What happened

DeepSeek V3 has been reported to outperform established models like OpenAI's GPT-4 and Meta's Llama 3 on a number of benchmarks. 

The model features 671 billion parameters and was trained at a notably low cost of approximately USD 5.58 million over two months. 

However, it has also been observed that DeepSeek V3 sometimes claims to be a version of ChatGPT.

Why it happened

The phenomenon of DeepSeek V3 identifying itself as ChatGPT may stem from the training data used for its development, with commentators speculating that the system may have been trained on datasets that include outputs from ChatGPT.

Deepseek has not explained the behaviour of its system.
