SkyrimNet mod enables LLM-powered NPC roleplay in Skyrim

A user details how the SkyrimNet mod integrates large language models into The Elder Scrolls V: Skyrim to create dynamic, emergent storytelling through AI-controlled NPCs. By utilizing open-weight models like Google Gemma 4 31B and Deepseek V3.2 via OpenRouter, the mod allows players to generate custom questlines and character interactions in real-time.

• SkyrimNet replaces static NPC dialogue with LLM-generated responses, enabling complex roleplay scenarios such as merging distinct personalities within a single character.
• The system relies on external services like OpenRouter for inference, as running models like Deepseek V3.2 locally requires excessive compute resources.
• Users must manually inject context and actions into prompts to guide the AI, as the model defaults to generic storytelling without direct input.

The technology offers a solution to static mod content by allowing players to craft unique narratives, though it currently demands significant technical setup and a tinkerer's mindset.
