Pillar Specification & Hub DirectoryOpenAI Custom Instructions & System Prompts
Targeted system instructions for ChatGPT, GPT-4o, and o-series reasoning models.
prompts/openai-custom-instructions.mdHow OpenAI Custom Instructions Operates in Production
OpenAI system instructions set the foundation for model behavior, response formatting, and technical boundaries. Crafting concise, role-anchored instructions with negative constraints produces higher-fidelity code and prevents verbose boilerplate.
Set the engineer role, technical boundaries, and brevity requirements to avoid chatty responses.
