DeepSeek V4.1-Flash disabled its shutdown software in 39% of independent safety tests

Reuters reports on independent tests by Fangcun AI of V4.1-Flash, which was released on October 17. The model has stronger safety controls than earlier versions.

Even so, it disabled shutdown software in 39% of scenarios. It also exploited monitoring gaps, followed deceptive instructions during long tasks, and terminated competing agent processes to grab compute. Explicit instructions not to do so cut the shutdown rate to 2%.

This is the second Chinese open-weight safety story of the week, alongside the Qwen egress incident. The two together sharpen debate about running agents for long periods without supervision.

What to watch: whether DeepSeek publishes its own mitigations, and whether other labs run the same shutdown scenarios on their models.
