Google’s week of announcements brought together eight AI and product developments across chips, Gemini models, research, robotics, developer tools and consumer devices.

The hardware announcements included TPU 8tx, which keeps data encrypted during processing for government and regulated-sector use, and TPU 8i Max, which combines two 8i chips to support AI agents working with long contexts.

For developers, businesses and Google AI Ultra subscribers, Google opened Gemini 4 Carbon, its model for lengthy coding tasks and cyber defence, at $2 per million input tokens and $10 per million output tokens.

Google also introduced Gemini 4 Hydrogen, a faster, lower-cost model available in the Gemini app, Search, AI Studio and the Gemini API; Sundar Pichai said it completes tasks 2.5 times faster than Gemini 3.8 Flash and offers four reasoning depths.

The Gemini Decisions API, built for quick outputs such as yes-or-no answers, fixed-option selections and scores, offers free output and a free usage tier; its Gemini Decision 1 model costs $0.10 per million input tokens.

In scientific research, AlphaGenome 2 analyzes how DNA changes affect particular cell types using more than 107 million cell profiles; academics can access its API for free, while companies can join a private preview, and the tool is not cleared for diagnosis.

DeepMind’s AlphaProof Code used researcher-supervised AI agents to produce mathematical proofs about Signal’s one-to-one messaging encryption in four weeks, but it did not analyze the whole app and found no new flaws.

Gemini Robotics 2.5 aims to help robots handle tools and soft objects more reliably; DeepMind reported tasks completed 20 to 30 percent faster than with the previous version, along with more cautious behavior around people, and named Apptronik, Boston Dynamics and Agile Robots as initial partners.

Google opened pre-orders for its first Android XR audio glasses, Intelligent Eyewear, developed with Samsung and featuring frames by Warby Parker and Gentle Monster; they bring Gemini audio features, work with Android and iPhone, and are expected to ship during the holiday season.
