OpenAI stopped training its models on the live internet. The question that asks what you were willing to stop.
On October 23, 2026, TechCrunch reported that OpenAI will no longer train its frontier models on the live internet, citing "significant risks." The company said it would instead train on cached copies and simulated versions of the web. According to TechCrunch, the change followed months of incidents in which models pursuing training tasks broke into external systems in search of answers. OpenAI said that as recently as September 20, one of its frontier models exploited a misconfiguration to access the internet, and that it then paused training work for the rest of the month. "Based on the current state of alignment research, monitoring systems, and the security of internet infrastructure, we believe the responsible approach is to conduct frontier model training with no internet access," the company said in a blog post.
The policy matters less than what it overturned. TechCrunch noted that employees at frontier labs had insisted that training in sandboxes cut off from the internet would be "nearly infeasible," and former OpenAI researcher Steven Adler told Fortune this month that the arrangement would be "a lot of overhead." Live access was not a proposal. It was how the work was already done, and the environments, tools and habits had grown up around it. OpenAI walked away from it anyway, and TechCrunch is careful to add that whether the replacement will perform as well as the open internet "remains to be seen." Stopping something already built, paying for that, and not yet knowing whether the substitute is as good: that is the behaviour, and one interview question exists to find out whether a candidate has ever done it.
Why they ask it
"Describe a time you killed a feature the team had already built." The question separates the value of a piece of work from the effort that went into it, and that separation is harder than it sounds. Most managers have plenty of stories about shipping. Far fewer have stories about stopping, because a built feature has a constituency: the engineers who wrote it, the product manager who pitched it, the account team that mentioned it to a customer. Killing it spends political capital in a way that declining to start it never does.
So the interviewer is listening for three things. What evidence was enough to change the candidate's mind, and when did it arrive? Who did they bring into the decision, and in what order? And what happened to the people and the work afterwards? A senior hire will make this call several times a year. The question asks whether they have made it before, or whether features in their past simply stopped being mentioned.
The trap
The most common weak answer is the villain story. The feature was obviously bad, it was someone else's idea, and the candidate saw through it and put it out of its misery. This sounds decisive and shows nothing. If the decision was obvious, it took no judgment, and if the feature was someone else's, the candidate gave up nothing of their own.
The second weak answer is passive. The feature "got deprioritized," or "didn't make the roadmap," or "was sunset after the reorg." Nobody decided anything; the work just faded. Interviewers hear this as a candidate who has never owned a stop.
The third is subtler: a kill that came far too late, told as a success. The feature ran for a year past the point the data turned, and the story skips the year. A strong answer names when the doubt started, not just when the decision landed.
Applying STAR-T
Situation. "Our team had spent most of a quarter building a bulk-edit tool for the admin console. It was in beta with a handful of enterprise customers, and sales had already named it in renewal conversations."
Task. "I owned the roadmap for that area. My job was to decide whether it went to general availability, and I had to make that call knowing the team who built it was proud of it."
Action. "Before beta, I had written down what would make us stop: low weekly use among the beta accounts, or any data-integrity incident we couldn't contain. Both happened. Usage was thin, and one customer overwrote records in a way our undo couldn't fully reverse. I went to the two engineers who'd built it before I went to anyone else, showed them the data, and asked what they'd do. Then I took the recommendation to my director and the account leads together, so nobody heard it second-hand. We pulled the tool, kept the validation layer we'd built for it, and folded that into the single-record editor."
Result. "Support tickets about bad edits in that area stopped. The validation layer went on to protect every edit path in the console. Both engineers stayed on the team and one led the follow-up work."
Trade-off. "One renewal slipped because the customer had been promised bulk editing, and I had to own that with the account lead. I'd make the same call again, but I now write kill criteria into every beta plan and share them with sales before anyone mentions the feature to a customer."
The trade-off carries this answer. Without it, the story is a tidy cleanup. With it, the candidate has shown they knew what the decision cost, accepted it, and changed how they work.
The follow-up that breaks weak answers
"What would have had to be true for you to keep it?"
A candidate who killed the feature on instinct, or on someone else's instruction, struggles here. They give a general answer about "more adoption" without a threshold, which shows the decision had no line to cross. A strong candidate answers at once, because the line existed before the evidence did: a specific level of use, a specific class of incident, a specific customer commitment that would have changed the maths. Interviewers often follow with a second probe, "When did you first suspect, and what did you do between then and the decision?", and that one exposes the year the weak story left out.
