Phoenix 1.0 Ultra
No estimate
No hardware requirements for this model
The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.

What the numbers mean
Background
Phoenix 1.0 Ultra was published by Leonardo AI, in Australia, in June 2024. It comes out of industry.
It works in Image generation, and is recorded as doing text-to-image, Image generation.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Answers
Phoenix 1.0 Ultra — common questions
What GPU do I need to run Phoenix 1.0 Ultra?
None. Phoenix 1.0 Ultra is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
Is Phoenix 1.0 Ultra open source?
No. Phoenix 1.0 Ultra has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Phoenix 1.0 Ultra have?
No parameter count has been published for Phoenix 1.0 Ultra, which is why no memory or speed figure appears on this page.
Who created Phoenix 1.0 Ultra?
Phoenix 1.0 Ultra was published by Leonardo AI, based in Australia, categorised as industry.
When was Phoenix 1.0 Ultra released?
Phoenix 1.0 Ultra was published in June 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 Phoenix 1.0 Ultra used for?
Phoenix 1.0 Ultra works in Image generation, and is recorded as handling text-to-image, Image generation. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.
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.
