FOD Fable 5 just came back and somebody's already leaked the entire system prompt on the internet. And 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 gets things done. And the best part is you can take these exact

instructions and inject them into cheaper open source models like GLM 5.2 or Kimi Cave 2.7. So they follow the same playbook that Anthropic built for the world's best AI model. This significantly improves results and allows you to get the best of both worlds. Want it for yourself? Just comment Fable and I'll send you guys the link directly.
