-of-these-workflows"><strong>THERE ARE THREE OF THESE WORKFLOWS</strong></h3><p><strong>Turbo</strong></p><p>(8 steps, CFG 1, ~6s, no negative prompt),</p><p><strong>Extended</strong></p><p>(16 steps, CFG 2, ~22s, negative works),</p><p><strong>Base</strong></p><p>(20 steps, CFG 3, ~46s, negative works).</p><p>They are genuinely different files, not three presets of one. Start with Turbo if you just want to see something.</p><h3 id="everything"><strong>Everything</strong></h3><p>Links to all three files, the model, the folder each file goes in, and the settings: <a target="_blank" rel="ugc" href="https://forgebun.com/go/civit_krea2_workflows">grab it here</a></p><h3 id="the-model-on-its-own:"><strong>The model on its own:</strong></h3><p><a target="_blank" rel="ugc" href="https://forgebun.com/go/pro_models">Is here</a></p><p>Workflow, settings and write-up are mine.
