zhenzhen-sd2-seedream-v5-pro-lowprice

ByteDance's Seedream V5 Pro is one of the most-used closed image models on the planet for one job in particular: making product photos look professional. Comfly_sd2_seedream_v5_pro_lowprice is the zhenzhen pack's node for it, pointed at the domestic low-price shop (api.seedance.nz, roughly 75% of the overseas rate per the README). It does text-to-image and image editing with up to ten reference images, and it's the node the README explicitly recommends for 电商出海 - e-commerce going overseas - because it supports a wider-audit mode with looser content filtering than the strict overseas endpoint.

The "sd2" prefix is just the pack's shorthand for the second shop (the 贞贞平价AI小屋 domestic site) - don't read anything into it. Like every low-price node here, it gets its credentials from an api_config dictionary, which you build with the pack's Comfly_seedance2_low_price_settings node.

How it works

Async task flow: upload your reference images, submit to the shop, poll until done, download, return a IMAGE tensor plus image_url, task_id, and response. Nothing runs locally except the node's own bookkeeping - the model is entirely server-side, so there's no VRAM bill.

The inputs that matter

• mode - text_to_image or image_edit. The second one is where the ten image1–image10 inputs come in.
• model_family - seedream-v5-pro (domestic) (default) or dola-seedream-5.0-pro (overseas). The overseas variant is the looser-audit one the README suggests for cross-border e-commerce.
• prompt - required. For editing, describe what changes and reference the images.
• resolution - 1k, 2k, or custom (then set width/height, which go 240–8192 in steps of 8).
• output_format - png or jpeg.
• image1–image10 - reference images for edit mode. Product shots, model-in-outfit, background swap - this is the meat of the node.

seed is cache-control only (not sent to the API), so no seed-faithful re-rolls; re-running with fixed seed reuses the cached result.

Installing it

ComfyUI Manager, search "Comfyui-zhenzhen", or:

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

restart, no model downloads. Wire a settings node with your api.seedance.nz token into api_config. The pack's dependencies are plain HTTP/image-stack stuff.

Common issues

• Blank images with no error - skip_error is likely on, swallowing failures. Flip it off to see what actually broke.
• Edit mode ignoring your references - check you're in image_edit, not text_to_image; the t2i mode ignores the image slots entirely.
• Cost surprises - the shop bills per image plus upload size for references. Ten reference images on a big 2K render adds up faster than people expect.

It's a "spend a few cents instead of hiring a photographer" node, and for product shots it's genuinely the best thing in this pack at that job. If you're doing e-commerce listings, this is the one you'll actually reach for.
