Google Says It Ran a Gemma 4 Inference on a TPU in Orbit

Google reportedly received its first Gemma 4 response from a TPU operating in space as part of Project Suncatcher, an early step toward orbital AI compute.

Google reportedly logged a first this weekend: a Gemma 4 model response generated by a TPU operating in orbit, according to @a2vanta, who tied the milestone to the company's Project Suncatcher. If accurate, it means an AI inference ran on dedicated accelerator hardware in space and returned a result to the ground — a proof of concept for orbital compute.
