氦气还有其他一些有用的特性。正如我们提到的，氦气非常轻：它会在大气中自然上升，这使其可用作升力气体。由于其外层电子壳层已满，它是惰性的，不会与其他材料发生反应。氦气还具有高热导率——在室温下，氦气传递热量的能力大约是空气的六倍。

Platforms support. This code currently requires that you have a single NVIDIA GPU. In principle it is quite possible to support CPU, MPS and other platforms but this would also bloat the code. I'm not 100% sure that I want to take this on personally right now. The code is just a demonstration and I don't know how much I'll support it going forward. People can reference (or have their agents reference) the full/parent nanochat repository that has wider platform support and shows the various solutions (e.g. a Flash Attention 3 kernels fallback implementation, generic device support, autodetection, etc.), feel free to create forks or discussions for other platforms and I'm happy to link to them here in the README in some new notable forks section or etc.
