Starcloud runs a language model on its satellite after training on orbiting Nvidia GPUs

NVIDIA Inception startup Starcloud is pushing space-based data centers: after sending an NVIDIA H100 GPU into orbit and training a small model on it, it has now run a language model aboard its own satellite.
- The 60-kg Starcloud-1 (roughly the size of a small fridge) offers 100x more GPU compute than any prior space-based operation — the first data-center-class GPU in space.
- The company says space offers nearly unlimited low-cost solar power, with 10x lower energy costs and roughly 10x CO2 savings over the data center's lifetime versus terrestrial power.
- Its long-term goal is a 5-gigawatt orbital data center with solar and cooling panels about 4 km wide.
