Character-3
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
Where it came from
Character-3 was published by Hedra AI, in United States of America, in March 2025. industry is the category the publisher falls under.
It works in Video, Audio, and is recorded as doing video generation, Text-to-video.
The weights being open is what puts this page in the calculator rather than only in the catalogue: it is a model you can actually hold.
Answers
Character-3 — common questions
Where can I download Character-3?
The weights for Character-3 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 Character-3?
We cannot say. Character-3 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 Character-3 open source?
Its weights are published, so Character-3 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.
How many parameters does Character-3 have?
No parameter count has been published for Character-3, which is why no memory or speed figure appears on this page.
Who created Character-3?
Character-3 was published by Hedra AI, based in United States of America, categorised as industry.
When was Character-3 released?
Character-3 was published in March 2025.
What is Character-3 used for?
Character-3 works in Video, Audio, and is recorded as handling video generation, Text-to-video. These are the areas it was designed around; they describe intent rather than a hard boundary.
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.
