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:

Agentic Workflows – how to guide multi-step reasoning and tool use

Chain of Thought – encouraging the model to reason step by step
Instruction Following – improving how the model interprets and responds to tasks
