YouTube sensation Felix “PewDiePie” Kjelberg has recently shifted gears towards a semi-retired family-focused life in Japan. This lifestyle change has sparked a new interest in technology for Felix, with his latest uploads showcasing his exploration of Linux, computer building, and dabbling in AI.
In a video titled “STOP. Using AI Right now.” uploaded on October 31, 2025, PewDiePie introduced his audience to his initiative to maximize his computer’s capabilities for cancer research. He shared his involvement in the Folding@home project, where users contribute their GPU power to assist scientists in protein simulations for disease research. This collaborative effort aims to create the world’s largest supercomputer for a noble cause.
With a powerhouse PC equipped with GTX 4090 GPUs, Felix also ventured into self-hosting AI models. He hosted OpenAI’s “GPT-OSS 120B” model on his computer, leveraging its massive parameter capacity of 120 billion. The seamless user experience and speed of the AI model left PewDiePie impressed, prompting him to upgrade his computing power to run the “Qwen 2.5 3B” model.
In his video, PewDiePie emphasized the importance of self-hosting AI models to safeguard personal user data from large corporations like OpenAI or Google. He shared his reservations about artificial image and video generation, particularly due to his newfound interest in drawing and art. Additionally, he expressed frustration over the oversaturation of AI in the market, labeling it as the latest buzzword that has lost its essence.
While acknowledging the backlash against AI usage, PewDiePie also criticized those who vehemently oppose artificial intelligence. He cited an incident involving fellow YouTuber Markiplier, who faced criticism for utilizing AI in his Cloak clothing brand. Despite these controversies, PewDiePie remains focused on exploring the potential of AI while advocating for responsible usage.
In response to fans noticing his absence from YouTube’s top 10 most-subscribed channels, supporters lauded PewDiePie for his successful career and transition to a more personal and purposeful lifestyle in Japan. As Felix continues to delve into the realms of technology and AI, his audience eagerly anticipates his future endeavors in the ever-evolving digital landscape.
