When Can LLM Reasoning Reliably Reuse Intermediate Results?

Sampling complete solutions gives large language models more chances to solve a problem, but each attempt starts again.

Key points

  • For tasks with several subproblems, all required answers must be correct in the same attempt.
  • Retaining intermediate results can avoid repeating correct work, but errors in those results may affect later attempts.
  • Experiments across eight reasoning models examine composite mathematics and arithmetic.
  • Across four DeepSeek models, average success on the second subproblem is 36.2 percent without first-subproblem context, 57.2 percent with its answer, and 58.3 percent with its reasoning and answer.
