X - Teaming Evolutionary M2S is a framework that automatically discovers and optimizes multi-turn-to-single-turn (M2S) templates through language model-based evolution. It performs smart sampling from 12 sources and maintains a complete audit log by leveraging LLM-as-judge, inspired by StrongREJECT. Setting a success threshold of $\theta = 0.70$, we obtained two new template families through five generations of evolution, achieving an overall success rate of 44.8% (103/230) on GPT-4.1. Furthermore, we observed that structural improvements varied across models, and that there was a positive correlation between prompt length and scores.
