Paper proposes content-based addressing to replace positional rotation in long-context attention

A new arXiv preprint argues that rotary position embeddings (RoPE) degrade as context windows grow, because the integer positions seen during inference differ from those used in training. The authors suggest determining attention rotation from content-based addressing rather than from a token's fixed index, aiming to remove this train-test mismatch. The work is a methodological proposal and cross-listing revision, not a released model or product.

Paper Derives Exact Finite Attention Responses from RoPE Derivatives

A research paper presents a method for computing exact local responses to attention interventions in transformer models. Using the derivative of rotary position embeddings, candidate edits can be scored from a cached baseline plus a single backward pass, avoiding full recomputation. The approach aims to make attention-level analysis and editing more computationally efficient.
