Universal Modder's NPCTalk open-source toolkit has been published on GitHub, using models such as Nemotron ASR, Qwen 3.8 27B, and Fish Audio Drama 3 to enable real-time, unscripted voice conversations and animated reactions for GTA 5 NPCs. It is currently demonstrated only in the legacy single-player mode, with a free-to-play mod set to arrive in the week starting October 26, 2026.
