zhenzhen-wan-2.7-spicy-i2v-lowprice

The node name says "spicy," and the README is more specific: 宽审核 - "wide audit" - which is the storefront's label for a model that passes more prompts than the strict default gate. The pitch in the changelog is aimed at one crowd: 电商出海必备, "a must for e-commerce going overseas." If your product or marketing content keeps tripping the standard content filter, Comfly_wan_2_7_spicy_i2v_lowprice is Wan 2.7's image-to-video model with a looser review gate, sold cheaply through Zhenzhen's domestic storefront.

Let's be clear about what it is and isn't. It's a legitimate alternative gate for borderline-but-legal commercial content - swimwear, beauty, certain pharma or supplement categories, that kind of thing. It's not a promise that anything goes; "spicy" here means "spicier than the default," not "no rules."

How it works

This is a first-frame-to-video node. You connect the required first_image, write a prompt describing the motion, and the node animates that frame into a clip with optional audio. Outputs are video, video_url, task_id, and response.

Inputs that matter:

• first_image - required, and it's the whole show. The quality and composition of this single frame is what the video inherits.
• prompt - what happens. Describe motion, not the static scene; the model already sees the image.
• seconds - 2 through 15. Short clips are cheap tests; go longer once the prompt is working.
• resolution - 720p or 1080p.
• negative_prompt - available here, which is rare in the cloud tier. Use it to push away artifacts or unwanted content.
• audio_url - optional reference audio; leave empty for no/silent audio unless the model generates it.
• prompt_extend - off by default. Turn it on if you want the backend to flesh your prompt out.
• seed - -1 means random; pin it to reproduce.

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 (or set SEEDANCE_API_KEY) - like every node in this low-price family, there's no direct key field.

Troubleshooting

The family's usual trap applies: no api_config connection means an immediate "empty api_key" error, and the settings node is the fix. Beyond that, the spicy node's specific gotcha is expectation management - content that's clearly against policy will still bounce, and the refund/failure behavior is the same as the strict nodes. If a prompt fails, try rewording rather than fighting it; the gate is wider, not open.

The practical advice: this is the node you reach for when a legitimately borderline product shot gets rejected on the standard tier. Use it for that, keep your content defensible, and remember the whole pack's standing wisdom - when a run 500s, just re-run it. Failures don't charge you.
