  "account": "The recent paper Sparks of Weight-Space Programming revealed that large language models, such as GPT-6 Astra, can interpret and modify the raw weights of a machine learning model. Inspired by this, the author tested Qwen 3.8 27B on their laptop and found it capable of interpreting model weights as well. The paper presents the first question as: Can LLMs understand model behaviors from weights? To test this, weights from four neural networks trained to play simplified versions of classic computer games were fed to an LLM, which had to identify the original game without any tools or code execution. The author successfully ran this test using Kimi K3.1 Pro via OpenRouter and Qwen 3.8 27B on their laptop. Qwen accurately identified Breakout, Pong, and Pac-Man, but struggled with the Freeway game.",
