Google DeepMind 20260423 Decoupled DiLoCo A New Frontier for Resilient Distributed AI Training Summary

Generated by Codex with GPT-5

What happened

Google DeepMind’s official research blog published Decoupled DiLoCo: A new frontier for resilient, distributed AI training, a post about training large language models across distant data centers without requiring every accelerator to move in tight lockstep.

The core problem is that frontier model training still depends heavily on synchronous, single-program multiple-data style execution. That works well when a large block of identical accelerators can synchronize quickly and reliably. It becomes more brittle as training runs span more chips, more sites, and more heterogeneous hardware. A slowdown, network delay, or hardware failure in one part of the fleet can waste capacity elsewhere because global progress waits for the slowest participant.

Scientific American 202512 How Big Can Black Holes Get? Summary

Generated by Codex with GPT-5

The growth problem

Phil Plait’s article starts from a simple question with a surprisingly constrained answer: if black holes can swallow matter and merge with one another, why should there be any practical ceiling on how large they can become?

The question matters because supermassive black holes are no longer exotic exceptions. Astronomers now think that large galaxies commonly host them in their centers. Some weigh millions or billions of times as much as the sun, and the most extreme known examples appear to reach into the tens of billions of solar masses. That scale can make black holes sound almost mythically unbounded, as though enough time and enough available matter would let one grow without limit.

Techmeme 20260430 Anthropic Plan to Expand Mythos Access Is Opposed by White House Summary

Generated by Codex with GPT-5

What happened

Techmeme surfaced this April 30, 2026 story in its Anthropic Mythos cluster, and the direct source used here is Bloomberg’s Anthropic Plan to Expand Mythos Access Is Opposed by White House.

The White House is opposing Anthropic’s plan to broaden access to Claude Mythos Preview, the company’s restricted frontier model for advanced cybersecurity work. Anthropic had proposed granting Mythos access to roughly 70 more companies and organizations, expanding a program that already includes launch partners and dozens of critical software maintainers under Project Glasswing. Administration officials objected on security grounds, and the Techmeme cluster also highlighted Bloomberg’s separate report that the NSA has been testing Mythos to find vulnerabilities in Microsoft products and other widely used software.
