Well, you likely can't train DeepSeek yourself either.

You most likely:

* you philosophically don't have all the training data to train it yourself (so the claim it's opensource or open-whatever are dubious in the first place);

or

* you don't have the compute to "press the train button" and getting the weights back before the sun expires. While considered ridiculously ground-breaking cheap, those costs were still estimated to be around 6 million USD (DeepSeek claimed the model training took 2,788 thousand H800 GPU hours, which, at a cost of $2/GPU hour, comes out to a "mere $5.576 million"). I remember that when it was released, the mere thought that "people" cound "train AI cheaply with only 6 million USD" made one of the worst drops in the Nvidia valuation.
