OpenAI Official GPT-4.1 Prompting Guide 📝 OpenAI just released their official GPT-4.1 Prompting Guide. Thanks to Andreas Horn for sharing this on LinkedIn. I also created a custom GPT for my community to use, so if you dont feel like reading the whole thing you can use this GPT: Prompt Boss It outlines how to write more effective prompts and provides examples for a range of advanced use cases. Worth reading through if you're building AI workflows or trying to improve how GPT-4.1 handles instructions. The main sections are: 1. Agentic Workflows – how to guide multi-step reasoning and tool use 2. Long Context – strategies for using GPT-4.1’s extended context window effectively 3. Chain of Thought – encouraging the model to reason step by step 4. Instruction Following – improving how the model interprets and responds to tasks 5. General Prompting Advice – formatting, placement of instructions, and token management Let me know what you think, I am interested in how others are applying this in real workflows.
