LCNP NORB
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.

(2) The NORB normalized-uniform dataset [2], which consists of stereoscopic grayscale images of 50 toys, belonging to 5 categories. Each of the 48,600 images (24,300 for training and 24,300 for testing) shows one toy under different lighting conditions, elevations and azimuths.
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
Where it came from
LCNP NORB was published by its authors, in November 2009.
It works in Vision, and is recorded as doing object recognition.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Training and provenance
Producing it required around 2.5 × 10¹⁵ FLOP of arithmetic, which is a statement about the training budget rather than about inference.
The training set ran to roughly 24,300 tokens.
It is tracked in the underlying dataset for one reason in particular: historical significance.
Answers
LCNP NORB — common questions
What GPU do I need to run LCNP NORB?
None. LCNP NORB 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 LCNP NORB open source?
The licensing for LCNP NORB 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 LCNP NORB have?
LCNP NORB has 16.8M parameters. Locally connected: 128*128*4*4*4*10 + 64*64*8*4*4*4 + 32*32*16*4*4*8 + 16*16*32*4*4*16=16777216 Classification head: 16*16*32*5=40960 Total: 16777216+40960=16818176 "five regular layers with the dimensions 256×256, 128×128, . . ., 16×16." "size of the receptive field to be 4 × 4 neurons". 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.
When was LCNP NORB released?
LCNP NORB was published in November 2009. 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 LCNP NORB used for?
LCNP NORB works in Vision, and is recorded as handling object recognition. 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.
How much compute was used to train LCNP NORB?
Around 2.5 × 10¹⁵ 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.
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.
