Is Deepseek Using OpenAI? API Response Suggests So

I used OpenRouter AI API with the deepseek-chat model, but when I asked “Who are you?” it responded, “I’m an AI language model created by OpenAI, called ChatGPT.”
Does this mean Deepseek is actually using OpenAI? Or is OpenRouter misleading us? Has anyone else experienced this?

Deepseek is trained using openai - it doesn’t communicate with it in real time, from what I gather.
