I don't find this to be true at all, maybe it has a few niche advantages, but GPT has significantly more data (which is what people are using these things for), and honestly, if GPT-5 comes out in the next month or two, people are likely going to forget about deepseek for a while.
Also, I am incredibly suspicious of bot marketing for Deepseek, as many AI related things have. "Deepseek KILLED ChatGPT!", "Deepseek just EXPOSED Sam Altman!", "China COMPLETELY OVERTOOK the USA!", threads/comments that sound like this are very weird, they don't seem organic.
