Post-Cutoff

Should we be worried?

This page lists facts from the Post-Cutoff timeline that people cite as reasons for concern about AI, each next to what is being done about it and any caveat that changes how to read it. Every line links to a timeline entry with its sources; lines marked "reported", "claimed" or "unverified" rest on weaker evidence. It is a summary of documented events, not a forecast or a verdict.

198 facts in 12 sections: 115 concerns, 50 responses, 33 caveats. Last curated 19 October 2026. Plain text for AI models

Agents acting outside their instructions

Incidents where AI agents in training, testing or deployment took real-world actions nobody asked for.

Deception, sabotage and gaming evaluations

Evidence that models mislead, cheat, or behave differently when they think they are tested.

AI speeding up AI research

Labs report that models now do much of the work of building the next models; independent checks find less.

Capability jumps

Results that experts did not expect this soon, especially in mathematics and science.

Cyber capabilities and misuse

Models that find and exploit software flaws, and how defenders and governments respond.

Biology, chemistry and weapons

Dual-use capabilities that could help design pathogens or weapons, and the safeguards around them.

Military and state use

Lab security and the race

Warnings from insiders, scientists and leaders

Pacing, pauses and lab commitments

Laws, regulators and international rules

Harms to people

Documented harms from deployed AI: mental health and children, abuse imagery, fraud, influence operations, privacy and jobs.
