krea2 / comfy / turbo / createImage

This is the fast lane of the Krea 2 comfy nodes. krea2 / comfy / turbo / createImage runs the same 12B Krea 2 model as the base node, but with the turbo defaults you'd expect: 8 steps at cfg 1.0. The base variant wants 20 steps at cfg 4. The turbo variant wants you to not be precious. One prompt, a few seconds of cloud time, and you've got a Krea 2 image back as an IMAGE tensor - billed in Buzz instead of running on your GPU.

The turbo framing matters for what you use it for. Nobody reaches for an 8-step turbo pass for a final render; you reach for it to iterate fast, to try ten compositions without burning a wallet, and then take the winner over to the base node for the real pass. Krea 2's community moment was about the base checkpoint - a genuinely undistilled transformer at a time when everyone else shipped distilled - so this node is best read as the sketchbook companion to its 20-step sibling.

The inputs that matter

prompt is required; everything else has a sensible default.

• steps (8) / cfg_scale (1) - the turbo defaults. Resist the urge to crank cfg; distilled/turbo models get harsh and doubled fast above ~1.5–2.
• sampler / scheduler - same full ComfyUI menus as the base node. Leave empty for the platform pick.
• width / height - 1024×1024 default, up to 2048. Turbo at 2048 is where the "fast" pitch starts to sag; it's not a miracle worker.
• quantity - up to 12 in one job. This is the turbo node's superpower: 12 cheap drafts in a single billed call.
• diffusion_model / loras - CIVITAI_AIR / CIVITAI_LORAS sockets, wired from the Civitai Model/LoRA Selector nodes.
• negative_prompt, seed, output_format, image_metadata - standard.

Outputs are the pack standard: images (IMAGE), errors, workflow_id, raw_json, with the job's id and cost shown on the node.

Install and auth

Same as every node in this pack - one install covers all ~160. ComfyUI Manager → search Civitai Comfy Nodes → install, or:

cd ComfyUI/custom_nodes
git clone https://github.com/civitai/civitai-comfy-nodes.git
pip install -r civitai-comfy-nodes/requirements.txt

Then authenticate: export CIVITAI_API_TOKEN=..., a Civitai Auth node, or the Civitai sidebar sign-in. You need an account with Buzz - the whole pack bills per call.

The takeaway

If you're choosing between the Krea 2 nodes, think of it as base = finals, turbo = drafts, fal = the API-shaped variant with style references and a creativity slider. Turbo is the one you'd wire into a search loop or a batch-exploration workflow - the only Krea node where 12 outputs in one call actually feels like a bargain. Just don't be surprised when an 8-step image looks like an 8-step image.
