HGRN2 1B
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.

Training compute
The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

What the numbers mean
Background
HGRN2 1B was published by Shanghai AI Lab,Massachusetts Institute of Technology (MIT),Taptap, in China, in April 2024. It comes out of academia,Academia,Industry.
It works in Language, and is recorded as doing language modeling/generation, Question answering.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
Training and provenance
The training run consumed about 6 × 10²¹ FLOP. That figure describes the cost of creating it and has no bearing on how quickly it generates text.
The training set ran to roughly 100,000,000,000 tokens.
Answers
HGRN2 1B — common questions
What GPU do I need to run HGRN2 1B?
None. HGRN2 1B 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 HGRN2 1B open source?
The licensing for HGRN2 1B was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
How many parameters does HGRN2 1B have?
HGRN2 1B has 1B parameters. 1B. 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 HGRN2 1B?
HGRN2 1B was published by Shanghai AI Lab,Massachusetts Institute of Technology (MIT),Taptap, based in China, categorised as academia,Academia,Industry.
When was HGRN2 1B released?
HGRN2 1B was published in April 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 HGRN2 1B used for?
HGRN2 1B works in Language, and is recorded as handling language modeling/generation, Question answering. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
How much compute was used to train HGRN2 1B?
Around 6 × 10²¹ FLOP. That measures what producing the model cost and says nothing about how quickly it answers once trained — inference speed comes from memory bandwidth, not from the training budget.
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.
