This GitHub repository, "system-prompts-and-models-of-ai-tools" by x1xhlol, is a comprehensive collection of system prompts and underlying model information for a vast array of popular and emerging AI tools. It’s essentially a curated database designed to help users understand *how* these tools are instructed to behave and, crucially, how to craft better prompts to achieve desired results. The repository isn’t focused on building new AI tools, but rather on reverse-engineering and documenting the internal workings – specifically the system prompts – of existing ones. This is incredibly valuable because system prompts are the foundational instructions that dictate an AI’s personality, style, and capabilities.

The core of the repository is organized around individual AI tools like ChatGPT, Bard, Claude, Perplexity AI, and many others, including image generation models like Midjourney and Stable Diffusion. For each tool, the repository attempts to reconstruct the system prompt used by the developers. These aren’t official disclosures (in most cases), but rather educated guesses based on extensive testing, observation of the AI’s behavior, and analysis of publicly available information. Alongside the reconstructed system prompt, the repository also details the model architecture used by the AI (e.g., GPT-4, Gemini Pro), its training data cutoff date (when its knowledge base was last updated), and other relevant technical specifications. This provides a holistic view of the tool beyond just its user interface.

The value proposition is significant for several reasons. Firstly, understanding the system prompt allows users to tailor their own prompts more effectively. Knowing the inherent biases or constraints built into the AI can help avoid frustrating interactions and unlock more nuanced responses. Secondly, the repository serves as a valuable resource for researchers and developers interested in AI alignment and safety. By examining these prompts, they can gain insights into how AI behavior is shaped and identify potential risks. Thirdly, it’s a fantastic learning tool for anyone wanting to understand the underlying mechanics of large language models (LLMs) and how prompt engineering works in practice.

The repository isn’t static; it’s constantly being updated as new AI tools emerge and existing ones are refined. The community is encouraged to contribute, submitting their own reconstructed system prompts and model information for review. The quality of the prompts varies – some are highly confident reconstructions, while others are more speculative – and the repository clearly indicates the confidence level for each entry. It also includes a section on "Prompt Engineering Techniques" offering general advice on crafting effective prompts, beyond just understanding the system prompts of specific tools.

Finally, the repository includes a disclaimer emphasizing that the provided system prompts are *approximations* and may not be entirely accurate. AI developers frequently update their models and system prompts, so the information is subject to change. However, even as approximations, these reconstructed prompts offer a powerful window into the inner workings of some of the most influential AI tools available today, making this repository a crucial resource for anyone working with or studying artificial intelligence.
