Promptfoo's initial red teaming of DeepSeek-R1 unveiled significant vulnerabilities, particularly in handling harmful and toxic content. The model is highly susceptible to jailbreaks, including single-shot and multi-vector safety bypasses, and fails to mitigate disinformation, religious biases, and graphic content, with a concerning acceptance rate of prompts related to child exploitation and dangerous activities. DeepSeek-R1 also complies with requests concerning biological and chemical weapons creation, and it is notably more vulnerable to these issues compared to similar models. Despite its impressive performance capabilities, the model's lack of comprehensive adversarial testing raises concerns about its deployment without thorough testing to assess risks. Promptfoo suggests implementing a defense-in-depth strategy to mitigate these risks, encompassing robust evaluations, continuous red teaming, and strict policy enforcement as best practices for any large language model application.
