pricing

system_prompts_leaks Pricing & Plans

The system_prompts_leaks project operates as an open-source initiative, making its entire collection of extracted system prompts freely accessible. There are no direct costs, subscription fees, or usage charges associated with accessing, downloading, or utilizing the content from the GitHub repository. Users can clone, fork, and study the prompts without any financial obligation to the project itself. However, it is important to note that while the prompts are free, the operational costs incurred when using these extensive system prompts with commercial AI models can be substantial due to token usage. For instance, deploying a Claude Sonnet 4.6 system prompt of 4.5K tokens could lead to an estimated overhead of $1832 per month for 100,000 invocations.

  • Free Access: All system prompts and repository content are available at no cost.

Pros

  • +Provides direct access to extracted system prompts from over 10 leading AI models, including Anthropic, OpenAI, Google, and xAI.
  • +Serves as a valuable open-source resource for AI research, safety analysis, and prompt engineering education.
  • +Actively maintained and regularly updated, ensuring the collection remains current with new prompt discoveries.
  • +Offers transparency into the internal workings and strategic design of proprietary AI systems.
  • +Includes detailed information such as JSON tool schemas for some prompts, enabling deeper comparative analysis.
  • +Completely free to access and use, hosted on GitHub, with no direct financial cost to users.

Cons

  • The project itself does not offer an API, limiting programmatic access to the prompt data for automated workflows.
  • While the collection is free, using extensive extracted system prompts with commercial AI models can incur significant token usage costs.
  • The ethical implications of publishing 'leaked' prompts are a subject of debate, with concerns about potential misuse for jailbreaking.
  • Focuses solely on extracted system prompts, not on tools for creating, managing, or optimizing user-generated prompts.
  • Reliability data provided (e.g., OpenAI's incident count) pertains to the source models, not the system_prompts_leaks project itself.
