AI Has Go Rating of Over 5100 Versus Best Human at 3696

In 2018, OpenAI discovered that the amount of compute used for AI training doubles every 3.5 months. By comparison, the number of transistors per square inch on integrated circuits only doubles every 18 months, a.k.a Moore’s Law.

The best human has a GO rating of 3695 while Alpha GO Zero has an ELO rating of 5185. Human players were beaten 100 to 0 and AI GO systems can only crush the prior best AI to show improvement.

The hardware cost for a single AlphaGo Zero system, including custom components, is estimated to be $25 million.

There has been an open-source implementation of Alpha Go Zero. ELF OpenGo is the first open-source Go AI to convincingly demonstrate superhuman performance with a perfect (20:0) record against global top professionals.

  1. No, ratings only take into account the result of games (win, loss, draw) and the strength of the two players. Sounds circular, but it isn’t. Elo is relative. You can only say how much stronger one person is from another. You could give 5000 more Elo to everyone and it would make no difference to the system. The level is not an absolute measure of strength.
    When you look at that table it gives an expected % result. If you are 200 Elo stronger than an opponent, and you play many games with them, you would be expected to get roughly 3/4 of the game points (1 point for win, 1/2 point for draw, 0 points for loss). Don’t confuse these points for the others though. You generally get a lot more than 1 Elo point for a win. If you draw someone stronger you get Elo points also.
    Your rating is adjusted after every tournament/match based on how many game points you got and the level of the opposition you faced. Here is a calculator:
    There is also a K value that allows more movement when you have not played many games yet (provisionally rated) or are a kid and thus are expected in increase in strength more rapidly than the system would normally be able keep up with.

  2. Not sure what this table represents. Can it be said that a human “Go rating” is simply the score a human can achieve in a Go game?
