Nanbeige4-3B-Thinking: How a 23T Token Pipeline Pushes 3B Models Past 30B Class Reasoning. Nanbeige4-3B-Thinking shows that a 3B parameter language model, when trained with a 23T token pipeline emphasizing data quality, curriculum scheduling, and reinforcement learning, can achieve reasoning capabilities on par with 30B models. The breakthrough challenges the prevailing notion that performance improvements solely require larger model sizes.

OpenAI has Released the ‘circuit-sparsity’: A Set of Open Tools for Connecting Weight Sparse Models and Dense Baselines through Activation Bridges. OpenAI released the 'circuit-sparsity' toolkit along with weight-sparse transformer models on Hugging Face and GitHub. The tools aim to connect weight-sparse models with dense baselines through activation bridges, potentially improving model interpretability and computational efficiency.

AI data center boom could be bad news for other infrastructure projects. Article [2] examines how a boom in private spending on AI data centers is intensifying competition for construction labor and potentially diverting funds from traditional infrastructure projects like roads and bridges. The report highlights record state and local debt sales and Census Bureau data showing private spending at over $41 billion annually, equating to public transportation spending.
The Performance Edge
Peak performance science for sustained execution in high-stakes environments
📍 The Signal
The brain switch that could rewrite how we treat mental illness. Scientists have identified molecular changes in the brain’s stress response that may reveal a 'brain switch' influencing long-term behavior and resilience. The study suggests new treatment approaches for mental illness that build natural strength rather than simply correcting deficits.
Digital Defense
Threats and defenses shaping the global security landscape
📍 The Signal
Europeans' health data sold to US firm run by ex-Israeli spies. The article reports that the European messaging service Zivver, used for confidential communications by governments and hospitals, has been sold to Kiteworks—an American firm with close links to Israeli intelligence. This development raises serious questions about data sovereignty, as sensitive health data may now be subject to foreign oversight and potential espionage vulnerabilities.
