Meta is set to enhance Horizon Worlds by introducing AI-powered NPCs capable of real-time conversations, significantly boosting interactivity on the platform.

Building on previous updates, Meta will now roll out fully embodied conversational large language model NPCs, sourced from its latest Llama LLM, moving beyond the non-embodied AI help NPCs.

Creators will soon be able to customize NPCs with specific attributes such as names, backstories, personality traits, and dialogue styles, allowing them to serve as quest givers, guides, lore characters, shopkeepers, or reactive bosses.

These new NPCs will support dynamic, unscripted conversations with players, blending scripted dialogue with AI-generated responses and utilizing a variety of AI voices from a built-in library.

Meta plans to add more features later this year, including NPCs triggering in-world actions and more interactive experiences, with further details expected at Meta Connect on September 17th.

Earlier this month, Meta introduced new generative AI features for Horizon Worlds' desktop editor to simplify environment creation and lower the technical barriers for users building rich virtual experiences.

This initiative is part of Meta’s broader strategy to boost engagement in Horizon Worlds and differentiate it from competitors like Rec Room, Roblox, and VRChat, which currently rely on scripted NPCs.
