Krafton uses its own large language model technology to generate 'unlimited' dynamic dialogue for non-player characters in its games, replacing a prior approach of paying human authors to write fixed game scripts. This was confirmed by Krafton's CFO in a 2024 earnings call.

Krafton's CFO stated in 2024 that 'instead of relying on the traditional method of paying authors to write game scripts, AI is being implemented to create infinite dialogue options and create more varied and interactive NPCs.' Krafton AI conducts 'full-cycle research on language models — covering pre-training, post-training, and fine-tuning' with the goal of developing game-specialized language model agents capable of 'comprehension, reasoning, decision-making, and emotional expression.' The resulting dialogue is combined with text-to-speech output for in-game delivery.
