OpenAI’s New GPT-5.6 Prompting Guide Says Simpler Prompts Work Better

OpenAI has released updated prompting guidance for GPT-5.6 that encourages users to keep prompts simple. Rather than relying on long XML blocks, persistence scripts, or heavily structured instructions, the guide recommends stating the destination clearly, defining the stopping conditions, and then letting the model do the work.

The update matters because prompting has become a core skill for people and companies using AI tools in workflows, product development, and content generation. For readers following the broader tech and crypto ecosystem, it is another sign that model behavior is becoming more guided by clear objective-setting than by overly complex prompt engineering.

According to the source material, the guidance is framed as a shift in how users should think about working with ChatGPT-style models. Instead of trying to micromanage every step, OpenAI is steering users toward concise instructions that define the task and the end point.

That approach may simplify adoption for both casual users and teams building with AI, especially as prompt design has often been treated like a specialized craft. The new guidance suggests that, at least in OpenAI’s view, better results may come from clarity and restraint rather than added complexity.
