A community-maintained repository on GitHub that catalogs extracted system prompts from every major AI chatbot has added its latest batch of captures — and at 216 stars per day, it has become one of the most-watched transparency projects in the AI ecosystem.
The system_prompts_leaks repository, maintained by developer asgeirtj, now contains verbatim system prompts from Anthropic, OpenAI, Google, xAI, Meta, Mistral, and dozens of smaller AI products. The most recent additions include Claude Fable 5.1 (Anthropic's latest), Codex GPT-6-Astra (OpenAI's code agent), and Grok 4.6 (xAI's flagship).
What distinguishes this project from casual prompt-sharing is its rigor and breadth. The repository has been cited by The Washington Post for its interactive investigation into AI system rules, and by CEPS's AI World dashboard for tracking how system prompts evolve over time. Each capture is dated, versioned, and cross-referenced across products — making it a living record of how AI companies encode safety policies, personality instructions, and operational constraints.
The repository covers the full landscape: Claude.ai's web and mobile prompts, Claude Code's developer-oriented instructions, ChatGPT's personality modes and voice configurations, Gemini's family of prompts across Flash and Pro variants, and Grok's rapidly evolving lineup. It also captures prompts from smaller products like Cursor, Perplexity, Notion AI, and various coding assistants.
For developers and researchers, the value lies in the comparisons. Watching how a company's system prompt changes between model versions reveals shifting priorities — when a safety constraint is added, when a feature is quietly removed, or when the model's personality instructions are rewritten. The repository's growing table of additions provides a chronological audit trail that no single company publishes.
The project operates in a gray area: AI companies generally consider system prompts proprietary, though they are transmitted to users' browsers with every API call. The repository's maintainer argues this makes them public by nature, and the growing community of contributors appears to agree — the repository regularly appears in GitHub Trending and continues to attract pull requests from users who extract prompts from new products.
