OpenAI releases GPT-5.5 prompting guide emphasizing outcome-oriented instructions over process-heavy prompts

AI要約

  • OpenAI published guidance on prompting GPT-5.5, recommending that prompts define the target outcome and constraints while allowing the model to choose its solution path, in contrast to older prompts that over-specified procedural steps.
  • GPT-5.5's default style is efficient and task-oriented; for conversational products, users should define both personality (tone, warmth, directness) and collaboration style (when to ask questions, how proactive to be) separately, keeping both blocks short.
  • For streaming applications where users notice delays before visible responses, prompts should instruct the model to emit a short preamble acknowledging the request and stating the first step before making tool calls or running multi-step agent workflows.
