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.

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.

Task
Protein or nucleotide language model (pLM/nLM)

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.

Parameters
250M

"Following the RoBERTa-base setting, the hidden size, feed forward dimension, number of encoder layers, and attention heads of the base models are set as 768, 3072, 12, 12 re- spectively (denoted as MLM-base for MLM and PMLM-base for PMLM). A larger model named PMLM-large is pre-trained with the same setting except using 34 as the number of encoder layers."

Training data

Training compute

The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

What the numbers mean

Where it came from

PMLM-large was published by Microsoft Research Asia,Nanyang Technological University,Xi’an Jiaotong University,Sun Yat-sen University, in China, in October 2021. industry,Academia,Academia,Academia is the category the publisher falls under.

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

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

What went into building it

The training run consumed about 3.8 × 10²¹ FLOP, on NVIDIA V100. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

Answers

PMLM-large — common questions

01

What GPU do I need to run PMLM-large?

None. PMLM-large 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 PMLM-large open source?

The licensing for PMLM-large 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 PMLM-large have?

PMLM-large has 250M parameters. "Following the RoBERTa-base setting, the hidden size, feed forward dimension, number of encoder layers, and attention heads of the base models are set as 768, 3072, 12, 12 re- spectively (denoted as MLM-base for MLM and PMLM-base for PMLM). A larger model named PMLM-large is pre-trained with the same setting except using 34 as the number of encoder layers.". 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.

04

Who created PMLM-large?

PMLM-large was published by Microsoft Research Asia,Nanyang Technological University,Xi’an Jiaotong University,Sun Yat-sen University, based in China, categorised as industry,Academia,Academia,Academia.

05

When was PMLM-large released?

PMLM-large was published in October 2021. 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 PMLM-large used for?

PMLM-large 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.

07

How much compute was used to train PMLM-large?

Around 3.8 × 10²¹ FLOP, on NVIDIA V100. That measures what producing the model cost and says nothing about how quickly it answers once trained — inference speed comes from memory bandwidth, not from the training budget.
