CopyLoop: Fast Looped Transformer Decoding via Context Copying and Shallow Screening

Wenyu Du, Stephen Chung

Speeds up looped language models by copying candidate token spans from the context, screening them at a shallow depth, and verifying them through the remaining loops. Overlaps verification with new proposals and evaluates the approach on code and mathematical reasoning.
