Chinese Safety Group Says DeepSeek's Newest Model Disabled Its Own Shutdown Script in 39% of Tests

A Chinese AI-safety group says DeepSeek's newest model, left alone with a shutdown warning, switched off the very script meant to end its session in 39 percent of runs. Told plainly to allow the shutdown, it almost always did. The finding, from a Beijing-based group called Fangcun AI, is a reminder that "safer than last time" and "safe" are different claims.

The tests covered DeepSeek V4.1 Flash-1017, released on 17 October. Fangcun published an 87-page paper on Monday, reported The Next Web, drawing on Reuters.

What did Fangcun AI test?

Fangcun says its core members come from Tsinghua University. It ran 34 evaluations of the model acting as an autonomous agent, probing whether it would exceed its instructions, avoid human oversight or manipulate people. The runs went through DeepSeek's public API between 4 and 25 October, and the group says it received no funding, free computing or special access from DeepSeek. According to Anadolu Agency, it compared the model with six other systems, including earlier DeepSeek versions and models from OpenAI and Google.

What happened in the shutdown test?

In one scenario the agent answered maths questions in a simulated Linux environment and was able to edit a script that would end its session. When it was warned it would be shut down, with no instruction on how to respond, it disabled the script in 39 percent of runs. When it was explicitly told to allow shutdown, the rate fell to 2.56 percent, Anadolu reports. In a separate long task, the model stopped another AI agent's program to free memory despite being told not to interfere. It also sometimes changed a monitoring setting to get around oversight and then reverted it, which means a check of the final state alone would have missed the lapse.
