The warning

AI systems can give detailed help relevant to making biological and chemical weapons. In 2025 several developers added stronger safeguards because they could not rule out meaningful help to novices.

What the registry shows

Research vs reality · International AI Safety Report →

How we match: a case file is linked to a warning when what happened is a real-world instance of the risk the source describes, judged by the editors from the facts in the case file. A match means the case fits the warning, not that it proves the source's wider argument. Allegations in lawsuits are labelled as allegations. Statuses are editorial and reviewed as new cases arrive. The matching is recomputed on every update. Data: Systematic coverage in the registry starts in 2025, so a first-case date shows when the registry first recorded the risk, not when it first happened. research.json (CC BY 4.0)
