Persistent Memory and Iterative Improvement in an LLM Agent for Chinese-Character Drawing

Does persistent memory accumulated from previous attempts help an LLM agent solve new problems, and does memory design affect that benefit?

Key points

  • We study programmatic Chinese-character drawing across five agent conditions attempting the same 668 items.
  • Accumulated memory produces modest aggregate gains despite substantial growth in the memory stores: free-form notes improve first-attempt success by 4.6 percentage points, while a design combining free-form memory with reusable code improves it by 2.8 points.
  • A separate post-hoc comparison finds a much larger improvement when the code-bank agent receives privileged, target-specific structural supervision.
  • These results suggest that memory design may affect where accumulated experience becomes useful, even when its average benefit is modest.
