The Best Artificial Christmas Trees, as Blind-Judged By Interior Designers

WIRED

WIRED brought 10 of the most popular artificial Christmas trees into a studio and got three interior designers to pick the best through blind judging. For extra trimming, we checked in on how those trees fared once they were taken home and decorated. Shopping for an artificial Christmas tree can be overwhelming, especially when you're doing it online. You'll find yourself staring at product photos, wondering: How realistic does it look? Will it shed all over my living room? Can you see daylight through the branches? Are the branches strong enough to hold that lopsided homemade macaroni ornament you've hung on your tree since 2004? We got tired of guessing, so we did a little experiment. We brought 10 of the most popular artificial trees from three top brands (Balsam Hill, King of Christmas, and National Tree Company) and hauled them to a photo studio in Kansas.

MarketGen: A Scalable Simulation Platform with Auto-Generated Embodied Supermarket Environments

arXiv.org Artificial Intelligence

The development of embodied agents for complex commercial environments is hindered by a critical gap in existing robotics datasets and benchmarks, which primarily focus on household or tabletop settings with short-horizon tasks. To address this limitation, we introduce MarketGen, a scalable simulation platform with automatic scene generation for complex supermarket environments. MarketGen features a novel agent-based Procedural Content Generation (PCG) framework. It uniquely supports multi-modal inputs (text and reference images) and integrates real-world design principles to automatically generate complete, structured, and realistic supermarkets. We also provide an extensive and diverse 3D asset library with a total of 1100+ supermarket goods and parameterized facilities assets. Building on this generative foundation, we propose a novel benchmark for assessing supermarket agents, featuring two daily tasks in a supermarket: (1) Checkout Unloading: long-horizon tabletop tasks for cashier agents, and (2) In-Aisle Item Collection: complex mobile manipulation tasks for salesperson agents. We validate our platform and benchmark through extensive experiments, including the deployment of a modular agent system and successful sim-to-real transfer. MarketGen provides a comprehensive framework to accelerate research in embodied AI for complex commercial applications.

Jeff Bezos' New AI Venture Quietly Acquired an Agentic Computing Startup

WIRED

Jeff Bezos' New AI Venture Quietly Acquired an Agentic Computing Startup Project Prometheus has raised over $6 billion in funding and hired over 100 employees, a handful of whom joined through its acquisition of General Agents, according to records and sources. In early June, tech entrepreneur Vik Bajaj took over Saison, a two-Michelin star restaurant in San Francisco, for an off-the-record dinner to talk about AI with journalists and a handful of scientists. In attendance was Sherjil Ozair, a late addition who had previously held senior research roles at DeepMind and Tesla . The following day, Bajaj and Ozair were on their way to making a deal, public records show. Bajaj didn't mention it at the dinner, but earlier this year he had begun working with Amazon executive chairman Jeff Bezos on a new AI venture called Project Prometheus.
