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 […]

Haiku 4.5 on GitHub Copilot: Code Faster, Spend Less

Imagine your AI coding assistant responding the instant you finish typing. No more lag, no more waiting—just seamless, real-time help that feels like a natural extension of your thoughts. That’s the promise of Anthropic’s new Claude Haiku 4.5, now Generally Available (GA) in GitHub Copilot. It’s not just another update; it’s a fundamental shift in developer experience. Anthropic positions Claude Haiku 4.5 as delivering near-Sonnet 4 coding performance at one-third the price and more than twice the speed; a partner quote on Anthropic’s launch page cites ‘up to 4–5× faster than Sonnet 4.5.’ But is it powerful enough for your daily work? How much cheaper is it really inside Copilot? […]
