EchoMimicV3
1.3B-parameter human animation model from Ant Group that fits a 12 GB GPU through its Gradio UI.
A 1.3B model from Ant Group that animates people from audio and other inputs.
EchoMimicV3 is Ant Group's unified multi-modal, multi-task human animation model with 1.3 billion parameters. It suits developers who want talking-person video on a single consumer GPU.
What it is
The README says one model covers several animation tasks, and documents a 12 GB VRAM route through a Gradio UI and a 16 GB route through ComfyUI. It ships quick-inference scripts for the flash and preview variants.
Who it's for
Suits technical users and researchers running human animation locally. It does not suit non-technical presenters: there are no voices, templates or editor, and installation needs CUDA 12.1+ and manual weight downloads.
Key features
Unified animation model
One set of weights handles several human-animation tasks.
12 GB VRAM route
A Gradio UI documents running in 12 GB of VRAM.
ComfyUI support
A community ComfyUI node runs it in 16 GB.
Flash and preview variants
Separate quick-inference scripts for each variant.
Windows install guide
The README has a Windows installation section.
Apache-2.0 models
The README grants use of the models under Apache-2.0.

Our honest verdict
What's great
- Apache-2.0 for the models, with the README claiming no rights over generated content.
- Smaller 1.3B model with a documented 12 GB VRAM path.
- Offers both Gradio and ComfyUI routes.
- Earlier EchoMimic and EchoMimicV2 repos from the same team show sustained work.
Where it falls short
- The README lists A100, RTX 4090D and V100 GPUs; consumer cards below 12 GB are not covered.
- Needs CUDA 12.1+, Python 3.10 or 3.11 and several multi-gigabyte weight downloads.
- No speech synthesis, editor or hosted service; you supply audio.
- A research release, so expect rough edges and thin documentation.
Pricing & license
Free under Apache-2.0. The README lists no hosted or paid plan, so the only cost is your own or rented GPU time.

FAQ
How much VRAM does EchoMimicV3 need?
The README says a Gradio UI route works in 12 GB of VRAM and a ComfyUI route in 16 GB.
Is EchoMimicV3 free for commercial use?
The README states the models are under Apache-2.0 and that you keep freedom over generated content, within that licence.
Is it better than EchoMimicV2?
The README does not benchmark it against V2; check the paper on the project page before choosing.
