WebGPT
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
About this model
WebGPT was published by OpenAI, in the country recorded as United States of America, during July 2022. It comes out of an organisation categorised as industry.
It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Question answering, Search.
Its starting point was an existing base model, GPT-3 175B (davinci). That is why it shares the base model's general shape and size.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
Answers
WebGPT — common questions
WebGPT— what is it used for?
It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Question answering, Search. These are the areas it was designed around; they describe intent rather than a hard boundary.
WebGPT— what GPU do I need to run it?
None. This 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.
WebGPT— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
WebGPT— how many parameters does it have?
It has a parameter count of 175B. same as the base model. 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.
WebGPT— who created it?
It was published by OpenAI, based in United States of America, an organisation categorised as industry.
WebGPT— when was it released?
It was published in July 2022. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
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.
