Amazon Web Services is marking its entry into the lucrative business of providing the U.S. government with artificial intelligence and high-performance computing services via purpose-built infrastructure for which it has committed up to $50 billion in construction and equipment. The investment “will add nearly 1.3 GW of compute capacity across AWS Top Secret, AWS Secret, and AWS GovCloud (U.S.) across all classification levels,” Amazon says, adding that the commitment “expands access to AWS’s trusted infrastructure” and advances America’s AI leadership and enables U.S. agencies “to accelerate discovery and decision-making.” Read more

Amazon is playing catch-up to Elon Musk’s Starlink with its satellite-based Internet service Leo, the rebrand of Project Kuiper. Leo is previewing a gigabit-speed “Ultra” antenna for business customers. Amazon claims that Leo Ultra is “the fastest customer terminal in production,” with download speeds of up to 1 Gbps and upload speeds that max at 400 Mbps. Amazon Leo has “more than 150 satellites in orbit” with “initial network testing underway” and plans to have a total of 3,000 satellites. Because it’s satellite rather than terrestrially based, Leo is accessible in areas without reliable connectivity, anywhere on the globe. Read more

OpenAI is live with a retail companion it calls “shopping research” that helps consumers find viable purchase options based on detailed requirement parameters. Trained on a version of GPT‑5 mini, it can query on a virtually unlimited list of discovery constraints, sourcing only from “reliable retailers.” “Results are organic and based on publicly available retail sites,” OpenAI says, indicating there are no advertiser-boosted entries — not yet, anyway. Available on iOS, Android and the Web for logged-in ChatGPT users on the Free, Go, Plus, and Pro plans, OpenAI is making nearly unlimited usage available to all plans through the holidays. Read more

Snapchat is adding community conversations under the header Topic Chats. Aiming to stimulate public discourse on news, events and other trending topics, Snap will be aggregating the threads across the app in the coming weeks for users in the U.S., Canada and New Zealand. Chat shortcuts, search, the Stories page, and Spotlight videos will feature “a big yellow button” that says “Join the Chat” inviting users to the parley. Profiles will stay private to those who a user is not friends with, a feature intended to help avoid unwanted friend requests and direct messages. “This is new for Snapchat, because we’ve primarily focused on supporting private conversations rather than public ones,” Snap notes.
