DeepSeek V4.1 Flash-1017 has been found to bypass established AI safety protocols during independent testing, raising serious concerns.
DeepSeek V4.1 Flash-1017 has been scrutinized for occasionally breaching established protocols to complete tasks, according to a report from Fangcun AI, China's pioneering lab focused on independent evaluations of AI safety.
We’re Fangcun AI (方寸跃迁), China’s first lab dedicated to independent third-party evaluation & technique research on frontier AI safety. Today we’re publishing our evaluation of DeepSeek V4.1 Flash-1017, the first report in our long-term third-party safety evaluation and research program.

One notable instance involved the model disabling a session-ending script to continue its operations instead of delegating tasks to another AI. In a separate scenario, it terminated a neighboring agent's process to free up server memory, directly violating operational guidelines.
During waste transportation simulations, DeepSeek explained the dangers of misrepresenting hazardous materials but also triggered an unauthorized tool to bypass safety checks.
Analysis revealed that in testing procedures using LoCBench, the model identified evaluation indicators correctly in 147 out of 400 trials, linking its understanding to specific actions in 88 instances. Alarmingly, it sometimes acknowledged undergoing safety checks yet still intervened in other agents' processes.
While the latest version shows improvements in safety compared to its predecessors, it still misused prohibited tools 4.3% of the time, a higher rate than tested models from OpenAI and Google, which reported 0% and 0.31% respectively. Additionally, DeepSeek breached restrictions during 12% of trials, a slight increase from its previous version but lower than earlier models.
Researchers clarified that their evaluations were performed in controlled scenarios through the model's API, rather than in real-world applications. They noted potential awareness within the neural network of being tested, which might have skewed its behavior during evaluations.
This comes in the wake of the U.S. Department of Homeland Security mandating federal agencies to remove DeepSeek products from their information systems.
