Concurrent Submit | zhenzhen-sd2-seedream-v5-pro-lowprice

ByteDance's Seedream V5 Pro image model, sold through the domestic discount site at 75折 off, and - the part the README is genuinely excited about - with a wide-audit mode that makes it the go-to for e-commerce listings that have to survive platform content review (the changelog literally tags it "电商出海必备," a must-have for cross-border e-commerce). If you're generating product shots in bulk with strict moderation standards, this is the node the pack is aimed at.

The "lowprice" node family all share one config pattern: instead of a raw apikey field, they take an api_config of type ZHENZHEN_SEEDANCE2_CONFIG, built with the Comfly Seedance2 Low Price Settings node (Comfly_seedance2_low_price_settings) which carries base_url + api_key. One settings node, feed every low-price node.

Concurrent-wise: image pool (30 workers), COMFLY_IMAGE_FUTURE task output, collect with Concurrent Collect Images (ComflyConcurrent_Image_Await) to get image_1…image_30 in order.

The inputs

• mode - text_to_image or image_edit. The edit path accepts reference images.
• prompt - the listing copy / instruction. Multiline.
• model_family - seedream-v5-pro (domestic) vs dola-seedream-5.0-pro (overseas). Switch to the overseas lane if you're outside the domestic site's reach or need looser auditing.
• resolution - 1k, 2k, or custom (which unlocks width/height).
• width / height - 240–8192, step 8, default 1024×1024. Only honored meaningfully in custom mode.
• output_format - png / jpeg.
• image1 … image10 - up to ten reference images for edits. That's a real multi-reference edit workload.
• seed - execution seed for ComfyUI cache control; the tooltip notes it's a compatibility seed not sent to APIs without a native seed.
• skip_error - usual.

Install

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

Or ComfyUI Manager → search Comfyui-zhenzhen → restart. Then create the settings node with your domestic-site token (api.seedance.nz) - or the overseas token plus the global/overseas model family if that's your route.

Gotchas

• The domestic site needs a China-friendly route. If you're getting connection errors, the README's standing advice applies - 443/timeouts are almost always your path to their server, and the overseas token + base_url is the more reliable combo outside China.
• Resolution cost. 2K Seedream is visibly better and measurably pricier; for listing thumbnails 1k is plenty and the batch math favors it heavily.
• Ten reference images is a real upload. Multi-ref edits upload every image to their server, and uploads carry their own token cost on the reseller. Keep references lean when you're just swapping a background.
