zhenzhen-image-gk-v15-lowprice

Comfly_zhenzhen_image_gk_v15_lowprice is the pack's GK V1.5 image node, and the author's own changelog gives you the whole story in one line: it "merges GK V1.5 text-to-image and image-edit models" into a single node. Generation and editing, one dropdown. It was part of the big July domestic-storefront drop that introduced the low-price family, and like the rest of that family it's cheap, cloud-run, and shares one settings node.

If you're comparing it to the G-2 node elsewhere in the pack: GK V1.5 is the older model line, and its personality here is "simple and cheap." The interface is minimal - model, prompt, size, count, one reference image - which makes it a good first stop for anyone who just wants an image without a wall of options.

How it works

Pick zhenzhen-image-gk-v15 for text-to-image or zhenzhen-image-gk-v15-edit for editing, write a prompt, and hit run. Outputs are image, image_url, task_id, and response.

The inputs you'll actually set:

• model - the t2i / edit switch.
• prompt - for edit mode, connect a reference to image1 and describe the change.
• size - 1:1 / 16:9 / 9:16 / 3:2 / 2:3. Five ratios, no adaptive, no custom - keep it simple.
• n - how many images, 1 to 10. Each one costs credits, so start at 1 and only dial up when you're batch-picking.

Installing and setting up

Install via ComfyUI Manager (search Comfyui-zhenzhen) or:

cd ComfyUI/custom_nodes
git clone https://github.com/T8mars/Comfyui-zhenzhen

Restart ComfyUI. No model downloads. Connect the Comfly Seedance2 Low Price Settings node's api_config output, or set SEEDANCE_API_KEY - the family's standard plumbing.

Troubleshooting

The same tripwire as every low-price node: no api_config connection means an immediate "empty api_key" error, and the settings node is the fix. On edit mode, the single image1 reference is the whole input - GK V1.5 edit is a one-image editor, so don't expect multi-reference composition here. And remember n multiplies cost: 10 images at once is ten times the credits, and if one of them fails you've spent on the batch. The skip_error toggle is available if you'd rather a failure return empty than stop the queue.

Reasonable take: this node isn't the most powerful in the image family, and it doesn't pretend to be. It's the "I need an image, I know the ratio, go" option. When you outgrow five ratios and one reference, the G V2 and NB nodes up the ladder are waiting.
