Research questions LLM poetry planning vs. improvisation

A new research paper investigates whether large language models like Claude 3.5 Haiku exhibit genuine planning capabilities when generating poetry, or if their apparent foresight is merely improvisation. The study tested seven configurations of open models (ranging from 0.6B to 2.6B parameters) with six open cross-layer transcoders (CLTs). While the research found that models could generalize positional awareness, it failed to recover evidence of rhyme anticipation at the newline before a line is written, suggesting that at this scale and with these transcoders, the causal site for such behavior is emission-adjacent rather than a distinct planning phase.

    Planning or Improvisation? Stress-Testing the Poetry Planning Site on Open Models and Open Cross-Layer Transcoders

    arXiv:2609.18440v1 Announce Type: new Abstract: Lindsey et al. (2025) report that Claude 3.5 Haiku plans rhymes: features for candidate rhyme words are active on the newline before a line is written, and a suppress-and-inject intervention redirects the line only when applied ther…
