Gemini 3 Coded a 3D Game From ONE Prompt
In this week’s video, I’m putting the most powerful AI coding tools head to head in an epic showdown. I test OpenAI’s newly updated Codex 5.1 against Claude Code’s powerful sub agent system to see which can build a better Minecraft style wizard game. The real shock, however, came from what appears to be Gemini 3, which generated a surprisingly detailed 3D world right on my phone from a single prompt. Before diving into the code, I also showcase Gemini’s incredible new real time voice capabilities, getting it to switch accents on the fly, teach me Greek, and even guess where I’m from.
