RedditPersona: A Modular Framework for Community-Conditioned LLM Adaptation from Reddit
RedditPersona is a modular system that standardizes creating AI models tailored to specific online communities using Reddit data. It collects posts, profiles users, applies five different methods to group users into communities, and then fine-tunes language models for each community. The results show that the choice of grouping method affects how well the resulting model reflects the community's behavior.
