Closed weights Stanford University 0.8K parameters June 1989

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.

What the numbers mean

What this model is

Truck backer-upper was published by Stanford University, in the country recorded as United States of America, during June 1989. The category the publisher falls under is academia.

It works in the domain of Driving, and is recorded as performing the task of self-driving car.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

How it was trained

The reason it appears in this catalogue at all: historical significance.

Answers

Truck backer-upper — common questions

01

Truck backer-upper— how many parameters does it have?

It has a parameter count of 0.8K. 6*25+25+8*45+45*6=805 (see Figure 6). 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.

02

Truck backer-upper— who created it?

It was published by Stanford University, based in United States of America, an organisation categorised as academia.

03

Truck backer-upper— when was it released?

It was published in June 1989. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

04

Truck backer-upper— what is it used for?

It works in the domain of Driving, and is recorded as handling the task of self-driving car. 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.

05

Truck backer-upper— 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.

06

Truck backer-upper— is it open source?

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

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.
