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

Background

DrugTar was published by Isfahan University of Technology, in Iran (Islamic Republic of), in September 2024. academia is the category the publisher falls under.

It works in Biology, and is recorded as doing protein property prediction, Drug discovery.

It is derived from ESM2-650M rather than trained from scratch, which is the usual way a specialised model is produced.

Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.

What went into building it

Around 4,068 tokens went into training it.

Answers

DrugTar — common questions

01

How many parameters does DrugTar have?

DrugTar 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.

02

Who created DrugTar?

DrugTar was published by Isfahan University of Technology, based in Iran (Islamic Republic of), categorised as academia.

03

When was DrugTar released?

DrugTar 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.

04

What is DrugTar used for?

DrugTar works in Biology, and is recorded as handling protein property prediction, Drug discovery. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

05

What GPU do I need to run DrugTar?

None. DrugTar 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.

06

Is DrugTar open source?

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