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 it does

The problem areas the model was built for. A model can carry several of each.

Domain
Biology
Task
Protein-RNA binding affinity prediction

Size

How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.

Training data
1,966,080,310 tokens

Summary: 1. Chain pairs: 30,000 2. Poses per pair: 3 Total datapoints: 30,000 × 3 = 90,000 3. Tokens per datapoint: - Protein residues: 200 - RNA bases: 100 Total tokens per datapoint: 200 + 100 = 300 4. Final calculation: 90,000 datapoints × 300 tokens/datapoint = 27,000,000 tokens

What the numbers mean

Where it came from

CoPRA was published by Tsinghua University,University College London (UCL),Monash University,Beijing University of Posts and Telecommunications, in China, in August 2024. The organisation is categorised as academia,Academia,Academia,Academia.

It works in Biology, and is recorded as doing protein-RNA binding affinity prediction.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

What went into building it

Around 1,966,080,310 tokens went into training it.

Answers

CoPRA — common questions

01

What GPU do I need to run CoPRA?

None. CoPRA 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.

02

Is CoPRA open source?

The licensing for CoPRA was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

03

How many parameters does CoPRA have?

No parameter count has been published for CoPRA, which is why no memory or speed figure appears on this page.

04

Who created CoPRA?

CoPRA was published by Tsinghua University,University College London (UCL),Monash University,Beijing University of Posts and Telecommunications, based in China, categorised as academia,Academia,Academia,Academia.

05

When was CoPRA released?

CoPRA was published in August 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

06

What is CoPRA used for?

CoPRA works in Biology, and is recorded as handling protein-RNA binding affinity prediction. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

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.
