Client Background
BlackHat Labs partnered with NextGen Coding Company to create an advanced, interactive platform that reimagined how fans engage with global artists. The centerpiece of the initiative was a 3D DJ Khaled chatbot, designed to replicate his personality, signature phrases, and larger-than-life energy.
The project’s goal was to combine AI-driven conversation, realistic voice synthesis, and 3D animation into a unified experience that fans could access instantly—without special hardware or downloads.
The Problem
BlackHat Labs required a conversational AI that could speak, think, and react like DJ Khaled in real time while scaling globally and maintaining low latency. The solution needed to integrate several key components:
ElevenLabs API for natural and expressive voice generation.
ChatGPT (GPT-4) for intelligent, context-aware conversations.
Nvidia Audio2Face for synchronized facial animation.
AWS Lambda, CloudFront, and Cognito for scalability, delivery speed, and security.
Additionally, the system had to comply with GDPR standards, support millions of interactions securely, and provide a consistent user experience across web and mobile platforms.
Our Solution
