GPT-3 13B
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.

What the numbers mean
Background
GPT-3 13B was published by OpenAI, in United States of America, in June 2020. It comes out of industry.
It works in Language, and is recorded as doing text autocompletion, Language modeling/generation.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
How it was trained
The training run consumed about 2.3 × 10²² FLOP, on NVIDIA Tesla V100 DGXS 32 GB. That figure describes the cost of creating it and has no bearing on how quickly it generates text.
Around 300,000,000,000 tokens went into training it.
Answers
GPT-3 13B — common questions
Is GPT-3 13B open source?
The licensing for GPT-3 13B 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 GPT-3 13B have?
GPT-3 13B has 12.9B parameters. 13B. 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-3 13B?
GPT-3 13B was published by OpenAI, based in United States of America, categorised as industry.
When was GPT-3 13B released?
GPT-3 13B was published in June 2020. 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-3 13B used for?
GPT-3 13B works in Language, and is recorded as handling text autocompletion, Language modeling/generation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
How much compute was used to train GPT-3 13B?
Around 2.3 × 10²² FLOP, on NVIDIA Tesla V100 DGXS 32 GB. 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-3 13B?
None. GPT-3 13B 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.

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.
