Claude's 120,000-character system prompt leaked online. Nick Perry explains how you can copy it into cheaper models like GLM 5.2 or KIMI K2 to make them perform like Claude, with a link to the GitHub repository.
Claude Fable 5, it just came back and somebody's already leaked the entire system prompt on the internet. Here's why this is so important for you right now. See, this isn't some basic prompt. It's 120,000 characters long, over 1,500 lines, and it covers the exact set of instructions Anthropic uses to control how their most powerful model thinks, plans, and does work. And the best part is, you can take these exact instructions and inject them into cheaper free models like GLM 5.2 or KIMI K2 to follow the same playbook that Claude does, which significantly improves results and allows you to get the best of both worlds. And if you want it for yourself, then check it out on this GitHub repo.
