Have you ever noticed how your AI assistant suddenly goes mute during Gaokao? No homework help, no essay generation, no photo-based problem solving. It’s not a glitch — it’s a carefully timed lockdown. And it’s been going on for years.
This isn’t just about preventing cheating today. It’s the latest chapter in a decades-long tug-of-war between those who want to exploit technology and those who defend a level playing field. Let’s trace the evolution — from pagers to drones to large language models — and see what it really reveals about fairness.
Back in the 1990s, a pager on your belt was a status symbol. But soon, students used pagers to receive exam answers via operators. School rules quickly banned them. Then came mobile phones, and the ban expanded. By 2011, metal detectors appeared at exam halls. A few years later, radio monitoring vans and "cheating detector" gadgets became standard — some could even pick up wireless earbuds from across the room.
In 2015, a drone named "Cheat Buster" patrolled exam sites in Luoyang, scanning radio signals from 500 meters up. The irony? The same technology that enabled cheating was now used to catch cheaters. It felt like a sci-fi movie.
Then AI arrived. At first, it was too weak to pose a real threat — media even tested if AI could pass Gaokao. But by 2024, models like Qwen, Doubao, and Kimi became powerful enough to answer exam questions accurately. That’s when regulators stepped in. In April 2025, five government departments jointly issued a plan to prevent AI-fueled "answer-seeking" during high-stakes exams. Major platforms now lock exam-related features during test hours — no photo-based solving, no essay generation, no problem explanation. Only non-exam features remain.
This isn’t about banning technology. It’s about timing. The lockdown is precise: per-function, per-scenario, and temporary. After the exam, everything unlocks.
But here’s the deeper lesson: the real battle isn’t between technology and rules. It’s between intention and action. You can lock the tool, but you can’t lock the mindset. The person who relies on AI to cheat will find another loophole. The person who uses AI to learn, practice, and improve — that’s the one who wins, exam or no exam.
That’s the difference between using technology as a crutch and using it as a second brain. And that’s a choice that no lockdown can prevent.
