LIRA
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
LIRA was published by Instituto de Ciencias Aplicadas y Technologia, in Mexico, in July 2004. academia is the category the publisher falls under.
It works in Vision, and is recorded as doing character recognition (OCR).
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
Training and provenance
Around 1,020,000 tokens went into training it.
Answers
LIRA — common questions
Is LIRA open source?
The licensing for LIRA 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 LIRA have?
LIRA has 100K parameters. "For the first modification of the Rosenblatt perceptron 10 neurons were included into the R-layer. [...] The number of the A-layer neurons was 256,000" The relation between the S-layer and A-layer is hardcoded. 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 LIRA?
LIRA was published by Instituto de Ciencias Aplicadas y Technologia, based in Mexico, categorised as academia.
When was LIRA released?
LIRA was published in July 2004. 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 LIRA used for?
LIRA works in Vision, and is recorded as handling character recognition (OCR). Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
What GPU do I need to run LIRA?
None. LIRA 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.
