To Read Its Features, Give the Layer a Wider Basis
A sparse autoencoder trades the neuron for an overcomplete dictionary whose directions each carry one checkable meaning; the wins and the pushback arrive together.
A small draft model makes Chinchilla 70B decode 2.5× faster without changing its distribution
A small model proposes several tokens, the large one checks them in a single batched pass, and a modified rejection-sampling test keeps or corrects each so the target's exact distribution survives, a gain that pays off only while decoding stays memory-bound at low batch size.
Feeding high-risk babies peanut early prevents the allergy
The randomized LEAP trial cut peanut allergy in high-risk infants from roughly 14 in 100 to 2, the general-population evidence is thinner, and the benefit depends on sustained feeding in a choking-safe form.
Carbon Capture's Real Fight Is Cement's Chemistry Against the Oil Field
Climate models cannot close their books without it, most of the CO2 captured today is sold to push more oil out of the ground, and named engineers stake careers on both facts.
Iran strikes two UAE oil tankers in Hormuz
Washington's threat to toll a strait it does not own turns a military standoff into an economic one and carries Brent past $85.
A side network restores the safety fine-tuning strips
What helps someone shipping a model tonight sits in a handful of day-old arxiv papers rather than the launch feed, and in a $5.34 billion deal that reads the compute bottleneck as electricity instead of silicon.
