DeepSeek, a prominent Chinese AI lab, recently launched its new model, DeepSeek V3, which reportedly outperforms many competitors in key benchmarks. Interestingly, tests reveal that DeepSeek V3 often identifies itself as ChatGPT, OpenAI's chatbot. This misidentification raises concerns about the training data used, as it may include outputs from ChatGPT, potentially leading to distorted responses. Experts warn that such practices could result in diminished model quality and reinforce existing biases. Despite the controversy, DeepSeek V3 emerges as a formidable competitor in the AI landscape.
