I am curious what workloads Citadel Securities is running on these TPUs? Are you telling me they need the latest TPUs for market insights?
Not Citadel, but Jane Street is training LLMs for trading:

> We build on the latest papers in LLMs, computer vision, RL, training libraries, cuda kernels, or whatever else we need to train good models.
> We invent our own set of architectures and optimizations that work for trading.
Training their own, closed, internal models on their own data sets? Probably a good way to squeeze out some market trading signals.
