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.

Training data
tokens

"We trained two different ProCALM models – one on 9 billion tokens of enzyme sequences from Uniref, and one on 1.5 billion tokens of enzyme sequences from Swissprot Train"

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

What this model is

ProCALM (Uniref9B) was published by Profluent Bio,California Institute of Technology, in United States of America, in October 2024. The organisation is categorised as industry,Academia.

It works in Biology, and is recorded as doing proteins, Protein generation.

Its starting point was ProGen2-base — most models at this scale are adapted from an existing base rather than built from nothing.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

Answers

ProCALM (Uniref9B) — common questions

01

Who created ProCALM (Uniref9B)?

ProCALM (Uniref9B) was published by Profluent Bio,California Institute of Technology, based in United States of America, categorised as industry,Academia.

02

When was ProCALM (Uniref9B) released?

ProCALM (Uniref9B) was published in October 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.

03

What is ProCALM (Uniref9B) used for?

ProCALM (Uniref9B) works in Biology, and is recorded as handling proteins, Protein generation. These are the areas it was designed around; they describe intent rather than a hard boundary.

04

What GPU do I need to run ProCALM (Uniref9B)?

None. ProCALM (Uniref9B) 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.

05

Is ProCALM (Uniref9B) open source?

The licensing for ProCALM (Uniref9B) was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

06

How many parameters does ProCALM (Uniref9B) have?

ProCALM (Uniref9B) has 764M 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.
