NVIDIA’s Nemotron 3.5 Super VL (120B open) plus Bolt edge models aim to cover always-on agents from server rack to RTX laptop.

NVIDIA folds vision, documents, video and tool use into one open 120B mixture-of-experts model, betting enterprises would rather post-train a single agent brain than stitch several together.

Microsoft's prep for Nvidia's Arm-based RTX Spark laptops shows where the AI PC is heading: two-click local agents, tuned emulation, and a delayed Recall.

Google's Universal Cart is live in the US, turning Search and Gemini into a persistent cross-retailer shopping list wired into its own agent checkout standard.
CopilotKit’s CLiF turns agent traces and user actions into skills, evals, and fine-tuning data — closing the loop agents keep failing in production.

GeForce NOW hands members DLSS 4.5 controls, letting cloud gamers tune AI upscaling and frame generation without owning the latest hardware.

For Teachers' Day, OpenAI ships a Portuguese AI for Educators course and pushes Study Mode — a bet that AI should ask questions, not just hand over answers.

Timed for Black Friday, Google's Universal Cart arrives in Search and Gemini — with Gmail and YouTube next — as Big Tech bets bots will do our shopping.
