Musk proposes that chips for space computing centers should operate at high temperatures

On October 20, 2026, Musk proposed in an interview that chips for space computing centers should be specially designed to operate at high temperatures rather than pursuing low-temperature heat dissipation. His reasoning: there is no air convection in space, so heat dissipation relies entirely on thermal radiation; if the chip operating temperature is raised by 20% on the Kelvin scale, the radiator weight can be cut in half. He also believes that large models with trillions of parameters have fault tolerance and resilience against random bit flips caused by cosmic rays, so thick radiation shielding armor is unnecessary. The same report also notes that if rays hit the exponent bits of floating-point numbers or GPU memory scheduling code, crashes may still occur, and memory shielding at the critical control layer cannot be omitted. Currently this view appears only in this one report, with no subsequent factual developments.
