RoBERTa (PFAM)

Open weights IBM Research,ETH Zurich December 2020

No estimate

No hardware requirements for this model

This model's weights are open, but no parameter count has been published for it. Every memory and speed figure starts from that number, so we would rather show nothing than a fabricated estimate.

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.

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.

Training data
tokens

31M sequences with an estiamted length of 300: 31M*300=9300000000

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.

Training compute

What the numbers mean

About this model

RoBERTa (PFAM) was published by IBM Research,ETH Zurich, in United States of America, in December 2020. The organisation is categorised as industry,Academia.

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

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached.

Training and provenance

The training run consumed about 1.2 × 10¹⁹ FLOP, on NVIDIA P100. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

Answers

RoBERTa (PFAM) — common questions

01

Who created RoBERTa (PFAM)?

RoBERTa (PFAM) was published by IBM Research,ETH Zurich, based in United States of America, categorised as industry,Academia.

02

When was RoBERTa (PFAM) released?

RoBERTa (PFAM) was published in December 2020. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

03

What is RoBERTa (PFAM) used for?

RoBERTa (PFAM) 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.

04

Where can I download RoBERTa (PFAM)?

The weights for RoBERTa (PFAM) are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

05

How much compute was used to train RoBERTa (PFAM)?

Around 1.2 × 10¹⁹ FLOP, on NVIDIA P100. 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.

06

What GPU do I need to run RoBERTa (PFAM)?

We cannot say. RoBERTa (PFAM) has open weights, but no parameter count has been published for it, and every memory and speed calculation starts from that number. We would rather show nothing than a fabricated estimate.

07

Is RoBERTa (PFAM) open source?

Its weights are published, so RoBERTa (PFAM) can be downloaded and run on your own hardware. Note that open weights is not the same as open source in the full sense — it says nothing about the training data, the training code, or the commercial terms attached.

08

How many parameters does RoBERTa (PFAM) have?

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

The other direction

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.
