NES CPU embedded in Qwen language model weights

By PulseAugur Editorial · [1 sources] ·

A project has successfully embedded a functional Nintendo Entertainment System (NES) CPU within the weights of a Qwen3.5 language model. This feat was achieved without any additional training, by compiling the NES CPU's logic directly into the model's parameters, with approximately 98% of the weights being zero. The model, when run, can execute NES instructions and produce outputs identical to a reference CPU, achieving a speed of around 193 tokens per second. AI

IMPACT Demonstrates a novel method for embedding computational logic within LLM weights, potentially impacting future model architectures and applications.
