NPCTalk mod brings real-time AI conversations to GTA V NPCs

The open-source NPCTalk toolkit by Universal Modder lets GTA V players speak into a microphone and get unscripted replies from NPCs in AI-cloned voices. Nemotron ASR handles recognition, Qwen 3.8 27B on Cerebras generates dialogue, and Fish Audio Drama 3 synthesizes speech on a cloud H100. A free playable mod is due next week.

• NPC responses take 1.15–2.2 seconds with push-to-talk
• Open-microphone detection adds about 0.7 seconds of latency
• Toolkit is MIT-licensed, but cloud services and GPUs cost money
• Currently works only in GTA V Legacy single-player
