Abstract
Online platforms increasingly host hate speechtargeting marginalized communities, includ-ing homophobic and transphobic commentsdirected at LGBTQ+ individuals. Counter-narratives provide a constructive way to re-spond to harmful speech by promoting em-pathy, factual clarification, and respectful di-alogue.In this work, we participate in the Shared Taskon Counter-Narrative Generation on Homopho-bic and Transphobic Comments at LT-EDI @ACL 2026. We adopt a zero-shot promptingapproach using large language models accessedthrough publicly available AI tools, includingGPT-4o, Gemini 1.5 Pro, and Llama-3 SonarLarge via Perplexity AI. Instead of traininga task-specific model, we design a structuredprompt that guides the models to generate re-spectful, concise, and contextually appropriatecounter-narratives.Experiments were conducted on English andTamil comments provided by the organiz-ers. Results demonstrate that prompt-basedgeneration can produce meaningful multilin-gual counter-narratives without additional train-ing. Our approach highlights the potential oflarge language models as lightweight tools forcounter-speech generation in multilingual on-line environments.
