Zhenzhen WanX 2.6 Video

Here's the odd one out in this pack, and in a good way. Every other node in Comfyui-zhenzhen routes through Zhenzhen's own storefronts and takes a Zhenzhen API key. Comfly_wan2_6_API is the exception the README calls out explicitly: it takes an official Alibaba Bailian (百炼 / DashScope) API key and talks straight to Alibaba's cloud. It was added in late 2025 as the author's own testing node before Wan 2.6 hit the storefronts - "支持官方百炼的APIKEY，暂时贞贞网站还没上，我测试用的."

That matters because of what Wan is. The open Wan line froze at 2.2 - 2.5, 2.6, and 2.7 have no weights. This node is the only way you can reasonably run Wan 2.6 inside ComfyUI: through Alibaba's own pay-per-task API, with your own key, no middleman.

How it works

The node submits a generation task to Alibaba's DashScope API and polls the task endpoint (dashscope.aliyuncs.com/api/v1/tasks/{id}) until the video's ready, then returns it as video, video_url, and task_id. The headline feature is native audio - Wan 2.6 generates video with synchronized sound, which is why audio_enabled defaults to true.

Inputs worth setting:

• api_key - your Bailian key, not a Zhenzhen key. This is the node's whole personality.
• prompt - the default is a long Chinese example; replace it. Works in English.
• resolution - 1080P or 720P. duration - 5, 10, or 15 seconds.
• prompt_extend - on by default; Alibaba expands your prompt before generation. Usually helps.
• shot_type - single or multi. Multi shots change up framing within the clip, which is nice for anything with motion.
• image (optional IMAGE) - connects an image-to-video run; leave empty for text-to-video.
• audio_url (optional) - feed a reference audio if you want the clip to match it.

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 models to download. Get a Bailian API key from Alibaba Cloud's DashScope console and paste it into api_key. Because it uses your own cloud account, billing is whatever Alibaba charges - no Zhenzhen margin on top.

Troubleshooting

The number-one confusion is the key: people paste in their Zhenzhen key and get auth errors. It has to be an Alibaba Bailian key. Second, the standard proxy caveat from the README flips here - Alibaba's Chinese endpoints are reachable without a VPN, which is the one nice thing about bypassing the overseas storefront. If a generation fails mid-way, Alibaba only bills completed tasks, and the task_id output lets you chase any job in the DashScope console. skip_error is there if you want failures to return empty results instead of aborting.

One warning from the KB: Wan's post-2.2 series is where Alibaba went commercial-only, and the local Wan community doesn't love that. But if you specifically want 2.6's audio-synced output, this is the cleanest door.
