GPT-2 (AMPS)
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.

Size
How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.

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
About this model
GPT-2 (AMPS) was published by University of California (UC) Berkeley, in United States of America, in November 2021. The organisation is categorised as academia.
It works in Mathematics, Language, and is recorded as doing language modeling/generation, Quantitative reasoning.
It builds on GPT-2 (1.5B), which is why it shares that model's general shape and size.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
Answers
GPT-2 (AMPS) — common questions
How many parameters does GPT-2 (AMPS) have?
GPT-2 (AMPS) has 1.5M 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 GPT-2 (AMPS)?
GPT-2 (AMPS) was published by University of California (UC) Berkeley, based in United States of America, categorised as academia.
When was GPT-2 (AMPS) released?
GPT-2 (AMPS) was published in November 2021. 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 GPT-2 (AMPS) used for?
GPT-2 (AMPS) works in Mathematics, Language, and is recorded as handling language modeling/generation, Quantitative reasoning. These are the areas it was designed around; they describe intent rather than a hard boundary.
What GPU do I need to run GPT-2 (AMPS)?
None. GPT-2 (AMPS) 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 GPT-2 (AMPS) open source?
The licensing for GPT-2 (AMPS) was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
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.
