BASIC-L + Lion
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
Where it came from
BASIC-L + Lion was published by Google,University of California Los Angeles (UCLA), in the country recorded as United States of America, during February 2023. The publishing organisation is categorised as industry,Academia.
It works in the domain of Vision, and is recorded as performing the task of image classification.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
Training and provenance
The reason it appears in this catalogue at all: sOTA improvement.
Answers
BASIC-L + Lion — common questions
BASIC-L + Lion— what is it used for?
It works in the domain of Vision, and is recorded as handling the task of image classification. 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.
BASIC-L + Lion— what GPU do I need to run it?
None. This 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.
BASIC-L + Lion— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
BASIC-L + Lion— how many parameters does it have?
It has a parameter count of 3.1B. parameter count of original BASIC-L. 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.
BASIC-L + Lion— who created it?
It was published by Google,University of California Los Angeles (UCLA), based in United States of America, an organisation categorised as industry,Academia.
BASIC-L + Lion— when was it released?
It was published in February 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
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.
