I am interested in ChaptGPT and DeepSeek comparison. Since I'm interested in Northern College Literary before the Civil War, I wanted to compare it with ChatGPT and DeepSeek. I was very impressed with them both, obviously.
But ChapGPT 3.5 was more in-depth than DeekSeek, I think. The ChatGPT is there. The DeepSeek is there.
The ChatGPT 3.5 is also here. (This "Northern College Address" is Al Brophy's chatGPT.)
Perplexity is also here.
