Google's in-orbit TPU completes AI inference for the first time, Gemma 4 generates a haiku
Google announced that a data-center-class TPU running in orbit aboard its "Project Suncatcher" prototype satellite has for the first time produced an AI response; the pre-installed DeepMind model Gemma 4, following a prompt from ground engineers, composed a haiku about being in space. The satellite carries four TPUs and can generate up to 1 kilowatt of electrical power; limited by heat dissipation and energy load, it can only be powered on for about 20 minutes at a time, and the test focuses on verifying the chip's stability and error-correction capability under microgravity, severe temperature swings and the space radiation environment.

Thanks to IT Home users Yugong Qima and Huanan Wu Yanzu for submitting the tip!
IT Home, October 31 news: On October 1 local time, Google successfully launched the prototype satellite for "Project Suncatcher." Over the following weeks, the team gradually completed the in-orbit testing and commissioning checklist, including powering up the host and TPU tray, and successfully completed early machine learning tests.
On October 30 local time, Google announced that it had reached the "Hello World" milestone: the data-center-class TPU operating in orbit delivered its first AI response.
This week, when ground engineers sent the first prompt, they asked the Google DeepMind model Gemma 4 pre-installed on the satellite to compose a haiku about being in space. The model responded as follows:
In addition to the haiku, engineers also tested telemetry tasks such as limerick generation and the return of orbital environment data.
It is reported that the satellite carries four Google TPUs, can generate up to 1 kilowatt of electrical power, and is intended to lay the foundation for building a tightly formation-flying satellite network in the future for executing large-scale inference workloads in orbit.
Limited by heat dissipation and energy load, the onboard TPUs can only be powered on for about 20 minutes at a time. The core of the test is to verify the stability and error-correction capability of the chips under microgravity, severe temperature differences, and the space radiation environment.
