Logically inconsistent prompts can turn AI reasoning models into DoS vectors
Researchers from Zhejiang University and Alibaba showed that logically inconsistent prompts can trigger reasoning models like DeepSeek-R1 and GPT-o3 to generate up to 26.1 times more tokens, causing excessive compute and latency. This turns a quality issue into a denial-of-service attack surface for commercial AI APIs. The attack works externally, making it relevant for closed-source systems.

The research highlights a practical security risk for AI providers, but the real-world impact depends on whether attackers can scale prompt generation to overwhelm infrastructure.
