  "textContent": "Here is a simple Python example using a stop sequence with the OpenAI Responses API:\n\nfrom openai import OpenAI\n\nclient = OpenAI()\n\nresponse = client.responses.create(\nmodel=“gpt-4.1-mini”,\ninput=“Write a short bedtime story in two sentences. End the story with the marker .”,\nstop=[“END”]\n)\n\nprint(response.output_text)\n\nIn this example, `\"END\"` is the stop sequence. When the model generates `\"END\"`, the API stops producing more output, and the stop sequence itself is not included in `response.output_text`.",
