Developer finds smaller 27B parameter model outperforms GPT-4 class 405B model at creating immersive tabletop RPG narratives

Creator built an open-source, model-agnostic tabletop GM tool designed to run D&D sessions on various LLMs with tool support capabilities

Tested 8 different language models using a custom 'narrative quality probe' to evaluate atmospheric storytelling rather than just tool-call compliance

A 27-billion parameter model demonstrated superior narrative quality compared to a 405-billion parameter model, suggesting size doesn't guarantee better creative writing

The tool successfully introduced the creator's family to fantasy RPGs, proving practical value despite criticism from D&D purists about AI integration
