   Edge AI Daily Morning Brief: Alphabet stock falls 12.6% after earnings; NVIDIA open-sources Nemotron 3.5…

   Alphabet reported third-quarter 2026 earnings per share of $2.12, far below Wall Street's expected $3.02; its stock closed down 12.6% after the earnings report, with market value evaporating nearly $500 billion in a single day. NVIDIA opened the weights of the Nemotron 3.5 Transcribe model on October 28, 2026; it uses a MoE architecture with about 34 billion total parameters, activating only about 4.3 billion per forward pass, supports transcription in 40 languages, and can distinguish up to 8 speakers. Since June 2026, Anthropic has run a "self-evaluation" safety mechanism in production that can catch 78% of violating conversations flagged by a heavy prompt classifier, with a 94% detection rate for high-risk abuse, at an additional inference compute cost of less than 2%.

   Google's first data center satellite goes online, writes haiku in orbit using Gemma 4

   After about three weeks of in-orbit testing and calibration, Google's first data center satellite carrying a TPU has entered its formal operational phase. This week, engineers sent prompt instructions to the satellite for the first time, and the pre-installed Google DeepMind Gemma 4 model composed a haiku about space. The satellite can generate up to about 1 kilowatt of power; because the TPU has relatively high power consumption, the chip can only be powered on for about 20 minutes at a time. Google will next evaluate the TPU's reliability under temperature changes and cosmic radiation. If it is verified to be stable, the company plans to launch two more follow-up satellites in 2027 using more advanced chips.

   Google Suncatcher's first data center satellite goes online and completes in-orbit inference

   Google Suncatcher's prototype space data center satellite has gone online and communicated with the ground; earlier this month it launched aboard a SpaceX Falcon 9 rocket along with more than 100 other spacecraft. The satellite carries a single Google TPU with a maximum power generation of 1 kW, and due to power constraints it can only be powered on for about twenty minutes at a time; after about three weeks of in-orbit commissioning, ground engineers this week sent the first prompt, asking the pre-installed Google DeepMind Gemma 4 model to write a haiku about space and to report on the orbital conditions around the satellite. Subsequent tests will examine the chip's performance under thermal stress and the space radiation environment; if this TPU performs up to standard, Google plans to launch two more satellites carrying the chip in 2027 to validate higher power generation and inter-satellite optical links.
