About this paper
Anton Hristov
The paper tests whether rewriting a model’s earlier reasoning into a compact state record changes its later reasoning in tool-using tasks. A compressor rewrites prior assistant text before a pending tool result is revealed; both histories then receive the same result. Across accepted rewrites, 151 of 172 continuations used fewer reasoning tokens, but task-quality preservation was not established.
