What the numbers mean
What this model is
GPT-2 (1.5B, Curriculum Learning 45K) was published by Microsoft, in United States of America, in August 2021. industry is the category the publisher falls under.
It works in Language, and is recorded as doing language modeling/generation.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
How it was trained
Training it took roughly 2.4 × 10²¹ FLOP of computation, on NVIDIA V100 — a measure of what producing the model cost, not of how fast it answers.
The training set ran to roughly 157,000,000,000 tokens.
Answers
GPT-2 (1.5B, Curriculum Learning 45K) — common questions
When was GPT-2 (1.5B, Curriculum Learning 45K) released?
GPT-2 (1.5B, Curriculum Learning 45K) was published in August 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 (1.5B, Curriculum Learning 45K) used for?
GPT-2 (1.5B, Curriculum Learning 45K) works in Language, and is recorded as handling language modeling/generation. 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.
How much compute was used to train GPT-2 (1.5B, Curriculum Learning 45K)?
Around 2.4 × 10²¹ FLOP, on NVIDIA V100. 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.
What GPU do I need to run GPT-2 (1.5B, Curriculum Learning 45K)?
None. GPT-2 (1.5B, Curriculum Learning 45K) 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 (1.5B, Curriculum Learning 45K) open source?
No. GPT-2 (1.5B, Curriculum Learning 45K) has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does GPT-2 (1.5B, Curriculum Learning 45K) have?
GPT-2 (1.5B, Curriculum Learning 45K) has 1.5B 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 (1.5B, Curriculum Learning 45K)?
GPT-2 (1.5B, Curriculum Learning 45K) was published by Microsoft, based in United States of America, categorised as industry.
