Details
Krafton AI researches and develops TTS systems capable of generating emotionally expressive speech from text, as well as voice conversion technology that transforms one person's voice into another. The company's CFO stated that TTS 'generates voice recordings that best fit the characteristics of the game without having voice actors do a voiceover.' Krafton also uses LLM capabilities to generate 'unlimited conversations' for NPCs, combining language model outputs with TTS to produce in-game dialogue audio. Krafton has also open-sourced speech AI models (Raon-OpenTTS and Raon-Speech) on GitHub.

The feature was included as an experimental option at inZOI's early access launch in March 2025.Creative GenKrafton offers players in inZOI the ability to generate custom clothing textures from text prompts and convert 2D images into 3D in-game objects using on-device generative AI tools. These features have been available since inZOI's early access launch in March 2025.OtherKrafton tested an AI teammate called 'PUBG Ally' inside PUBG: Battlegrounds, which players can squad up with in Arcade Mode; the AI communicates by voice, adapts strategies in real time, fetches items, and assists with revives. Public playtesting in PUBG: Battlegrounds Arcade Mode began in early 2026.
