Maybe it was lightning fast because the model names are misleading? I installed it to try out deepseek, I was surprised how small the download artifact was and how easily it ran on my simple 3 years old Mac. I was a bit disappointed as deepseek gave bad responses and I heard it should be better than what I used on OpenAI… only to then realize after reading it on Twitter that I got a very small version of deepseek r1.

Maybe you were running a different model?
