MEGNet (crystal formation energy model)
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
What this model is
MEGNet (crystal formation energy model) was published by University of California San Diego, in United States of America, in April 2019. It comes out of academia.
It works in Materials science, and is recorded as doing molecular property prediction.
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 4.5 × 10¹⁷ FLOP, on NVIDIA GeForce GTX 1080 Ti. That figure describes the cost of creating it and has no bearing on how quickly it generates text.
It was trained on about 60,000 tokens of text.
Answers
MEGNet (crystal formation energy model) — common questions
How much compute was used to train MEGNet (crystal formation energy model)?
Around 4.5 × 10¹⁷ FLOP, on NVIDIA GeForce GTX 1080 Ti. 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 MEGNet (crystal formation energy model)?
None. MEGNet (crystal formation energy model) 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.
Is MEGNet (crystal formation energy model) open source?
The licensing for MEGNet (crystal formation energy model) was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
How many parameters does MEGNet (crystal formation energy model) have?
MEGNet (crystal formation energy model) has 26.1K parameters. Calculations here: https://docs.google.com/document/d/1BTmyZ9KVTIwkp9z9tRRFsWM5A0QcXiufXrIhujffyso/edit?tab=t.0#heading=h.913mrln2g0cv. 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.
Who created MEGNet (crystal formation energy model)?
MEGNet (crystal formation energy model) was published by University of California San Diego, based in United States of America, categorised as academia.
When was MEGNet (crystal formation energy model) released?
MEGNet (crystal formation energy model) was published in April 2019. 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 MEGNet (crystal formation energy model) used for?
MEGNet (crystal formation energy model) works in Materials science, and is recorded as handling molecular property prediction. 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.
