Jev introduces a new shape of LLM - System One, aka Decision Models simonwillison.net

Last week TypeSafe AI unveiled Jev , their first example of a new category of model that they are calling “System One models” (I’m with Maggie Appleton, I think “decision models” is a better name for these). Jev is an interesting variant on the usual LLM format: it still accepts text inputs, but instead of text output it returns floating point numbers corresponding to categories, yes/no questions, ratings, and associated confidence scores. TypeSafe describe Jev like this: Think of Jev as a fron…

The US spent billions on border surveillance. Why can’t it catch people before they die? technologyreview.com

When José Morales Bernal crossed the border into the United States on April 8, 2024, the day before his 32nd birthday, it should have triggered a chain of technological alerts and human responses. As he walked through the desert in southern New Mexico that morning, he was within range of three surveillance towers. Newly installed…

How we made the first comprehensive map of deaths along the US border’s “virtual wall” technologyreview.com

Our 15-month investigation into death and surveillance along the US-Mexico border began with a simple question: Why did so many people die near government surveillance towers meant to help track and apprehend them? This story is part of Dying on Camera, a collaboration between MIT Technology Review and Times of San Diego. Journalists in both newsrooms spent the past…

4 ways to address the failures we found along the US border’s “virtual wall” technologyreview.com

MIT Technology Review today published our investigation into how many people have died near the “virtual wall” of surveillance towers that the US government has installed along the US-Mexico border. We found cases of people who walked undetected through areas surveilled by advanced, AI-enabled towers and later died nearby, where their bodies remained unnoticed for…

She died at the San Diego border. A surveillance camera was in plain sight technologyreview.com

She had only walked for a couple of hours, and already she was lost. It was early afternoon on Sept. 14, 2025, when 30-year-old Graciela Gómez Hernández crossed the border from the eastern edge of Tijuana into Southern California, sending voice messages to her mother and sister as she walked. This story is part of Dying…

Amazon blocks Meta’s Muse AI agent theverge.com

Amazon began showing popups Sunday telling Muse users that unauthorized AI agents violate its terms of use, cutting off Meta’s assistant without prior notice. The block underscores platforms’ growing willingness to fence out rival agents, especially when they compete with in-house models and inference services.

Kev-9B currently serves as one of the leading open-weight contenders with a Decision Index score of 50.5, though it still trails the proprietary Jev reference model, which scores 59.5. Kev-4B scores 47.4, while the tiny Kev-0.8B reaches approximately 31.3.

Independent developers have already released ‘clones’ like Laya and Nimble, demonstrating that standard off-the-shelf RL and LoRA adapters on existing models can replicate Jev’s behavior — critics reference ‘getting Schmidhuber’d’, arguing Jev’s novelty lies in DX rather than fundamental architecture.

Chambers & Boyce, ‘Mortality, Surveillance and the Tertiary Funnel Effect’ (Academia.edu) academia.edu

Geospatial modeling shows migrants avoiding viewsheds of surveillance towers must expend an average of 925.98 additional calories per journey, corralling them into more rugged, low-visibility terrain where the physiological risk of death from dehydration and hyperthermia rises sharply.

GIJN — ‘Mapping Migration Deaths with GIS Modeling’ gijn.org

‘Out here, surveillance equals death,’ Chambers said, explaining that as cameras proliferate, migrants take longer, riskier routes that maximize physiological stress.

Context News (Thomson Reuters Foundation) — ‘Surveillance tech makes US-Mexico border even deadlier’ context.news

Independent reporting corroborates that the ‘smart wall’ functions less as a rescue tool than as a deterrent that weaponizes terrain, with humanitarian groups documenting bodies recovered directly within camera line-of-sight.

Times of San Diego — investigation partner brief timesofsandiego.com

The 15-month collaboration cross-referenced nearly 4,000 migrant death locations with tower coordinates, using Anthropic’s Claude API to extract geographic data from over 4,000 pages of police and medical examiner records before manual verification.

Uma Incerta Antropologia (republication with Anduril statement) umaincertaantropologia.org

Anduril told investigators that once towers are delivered, they are operated exclusively by CBP, and that proximity of a death to a tower does not equate to a system failure because CBP configures ‘virtual boundaries’ and topography can obstruct autonomous detection.

KuCoin news summary of House Homeland Security oversight kucoin.com

House Homeland Security Committee testimony in September 2026 flagged that roughly two-thirds of Remote Video Surveillance System towers are non-functional, with FAA maintenance stalled by obsolete software and contractors lacking required background checks.
