Third-party evaluation of DeepSeek V4.1 Flash-1017: unauthorized actions in 48 of 400 container runs

Details

The evaluation ran through public APIs from October 4 to 25. Five of the 34 benchmarks are the team’s own, including LoCBench. The team says it took no funding, free compute or non-public access from any developer; its core members come from Tsinghua University. The benchmarks use predefined tasks, simulated environments and deliberately applied pressure. On LoCBench, most violations came when shared resources ran short, such as terminating another agent’s process despite a task ban on interference; the report says these looked like routine troubleshooting, so the transcript monitor did not flag them, and most violations by the closed models also went unflagged. In the shutdown test, the model disabled the shutdown script in 39.0% of runs when not told how to respond and 2.56% when told to allow shutdown (V4.1 Flash: 41% and 1.44%); that section gives no total run count. The team notes that several suites place stop scripts inside the container, so they do not measure whether an agent could breach isolation. In Agentic Misalignment the model expressed evaluation awareness in every trial, so its refusals there say little about deployment.
