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

Structure-Informed Protein Language Model was published by Mila - Quebec AI (originally Montreal Institute for Learning Algorithms),University of Montreal / Université de Montréal,IBM Research,HEC Montreal,CIFAR AI Research, in Canada, in February 2024. It comes out of academia,Academia,Industry,Academia,Research collective.

It works in Biology, and is recorded as doing protein or nucleotide language model (pLM/nLM).

Its starting point was ESM2-650M — most models at this scale are adapted from an existing base rather than built from nothing.

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

Answers

Structure-Informed Protein Language Model — common questions

01

When was Structure-Informed Protein Language Model released?

Structure-Informed Protein Language Model was published in February 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.

02

What is Structure-Informed Protein Language Model used for?

Structure-Informed Protein Language Model works in Biology, and is recorded as handling protein or nucleotide language model (pLM/nLM). These are the areas it was designed around; they describe intent rather than a hard boundary.

03

What GPU do I need to run Structure-Informed Protein Language Model?

None. Structure-Informed Protein Language Model 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.

04

Is Structure-Informed Protein Language Model open source?

The licensing for Structure-Informed Protein Language Model was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

05

How many parameters does Structure-Informed Protein Language Model have?

Structure-Informed Protein Language Model has 650M 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.

06

Who created Structure-Informed Protein Language Model?

Structure-Informed Protein Language Model was published by Mila - Quebec AI (originally Montreal Institute for Learning Algorithms),University of Montreal / Université de Montréal,IBM Research,HEC Montreal,CIFAR AI Research, based in Canada, categorised as academia,Academia,Industry,Academia,Research collective.
