Lorem Perturbation Technique Improves LLM Math Reasoning in GRPO Training

Short summary

Lorem Perturbation (LoPE) improves LLM math reasoning by prepending random Lorem Ipsum text before hard problems during reinforcement learning, exploiting how nonsense prefixes nudge stuck models down different reasoning paths. This simple, near-zero-cost method solved 50 questions standard GRPO approaches failed on entirely, with 2.1x–5.0x advantage amplification on successful attempts. Immediately applicable; no architecture changes needed.

• •LoPE prepends Lorem Ipsum text during RL training to perturb reasoning and unlock novel solution paths
• •50 previously unsolvable questions cracked; +4.6 pts average on math benchmarks
• •Zero-cost experiment for any GRPO fine-tuning setup—no architecture changes required
