DNCON2
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.

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 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
DNCON2 was published by University of Missouri, in United States of America, in May 2018. It comes out of academia.
It works in Biology, and is recorded as doing proteins, Protein folding prediction.
The weights being open is what puts this page in the calculator rather than only in the catalogue: it is a model you can actually hold.
How it was trained
The training run consumed about 9.5 × 10¹⁶ FLOP. That figure describes the cost of creating it and has no bearing on how quickly it generates text.
The training set ran to roughly 444,030,000 tokens.
Answers
DNCON2 — common questions
How much compute was used to train DNCON2?
Around 9.5 × 10¹⁶ FLOP. 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.
What GPU do I need to run DNCON2?
We cannot say. DNCON2 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.
Is DNCON2 open source?
Its weights are published, so DNCON2 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.
How many parameters does DNCON2 have?
No parameter count has been published for DNCON2, which is why no memory or speed figure appears on this page.
Who created DNCON2?
DNCON2 was published by University of Missouri, based in United States of America, categorised as academia.
When was DNCON2 released?
DNCON2 was published in May 2018. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
What is DNCON2 used for?
DNCON2 works in Biology, and is recorded as handling proteins, Protein folding prediction. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
Where can I download DNCON2?
The weights for DNCON2 are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.
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.
