PewDiePie reveals his own AI platform after issuing urgent warning to subscribers
PewDiePie reveals his own AI platform after issuing an urgent warning to subscribers.
Felix 'PewDiePie' Kjellberg, once the undisputed king of YouTube with the platform's most-subscribed channel for years, has surprised fans again. This time with an ambitious tech project that shows just how far he's evolved since his gaming days.
The internet megastar dominated YouTube throughout the 2010s with his gaming streams, memes and reaction videos. At his peak, he had over 100 million subscribers and was essentially the face of YouTube, before being overtaken by the likes of T-Series and MrBeast.
Since stepping back from his YouTube days, Felix has built a completely different life. Now living in Japan with his wife Marzia and their son, he spends more time on his personal hobbies and interests.

Recently, Felix has been continuing to explore the world of open-source tech with his custom-built AI chatbot.
The YouTuber has unveiled a fully self-hosted AI interface that runs entirely on his own PC, powered by an impressive 10-GPU setup and a team of chatbots that literally debate and vote on the best response to queries.
On 31 October, he showed off the project in his new video titled: “STOP. Using AI Right now.” In the video, he showed off his powerful new computer setup, worth around $20,000, built with several RTX 4090 GPUs.
He explained how he added features like search functionality, memory, RAG (Retrieval-Augmented Generation), and audio output to create his own ChatGPT-style user interface.
At one point, Felix joked about 'bifurcating' PCIe lanes to fit more GPUs, experimenting with 70B, 120B, and even Qwen 245B models through vLLM.
The YouTuber says he wanted to 'max out' his rig's capabilities and ended up running local AI at speeds that rival major commercial tools like OpenAI's ChatGPT.
Instead of creating his AI from scratch, Felix explained that he used his computer to self-host existing open-source AI models.
Specifically, he ran OpenAI's open-source GPT-OSS 120B model, which contains 120 billion parameters. He also created what he calls a 'council' of AI agents, which debate and vote on the best answer to his queries. Proud of his setup, the internet personality said it felt 'exactly like ChatGPT, but much faster.'
But he's not ready to stop there.
Felix plans to fine-tune his model next month. Furthermore, he revealed he’s donating idle GPU power to Folding@home under Team Pewds (1066966) to support disease research.
It's a far cry from the high-energy gaming videos that made him famous over a decade ago, but his audience remains just as curious about his new direction.
