GigaChat 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
Where it came from
GigaChat Pro was published by Sber, in Russia, in December 2023. The organisation is categorised as industry,Government.
It works in Language, and is recorded as doing language modeling/generation, Question answering, Chat.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
Answers
GigaChat Pro — common questions
Is GigaChat Pro open source?
No. GigaChat Pro has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does GigaChat Pro have?
GigaChat Pro has 29B parameters. "GigaChat Pro is a transformer containing 29 billion parameters". 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 GigaChat Pro?
GigaChat Pro was published by Sber, based in Russia, categorised as industry,Government.
When was GigaChat Pro released?
GigaChat Pro was published in December 2023. 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 GigaChat Pro used for?
GigaChat Pro works in Language, and is recorded as handling language modeling/generation, Question answering, Chat. 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.
What GPU do I need to run GigaChat Pro?
None. GigaChat 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.
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.
