A study found that advanced AI models can infer a neural network’s task from its raw weights and sometimes edit those weights. The author tested game-identification prompts and found that Qwen 3.8 27B on a laptop correctly recognized Pac-Man, Pong, and Breakout. The results are impressive, but the author says they don’t prove that code or human understanding is obsolete.
