Andrej Karpathy’s ‘Lord of the Rings’ experiment shows how testing of AI models have changed and what they lack

Tech News News: AI researcher Andrej Karpathy, who joined Anthropic earlier this year, recently put Claude Opus 5 through a unique coding test, demonstrating how benc.

Claude Opus 5 pushes prompt-to-game AI from rough color blocks to full 3D prototypes with physics and music

Anthropic's Claude Opus 5 generates complete 3D games from single prompts, including a first-person shooter, a kart racer, and a Minecraft clone, all without a single external asset. Geometry, textures, physics, and in some cases music are produced as code and run directly in the browser. In side-by-side comparisons with GPT-5.6 Sol and Kimi K3, Opus 5 delivers significantly more detailed results. The article Claude Opus 5 pushes prompt-to-game …
