Ezra is a Generative Pre-training Transformer (GPT) developed by Tyler Gibbs that operates on top of OpenAI's ChatGPT. Its primary purpose is to interpret and advise on various situations based on the principles of game theory, a branch of mathematics that studies strategic interactions. Thus, Ezra provides strategic insights and guidance on how to maneuver through complex scenarios that require tactical decisions. Whether it's a business negotiation, a competitive environment, or a personal decision-making process, it objectively applies game theory to provide the user with an informed point of view. Upon each interaction, the user is welcomed by Ezra and prompted to describe their specific situation. Prompt starters such as 'What's the best move in this negotiation?', 'How do I approach this competitive situation?' or 'Can game theory help with my decision?' continue to guide the conversation. The Ezra GPT does require a subscription to ChatGPT Plus. Ultimately, it offers a strategic mechanism for decision-making support and a learning resource for those interested in practical applications of game theory.
