InstructGPT 350M
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
Where it came from
InstructGPT 350M was published by OpenAI, in United States of America, in January 2022. industry is the category the publisher falls under.
It works in Language, and is recorded as doing language modeling/generation.
It builds on GPT-3 Medium, 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
InstructGPT 350M — common questions
When was InstructGPT 350M released?
InstructGPT 350M was published in January 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.
What is InstructGPT 350M used for?
InstructGPT 350M works in Language, and is recorded as handling language modeling/generation. These are the areas it was designed around; they describe intent rather than a hard boundary.
What GPU do I need to run InstructGPT 350M?
None. InstructGPT 350M 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 InstructGPT 350M open source?
The licensing for InstructGPT 350M 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 InstructGPT 350M have?
InstructGPT 350M has 350M 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 InstructGPT 350M?
InstructGPT 350M was published by OpenAI, based in United States of America, categorised as industry.
