You can now ask ChatGPT follow-up questions in the same conversation

Add up to 4 follow-up questions to a ChatGPT task and get each answer from the same conversation, with its own sources and search queries.

What you get

• payload.followUps: up to 4 more questions after the first answer, asked in the same ChatGPT conversation.
• followUps in the response: one answer per follow-up, in order. Each item has the prompt that was sent and that answer’s text, markdown, sources, searchQueries and model.
• select: press the button on a form ChatGPT shows in an answer, such as a budget or use picker, and get the narrowed answer. selection records the button and the values chosen.
• The top-level fields stay the first answer, so the code that reads them today keeps working.

How it works

Each follow-up is asked in the conversation the first answer started, so ChatGPT answers it with the earlier turns in view. In the example below, ChatGPT first recommended HubSpot, Pipedrive and Attio for a 10-person startup. Asked “Which of those has a free plan?”, it answered with a free-plan table for HubSpot, Attio, Zoho CRM, Pipedrive and Close, and the third turn compared HubSpot and Attio on price per seat.

When an answer ends with a form, ChatGPT asks the user to pick options and press a button. In Korea, the question “가성비 무선 이어폰 3개 추천해줘” (recommend 3 good-value wireless earbuds) came back with a form for smartphone, budget and use. { "select": {} } pressed its button “조건에 맞춰 다시 추천받기” with the options ChatGPT had preselected (Galaxy, ₩50,000 or less, commuting and music) and returned a new recommendation for them.

button counts the buttons of the previous answer from 0 and defaults to 0. choices sets the options, as an array in the form’s order or as an object keyed by each choice’s name in layout. Each value is an option’s value, its label or its position from 0. When the previous answer lacks the form, button or option, the remaining follow-ups stop, followUpsStopped gives the reason, and the task completes with the answers it received.

Every turn gets the same checks as the first answer: an empty reply, the requested location and the model. A turn that fails a check is asked again at the same point in the conversation, like ChatGPT’s Regenerate. A five-turn conversation in Korea finished in 240 to 285 seconds.

Where it helps

• Follow a buyer past the first answer: ask which option is cheapest or has a free plan, and see which brands stay in the answer.
• Press the budget and use forms ChatGPT shows in shopping answers, and measure the narrowed picks for each choice.
• Ask ChatGPT to compare your brand with a competitor it named in the first answer, and read the sources it searched to compare them.
