The 'gpt-prompt-engineer' is an AI tool available on GitHub, created by 'mshumer'. The tool aims to enhance the workload of data engineers working with Generative Pretrained Transformer models (GPT-models).

Its purpose is to automate and streamline the process of generating prompts that work well with GPT models. This is beneficial as it eliminates the manual task of trial-and-error in creating effective prompts, saving valuable time and resources.

The tool contains a number of files and notebooks like 'Instruct_Prompt > Base_Model_Prompt_Converter.ipynb', 'XL_to_XS_conversion.ipynb', 'claude_prompt_engineer.ipynb' and 'gpt_prompt_engineer.ipynb', which facilitate the prompt generation process.

The tool operates under MIT License providing users with the liberty to use, modify, and distribute the software. Through its public repository, it encourages wide community contribution towards its development.
