This I haven't heard. Did they put dedicated machinery in there that can *only* be used for LLM training?
Generally, the same math used to train LLMs can be used to solve other problems; I wouldn't be surprised if part of their computation of cost / benefit here was "Even if LLMs don't pan out, oh no, we filled a room with fast linear algebra solvers, guess we'll just have to... Model nuclear physics for the next generation of reactors or fold proteins or something."
