In light of the rapid improvement in generative AI capabilities, we are considering introducing the following two participation divisions for long-term AtCoder Heuristic Contests so that more participants can enjoy the contests. #### human only division A division in which generative AI may not be used for contest participation, except for limited uses such as code completion and translation of the problem statement. #### with AI division A division in which generative AI may be used to consider solution approaches, generate or modify code, analyze execution results, and perform other related tasks. To understand the demand for each division, participants’ preferred formats of participation, and how the boundaries of future generative AI usage rules should be defined, we are conducting a survey on the following page. We would greatly appreciate your response. https://atcoder.jp/contests/ahc-survey2026
