Two ways to run it, (Text to Image + Image to Image) chosen with one number. There is a single blue INPUT node near the left:

1 = text to image. Type a prompt, press Run.

2 = image to image. Load your own picture, press Run.

Two samplers sit behind that box with the denoise already correct for whichever you pick, so there

is one knob and not two. The half you did not choose never runs — nothing to mute, nothing wasted.

Twenty is the base number. We swept 20, 25 and 30 on a fixed seed: 30 looked better.

WHAT IT RUNS ON

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

repository, and the ComfyUI Impact Pack from ComfyUI Manager (that is the switch, and it is the only extra thing this file needs).

Watch the VAE: it is qwen_image_vae, NOT wan_2.1_vae. Use the wrong one and nothing warns you — no error, no red border. It runs every step, decodes, saves a picture, and the picture is coloured static.

THERE ARE THREE OF THESE

Turbo (8 steps, CFG 1, ~6s, no negative prompt),

Extended (16 steps, CFG 2, ~22s, negative works),

Base (30 steps, CFG 4, ~46s, negative works).

They are genuinely different files, not three

presets of one. Start with Turbo if you just want to see something.

Everything — all three files, the model, the folder each file goes in, and the settings:

The pro model on its own:

Workflow, settings and write-up are mine. Krea 2, its text encoder and VAE are Comfy-Org's. The

switch node is from the ComfyUI Impact Pack by ltdrdata.
