HunyuanCustom

Overview

Tencent’s HunyuanCustom is one of those things that feels like it came from the future. You feed it a photo or a prompt or even a clip and it spits out a full video where the subject stays the same from start to finish.

What makes this one special is the total control over your subject.

Most tools mess up when the same face has to show up in every frame. Not this one. HunyuanCustom locks in the person or thing and keeps it looking the same the whole time. Even if you switch from text to video to audio input it stays solid.

Input types it can handle:

• Text. Describe what you want and it makes the scene.
• Image. Upload a face or reference and it uses that look.
• Audio. Give it a voice and it syncs lips or actions to it.
• Video. Drop a clip and swap in new people or visuals.

The tech behind it builds off Tencent’s earlier HunyuanVideo. But this one packs extra stuff:

• A text-image combo system that helps describe scenes while locking in visual style
• AudioNet that makes lips and gestures match the voice
• A setup that blends in video input smoothly
• Identity lock module that makes sure faces don’t shift mid-frame
• Support for more than one person in a scene

Hunyuan Custom can be handy for stuff like:

• Virtual ads. Like influencers but AI.
• Singing faces. Upload music and the mouth moves right.
• Outfit previews. Show someone in new clothes as a moving model.
• Video edits. Swap in a face or add new people into old clips.

VRAM Requirements from Hunyuan Custom

A CUDA-compatible NVIDIA GPU is required. Testing was conducted on a machine with 8 GPUs. The minimum GPU memory needed is 24GB for 720x1280 resolution at 129 frames, though performance is slow. An 80GB GPU is recommended for better output quality.

Tencent Hunyuan License in Simple Terms

The Tencent Hunyuan Community License isn’t a regular open-source license and it’s not really business-friendly either. But here’s what you can and can’t do under it.

✅ What’s Allowed (With Rules)

You can use change and build on the model.
You can give it to others but only in approved areas. The EU UK and South Korea are not on that list.
You can use the results freely. Tencent doesn’t claim ownership.
You can use it in your own tools or services unless you’re one of the big players.

❌ Big Limit on Commercial Use

There’s a major rule in Section 4.

If your company has over 100 million monthly active users across all services you can’t use the model for business unless Tencent gives the green light.
No exceptions. You’ll need to ask first and wait for a yes.

So what does that mean?

If you’re small you’re probably ok to use it in your business. Just follow the license and the Acceptable Use Policy.
If you’re big you need permission. No use until Tencent says yes.

Also no sharing the model in Europe the UK or South Korea.
