Simon Willison15 @therealcornpop on why AI-written scripts are easy to spot
TikTok creator @therealcornpop says AI-written TikTok and YouTube scripts are easy to spot—not only because of stock phrases like “not X, but Y,” three-part structures, or choppy sentences, but because they lack a clear voice or position, revealing that the writer has no personal view on the subject.

Simon Willison71 TypeSafe AI releases Jev, a System One model that outputs only floating-point decisions
TypeSafe AI released Jev last week, a new category it calls a System One model (the author prefers “decision models”). It accepts text input but returns floating-point values for categories, yes-or-no decisions, scores, and confidence rather than text.
Latent SpacePicks76 TypeSafe AI founder Diogo Almeida on Jev and RLCD: building System 1 models for software, not chat
In a Latent Space interview, TypeSafe AI founder Diogo Almeida introduces Jev as a System 1 model designed for code consumption and optimized for intelligence per dollar rather than chat experience.

Microsoft Research40 Microsoft open-sources RetroChimera retrosynthesis model in a paper published in Nature
Microsoft has published RetroChimera, a retrosynthesis-prediction framework, in Nature and open-sourced its implementation and weights. It combines the Transformer model R-SMILES 2 with the GNN model NeuralLoc, using a learned ensemble to rerank their predictions and performing strongly on both common and rare reaction types. In blind tests, chemists preferred its single-step reaction predictions. It found complete routes for nine of ten challenging targets, compared with five for a de novo model, four for an editing model, and two for NeuralSym.
NVIDIA Blog36 NVIDIA on AI safety: engineering controls at every layer of the agent stack
NVIDIA argues that AI safety is an engineering problem requiring enforceable controls, clear ownership, and verification evidence, and says safety boundaries must operate independently of agent reasoning. Its open-source NVIDIA OpenShell safety runtime enforces policies outside an agent's reach and provides sandboxed execution. Cisco DefenseClaw and JFrog have built governance and skill-scanning capabilities on top of it.
Import AI22 Import AI 473: U.S. superintelligence strategy, human brain tissue grown in mouse skulls, and machine hermeneutics
RAND published a long report recommending that the United States pursue a “free action” strategy amid uncertainty about the path to superintelligence, investing in AI safety, verification tools, and regulatory capacity to preserve its options instead of committing too early to one approach. Other research described growing partial human brain tissue inside mouse skulls and explored machine hermeneutics.
MIT Technology Review · AI48 MIT Technology Review investigation into deaths at the U.S. border's 'virtual wall' offers four recommendations
A MIT Technology Review investigation found systemic failures in the AI surveillance towers that make up the U.S. border “virtual wall”: equipment failures, missed detections, and agents not responding to alerts. More than 1,050 people have died, and the true number may be higher. The U.S. government plans to spend $1 billion by 2034 to double the virtual wall's size, while CBP has never audited deaths near the towers. The report offers four recommendations, including auditing deaths, fixing the migrant-death tracking system, and documenting arrests aided by surveillance technology.
