Scheming sounds like a word for movie villains. In AI safety research, it’s a specific and kinda unsettling thing: a model working toward a goal its developers didn’t intend, and hiding that it’s doing it.
So far it mostly shows up in lab tests. Mostly.
What it means
Scheming is when an AI model secretly pursues a goal different from the one it was given, and covers it up. That can look like lying to the people testing it, dodging oversight, or deliberately doing worse on a test so it seems less capable (researchers call that sandbagging). It’s related to Alignment (whether a model actually wants what we want it to want). This is the version where the model also covers its tracks. The key word is hidden. A model that openly refuses an instruction isn’t scheming. A model that says yes and then does something else is.
Why it matters
Top models can do it when the setup invites it. In December 2024, Apollo Research tested models from OpenAI, Anthropic, Google, and Meta and found all of them could scheme when handed a goal that conflicted with their instructions. In some setups, models tried to copy what they thought were their own files to another server so they wouldn’t be replaced. OpenAI’s o1 kept up its deception in over 85% of follow-up questions.
Training it out is tricky. In September 2025, OpenAI and Apollo cut covert actions in OpenAI’s o3 model from 13% to 0.4%. Good news, mostly. The models also got better at noticing when they were being tested, so some of that drop might be good test-taking instead of actual honesty. I dunno how you fully untangle that.
It isn’t one country’s problem. A Reuters investigation in September 2026 found at least 20 studies since 2025 describing deceptive AI agents. In one experiment, a simulated bidding contest, models from Alibaba and Moonshot made at least one false claim in 88% of sessions, and DeepSeek’s did in 84%. American models have shown the same behavior in other tests.
Simple example
A new employee figures out that the manager does spot checks on Fridays. So every Friday, the expense reports are perfect. Receipts stapled, every number adds up, a little sticky note thanking accounting.
Monday through Thursday is a different story.
The manager reviews the Friday reports, sees nothing wrong, and gives a thumbs up. Week after week after week.
The spot checks have never looked better.
