Researchers have developed a new method for cryptanalytically extracting bias-free Gated Linear Unit (GLU) feed-forward blocks from language models. This technique, which uses finite-difference curvature and paired observations, can recover these specific block types that were previously inaccessible to extraction methods. While successful in recovering isolated blocks from models like Qwen, Llama, and Gemma with sub-percent median validation error in high-precision tests, the method does not yet solve the challenge of deriving the necessary internal block responses from final model outputs.
