System Prompts Leaks

System Prompts Leaks is a single repository of system prompts extracted from major AI models. The list includes Anthropic's Claude Fable 5, Opus 4.8 and Claude Code, along with OpenAI's ChatGPT 5.5. Prompts span a wide range of applications, from coding assistance to creative design, and the collection is updated on a regular basis. Its value is concentration: developers, researchers and anyone curious about how these systems are steered can read them side by side instead of hunting across separate platforms.
