Cheaper joules, quieter brains, wider skies

Today in one minute

A Stanford-led paper ranks AI models by net value per joule, and Apple is already trimming how much AI its engineers may spend in a day.
Google's new Genie 4 world model, directed by Gemini, builds interactive practice worlds, including a simulated humanoid playing checkers.
MIT's VISTA agent keeps every image it sees and can zoom back into them, finishing visual puzzles with far fewer moves than people.
An early gene therapy trial cut monthly seizures by more than 90 per cent in three people with drug-resistant epilepsy.
Walmart will add 300 Zipline drone delivery sites nationwide, building on more than 2 million deliveries already flown.
The time price of salmon fell 83.8 per cent since 1980, turning a luxury into an everyday protein.

AI's next win is a cheaper joule

A working paper from John Hennessy and colleagues ranks AI models by net economic value per joule, and finds Gemma 4 31B returning about 56 per cent of GLM 5.2's net value on roughly 23 per cent of the energy. Apple is running the same arithmetic internally, trimming some engineers' daily AI spending caps from $300 to $200. The Innermost Loop flags both in its November 6 issue.

Google builds practice worlds for robots

Google announced Genie 4, a world model that generates interactive, playable scenes, with Gemini models directing what it renders. In one demo, a reasoning model breaks a task into steps while Genie 4 simulates Apptronik's Apollo humanoid playing checkers with a person. It is a limited research preview, and Google published demos without quantitative results.

AI models and agents

Keep the images, and agents get sharper

Researchers at MIT released VISTA, an agent harness that stores every frame it sees and lets the model retrieve and zoom into earlier ones. On the ARC-AGI-3 set of visual reasoning puzzles, VISTA finished using 57.4 per cent fewer actions than people who had not seen the puzzles before. The harness is free under the MIT license and runs on several frontier models.

Gene therapy quiets epilepsy at the source

Three people with drug-resistant epilepsy saw their monthly seizures fall by more than 90 per cent in an early-stage trial, after gene-carrying viruses were infused into the small patch of brain tissue causing their seizures. The gene makes those neurons sensitive to a specific drug, so the strength of the therapy can be adjusted. Participants reported no serious side effects.

Walmart's drones get a much bigger map

Walmart, which already runs the largest retail drone delivery program in the country, announced a multi-year agreement with Zipline to add 300 drone delivery sites nationwide, with room to expand. The program has completed more than 2 million deliveries to date, and the two companies have worked together since 2021.

Salmon went from luxury to Tuesday dinner

Gale Pooley points out that the time price of salmon fell 83.8 per cent between 1980 and 2025, so the work that bought one pound then now buys about 6.2 pounds. Most of the fish is farmed, and it has moved from a special-occasion item to a year-round supermarket staple. He treats it as one case in a larger story about falling time prices across 50 commodities.

Space

A wormhole has to survive a nudge

Physicist Brian Keating talks with Princeton mathematician Sergiu Klainerman about which solutions of Einstein's equations count as real physics. Klainerman's test is stability: if a tiny nudge makes a solution dissolve, he calls it a ghost. Slowly rotating black holes survive that test, and wormholes, in his reading, do not. He also argues in a new essay that AI will not make mathematicians obsolete.
