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.

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.

Morse translation

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

??? Might need to make a guesstimate here.

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
6 × 10⁸ FLOP

The paper mentions using an IBM 704, which can execute up to 12,000 floating-point additions per second (https://wikiless.org/wiki/IBM_704). My best guess as to how long it ran for ranges between 1h to 2 days, which when plugged into guesstimate (https://www.getguesstimate.com/models/19625), i.e., taking the log mean, gives a mean estimate of 600M

What the numbers mean

About this model

Pandemonium (morse) was published by Massachusetts Institute of Technology (MIT), in United States of America, in February 1959. academia is the category the publisher falls under.

It works in Language, and is recorded as doing morse translation.

Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.

What went into building it

Training it took roughly 6 × 10⁸ FLOP of computation — a measure of what producing the model cost, not of how fast it answers.

The reason it appears in this catalogue at all is highly cited,Historical significance.

Answers

Pandemonium (morse) — common questions

01

Who created Pandemonium (morse)?

Pandemonium (morse) was published by Massachusetts Institute of Technology (MIT), based in United States of America, categorised as academia.

02

When was Pandemonium (morse) released?

Pandemonium (morse) was published in February 1959. 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 Pandemonium (morse) used for?

Pandemonium (morse) works in Language, and is recorded as handling morse translation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

04

How much compute was used to train Pandemonium (morse)?

Around 6 × 10⁸ 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.

05

What GPU do I need to run Pandemonium (morse)?

None. Pandemonium (morse) 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.

06

Is Pandemonium (morse) open source?

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

07

How many parameters does Pandemonium (morse) have?

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

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.
