CPCProt
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
CPCProt was published by University of Toronto, in Canada, in November 2020. The organisation is categorised as academia.
It works in Biology, and is recorded as doing protein or nucleotide language model (pLM/nLM).
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
How it was trained
Around 2,963,049,428 tokens went into training it.
Answers
CPCProt — common questions
How many parameters does CPCProt have?
CPCProt has 1.7M 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 CPCProt?
CPCProt was published by University of Toronto, based in Canada, categorised as academia.
When was CPCProt released?
CPCProt was published in November 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 CPCProt used for?
CPCProt works in Biology, and is recorded as handling protein or nucleotide language model (pLM/nLM). 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.
What GPU do I need to run CPCProt?
None. CPCProt 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 CPCProt open source?
The licensing for CPCProt 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.
