X-Portrait
No estimate
No hardware requirements for this model
This model's weights are open, but no parameter count has been published for it. Every memory and speed figure starts from that number, so we would rather show nothing than a fabricated estimate.
On record
Full specification
Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

What the numbers mean
About this model
X-Portrait was published by ByteDance, in China, in July 2024. The organisation is categorised as industry.
It works in Video, Vision, and is recorded as doing portrait animation, Video generation, Image-to-video.
Published weights mean the model runs on your machine rather than someone else's, which is what makes the hardware question below answerable at all.
Answers
X-Portrait — common questions
How many parameters does X-Portrait have?
No parameter count has been published for X-Portrait, which is why no memory or speed figure appears on this page.
Who created X-Portrait?
X-Portrait was published by ByteDance, based in China, categorised as industry.
When was X-Portrait released?
X-Portrait was published in July 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
What is X-Portrait used for?
X-Portrait works in Video, Vision, and is recorded as handling portrait animation, Video generation, Image-to-video. These are the areas it was designed around; they describe intent rather than a hard boundary.
Where can I download X-Portrait?
The weights for X-Portrait are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.
What GPU do I need to run X-Portrait?
We cannot say. X-Portrait has open weights, but no parameter count has been published for it, and every memory and speed calculation starts from that number. We would rather show nothing than a fabricated estimate.
Is X-Portrait open source?
Its weights are published, so X-Portrait can be downloaded and run on your own hardware. Note that open weights is not the same as open source in the full sense — it says nothing about the training data, the training code, or the commercial terms attached.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
