Solar Pro
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.
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
What this model is
Solar Pro was published by Upstage, in Korea (Republic of), in September 2024. industry is the category the publisher falls under.
It works in Language, and is recorded as doing language modeling/generation, Question answering, Translation.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Answers
Solar Pro — common questions
What GPU do I need to run Solar Pro?
None. Solar Pro 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 Solar Pro open source?
No. Solar Pro has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Solar Pro have?
Solar Pro has 22B parameters. 22B. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.
Who created Solar Pro?
Solar Pro was published by Upstage, based in Korea (Republic of), categorised as industry.
When was Solar Pro released?
Solar Pro was published in September 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 Solar Pro used for?
Solar Pro works in Language, and is recorded as handling language modeling/generation, Question answering, Translation. 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.
