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.

Answers

CPDiffusion — common questions

01

What is CPDiffusion used for?

CPDiffusion works in Biology, and is recorded as handling protein design. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

02

What GPU do I need to run CPDiffusion?

None. CPDiffusion 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.

03

Is CPDiffusion open source?

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

04

How many parameters does CPDiffusion have?

CPDiffusion has 4M parameters. CPDiffusion trains a denoising diffusion model with 4 million learnable parameters from natural protein structures. 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.

05

Who created CPDiffusion?

CPDiffusion was published by Shanghai Jiao Tong University,University of New South Wales,University of Cambridge,Shanghai AI Lab, based in China, categorised as academia,Academia,Academia,Academia.

06

When was CPDiffusion released?

CPDiffusion was published in September 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.
