In experiment 1, Astra was given only the raw weights of four game networks (Breakout, Pong, Pac-Man, Freeway) with no hint of which games they were, and correctly named all of them.
In the MIT experiment, four tiny policy networks played grid-simplified versions of Breakout, Pong, Pac-Man and Freeway respectively; each network had 17,253 weights, and Astra got all four right, with confidence between 96% and 99%.
In the Pong-related tests, the run time exceeded one hour; on the Freeway task, Qwen simply failed.
In the game-identification experiment, Astra correctly identified all four small networks (Breakout, Pong, Pac-Man, Freeway) using only the raw weight-number text of each.
Simon Willison used a free Qwen model running on a laptop (27 billion parameters, file about 17GB) to reproduce the experiment of "identifying what game a small network is playing from its weights alone"; Qwen got three of four right (Pac-Man, Pong and Breakout), misjudged Freeway as a Pac-Man-like grid game, and each correct answer took from 46 minutes to over an hour.
Freeway is a 1981 Atari 2600 game and is noticeably less well known than the other three.
The games involved include River Raid, Freeway, Stampede, Donkey Kong, and Demon Attack, all titles born in the early 1980s.
