Dev says Claude-family models wrote nearly all the code, including the Rust engine

Developer adonissingh describes a project where models wrote almost all the code — mainly Opus-5.5 (previously Fable-5.1), including the Rust engine — while he only flagged what felt wrong, stated ambitions, and pushed hard on execution. The launch video was produced by Fable-5.2 coordinating Opus-5.5 subagents, with music generated in Csound.
Other features include a resolution slider up to 10x; 10 ways to connect a model (API keys via OpenRouter, OpenAI, Anthropic, Google, Groq, QwenCloud, Cursor — or your Claude/ChatGPT plan through Claude Code and Codex); builds can be shared as flyable web pages or exported as .schem files / full Minecraft worlds.
