> quant HFT is pretty decent mental exercise and it has given them “deep” brain muscles. that’s my take.

It's quite crazy that it's Deepseek's background/original purpose. We already had very advanced stuff from the world of HFT, but now a frontier family of models from a private company that used to be (still is?) in HFT is plain bonkers.

Is more known about them and the HFT background?
