Answers

Deep Blue — common questions

01

Deep Blue— when was it released?

It was published in May 1997. 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

Deep Blue— what is it used for?

It works in the domain of Games, and is recorded as handling the task of chess. 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.

03

Deep Blue— 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

Deep Blue— is it open source?

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

05

Deep Blue— how many parameters does it have?

It has a parameter count of 8K. "The new chess chip had a completely redesigned evaluation function, going from around 6400 features to over 8000". 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

Deep Blue— who created it?

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