Solar Pro 3
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
Background
Solar Pro 3 was published by Upstage, in the country recorded as Korea (Republic of), during January 2026. The category the publisher falls under is industry.
It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Question answering.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
Answers
Solar Pro 3 — common questions
Solar Pro 3— how many parameters does it have?
It has a parameter count of 102B. "Solar Pro 3 is Upstage's 102B Mixture-of-Experts large language model, activating only 12B parameters per token". 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.
Solar Pro 3— who created it?
It was published by Upstage, based in Korea (Republic of), an organisation categorised as industry.
Solar Pro 3— when was it released?
It was published in January 2026.
Solar Pro 3— what is it used for?
It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Question answering. 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.
Solar Pro 3— what GPU do I need to run it?
None. This 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.
Solar Pro 3— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
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.
