PewDiePie’s AI Model Beats GPT-4o: How He Fine-Tuned a Coding AI at Home

PewDiePie’s AI model scored 39% on the Aider Polyglot benchmark, outperforming GPT-4o (23.1%) and Gemini 2.0 Pro Exp (35.6%) on a coding test widely used in AI research. The retired YouTube star Felix Kjellberg spent months building a $41,000 home GPU rig, reading machine learning papers, and grinding through failed training runs to get there. He published the full journey in a video released on February 26, 2026. This is not PewDiePie casually asking ChatGPT to write code. He built a 10-GPU workstation, scraped GitHub for training data, generated synthetic datasets using the DeepSeek API, and fine-tuned Qwen 32B, a 32-billion-parameter open-source model. The result is a genuine AI fine-tuning […]

Nano Banana 2 Just Dropped: Google’s New Image Model Is Faster, Cheaper, and Reaches 4K

Google launched Nano Banana 2 on February 26, 2026, and it immediately replaced Nano Banana Pro as the default image generation model across the Gemini app, Google AI Mode, and Google Lens. The headline number: ~$0.067 per image, roughly 50% less than Nano Banana Pro’s $0.134 per image, at Flash-tier speed instead of the Pro model’s 20 to 60 second wait times. If you have been searching for “Nano Banana Pro 2,” this Nano Banana 2 review has the answers. Google officially calls the new model Nano Banana 2 (technically Gemini 3.1 Flash Image), not Pro 2, but the naming confusion is understandable. Here we cover what has actually changed, […]
