System Prompts Leaks
A continually updated archive of the verbatim system prompts behind widely used chatbots and coding agents, including releases from Anthropic, OpenAI, Google and xAI.
Entries record the full text of a system prompt alongside its model name and release date, spanning Claude's web, desktop and Claude Code system prompts across several model versions, ChatGPT and Codex, Gemini, Grok and other assistants; a running table tracks the most recently added or changed prompts.
The collection has been cited as a source by outside data journalism projects, including an interactive news story and a dashboard examining what a system prompt reveals about a conversation before it even starts. Contributions are accepted as pull requests when a different result is found for an already-listed prompt.
