PewDiePie goes all-in on self-hosting AI using modded GPUs, with plans to build his own model soon — YouTuber pits multiple chatbots against each other to find the best answers

PewDiePie using Qwen to add deep research to itself.

PewDiePie has built a custom web UI for self-hosting AI models called "ChatOS" that runs on his custom PC with 2x RTX 4000 Ada cards, along with 8x modded RTX 4090s with 48 GB of VRAM. Running open-source models from Baidu and OpenAI, PewDiePie made a "council" of bots that voted on the best responses, and then built "The Swarm" for data collection that will become the foundation of his own model coming next month.

Once the poster boy for gaming on YouTube, he has settled into a semi-retired life in Japan with his wife, Marzia. While he no longer uploads as frequently, and his content has shifted from exaggerated, reaction-channel-style videos to more family vlogs, it seems his love for computing has reemerged. Felix was never known to be particularly tech-savvy, but he's gone on a crazy arc as of late — de-Googling his life, building his first gaming PC, and learning how to write code. His latest act is one of decentralization: self-hosting AI models and eventually building his own.
