The EU AI Act's Article 50 transparency/labeling duties and the Commission's power to fine GPAI providers (up to EUR15M or 3% of global turnover) both activate today, August 2, 2026 -- while the broader high-risk AI system rules were separately deferred to December 2027 (Annex III) and August 2028 (Annex I) via the Digital Omnibus amendment adopted this June.

Kimi K3 (2.8T parameters, ~1.56TB of memory at 4-bit) gets its first dollar-denominated hardware number: AMD's MI355X runs at $2.50/GPU-hr against Nvidia's B300 at $6.00/GPU-hr -- a 2.4x cost advantage for AMD despite B300 delivering roughly 1.65x more aggregate throughput. Separately, an unverified Reddit post claims K3 was run on a single 8GB-RAM CPU.

Today's single highest-voted Hacker News story (467 points/160 comments, ahead of every other story on the board) is a resurfacing 2023 essay arguing Google followed an 'Embrace, Extend, Extinguish' pattern against RSS -- acquiring FeedBurner then gutting it, silently removing Chrome's RSS button, and killing Google Reader in 2013 -- paired same-day with 'Atom is better than RSS, in ways that matter,' anchoring Sunday's Content Aggregation rotation.
