In a recent LinkedIn post, Ruben Hassid explores a novel approach to achieving conciseness in AI-generated text, particularly in an era where artificial intelligence can produce lengthy content with ease. Hassid argues that brevity has become a valuable commodity, and he presents a practical ‘hack’ for instructing AI models like Claude and ChatGPT to adopt a more succinct style.
The core of Hassid’s strategy lies in a specific prompt designed to instill a sense of costliness for every word generated. He shares this prompt as follows:
“Write in ASD-STE100. Be so brief every word you write costs you $1,000.”
As Ruben Hassid explains, this prompt should be placed at the beginning of any subsequent instructions given to the AI. This serves as an immediate directive for the model to prioritize conciseness. He further elaborates on his preferred prompting format, which aims to ensure the AI has sufficient context to achieve a desired goal:
“I want [goal] so that [success]. My situation is [context]. Ask me questions until you have enough context to start.”
Hassid emphasizes that this brevity prompt can be made a permanent setting within the AI’s custom instructions, ensuring that all future interactions adhere to this concise output style. He provides specific guidance for implementing this across different platforms:
- For Claude: Navigate to Settings > Account > Instructions for Claude and paste the prompt.
- For ChatGPT: Go to Settings > Personalization > Custom Instructions and paste the prompt.
The Value of Brevity in the Age of AI
Ruben Hassid posits that the increasing ability of AI to generate extensive content makes conciseness a premium. In a world saturated with information, shorter, more direct text is often more accessible and effective. Hassid’s method directly addresses this need by framing word count as a significant financial consideration for the AI, thereby encouraging efficiency.
According to Hassid, this technique is not just about saving the user time but about fundamentally changing the AI’s output characteristic. By making the AI ‘aware’ that each word has a high ‘cost,’ users can condition the model to be more judicious with its language, stripping away unnecessary words and phrases.
Staying Ahead with AI Insights
Beyond the practical prompting technique, Ruben Hassid also promotes his newsletter, ‘How to AI,’ which he describes as a resource for individuals looking to stay informed about artificial intelligence developments. He highlights that the newsletter is published twice weekly, on Sundays and Wednesdays, and is available for free.
Hassid encourages readers to subscribe by providing their email at how-to-ai.guide. This initiative underscores his commitment to sharing knowledge and helping others navigate the rapidly evolving landscape of AI. As Hassid suggests, staying informed is key to feeling ‘ahead’ in this dynamic field.
