SexNet classification
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
Background
SexNet classification was published by its authors, in October 1990.
It works in Vision, and is recorded as doing image classification.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
Training and provenance
The training set ran to roughly 80 tokens.
Its inclusion criterion is historical significance,Highly cited.
Answers
SexNet classification — common questions
Is SexNet classification open source?
The licensing for SexNet classification 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 SexNet classification have?
SexNet classification has 1.6K parameters. Largest classification model: 40*40 + 40=1640 (Figure 2). 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 SexNet classification released?
SexNet classification was published in October 1990. 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 SexNet classification used for?
SexNet classification works in Vision, and is recorded as handling image classification. These are the areas it was designed around; they describe intent rather than a hard boundary.
What GPU do I need to run SexNet classification?
None. SexNet classification 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.
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.
