MiniMax Hailuo 2.3 Fast (Channel Edition)

MiniMax's Hailuo 2.3 Fast, image-to-video, served through SiliconFlow's BizyAir channel. Hailuo is one of the most popular hosted video models out of China - strong motion, natural physics, a style people actually recognize - and the Fast variant trades a little fidelity for speed. The "Channel Edition" framing means your SiliconFlow key is the only credential you need; you never talk to MiniMax directly.

This is the node for turning a single strong still into a clip fast, when speed matters more than the absolute best quality. If you've got a good image from your local pipeline and you want motion on it in a couple of minutes instead of a local video render session, this is the shortest path in the pack.

How it works

Cloud wrapper, same as every BizyTRD node. Feed it a first_frame_image (required) and a prompt, and the request goes to the BizyAir channel where Hailuo animates the frame. The VIDEO result returns to ComfyUI. The constraints live in the tooltips and they're worth reading: the input image must be JPG/JPEG/PNG/WebP, under 20 MB, with short edges over 300 px and an aspect ratio between 2:5 and 5:2. Prompts can run to 2000 characters and - this is a Hailuo thing - respond to "conch mirror instruction writing," the descriptive prompt style from MiniMax's consumer app, full of camera moves and shot descriptions.

resolution supports 768P and 1080p, but with a catch spelled out in the tooltip: only 768P is available at 10 seconds - 1080p clips max out at 6 seconds. duration is a combo (default 6).

Inputs and outputs

• first_frame_image (required) - the frame to animate.
• prompt (required, multiline, up to 2000 chars).
• resolution (required, default 768P) and duration (required, default 6).
• Outputs: video (VIDEO), request_id, urls.

Installing BizyAirPlus

ComfyUI Manager: "BizyAirPlus", or:

cd /path/to/ComfyUI/custom_nodes
git clone https://github.com/siliconflow/BizyAirPlus.git
cd BizyAirPlus
python -m pip install -r requirements.txt

Restart, account at bizyair.ai, API key, BizyAirPlus button ON. Dependencies: bizyair-cloudberry, bizytrd; no model files.

Common issues

The 20 MB / 300 px / 2:5–5:2 constraints on the first frame are the real traps - an over-ratio panorama or a huge PNG gets rejected with a confusing cloud error. Fix the image upstream, don't fight the node. And the resolution/duration coupling (1080p only at 6s) surprises everyone once. Then the pack standard: missing button → dependency environment (pip show bizyair-cloudberry); cloud failures → key, network, console; and it's metered, so keep an eye on 1080p pricing.
