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.

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.

Fine-tuning compute
2.8 × 10²⁰ FLOP

I think PaLM-540B wasn't actually involved in training and the authors trained a separate RL model. "The RL model is trained using 16 TPUv3 chips and for about 100 hours, as well as a pool of 3000 CPU workers to collect episodes and another 3000 CPU workers to compute target Q-values." Ignoring CPU calculations: 1600 hours * 3600 * 123 teraflops * 0.4 (assumed utilization) = 2.83e20

What the numbers mean

Background

PaLM-SayCan was published by Google, in the country recorded as United States of America, during August 2022. The category the publisher falls under is industry.

It works in the domain of Robotics, and is recorded as performing the task of robotic manipulation.

Its starting point was an existing base model, PaLM (540B). Most models at this scale are adapted from an existing base rather than built from nothing.

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

Answers

PaLM-SayCan — common questions

01

PaLM-SayCan— when was it released?

It was published in August 2022. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

02

PaLM-SayCan— what is it used for?

It works in the domain of Robotics, and is recorded as handling the task of robotic manipulation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

03

PaLM-SayCan— 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.

04

PaLM-SayCan— is it open source?

No. Its weights have not been published, so it exists only as a service controlled by its owner.

05

PaLM-SayCan— how many parameters does it have?

It has a parameter count of 540B. 540B from PaLM-540B. 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.

06

PaLM-SayCan— who created it?

It was published by Google, based in United States of America, an organisation categorised as industry.

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.
