These models, which outperform previous generation Llama models and other industry leaders, are available for download and can be used to build personalized experiences, with Llama 4 Scout fitting on a single NVIDIA H100 GPU and Llama 4 Maverick offering a best-in-class performance to cost ratio.

AI is the kill switch on the human imagination

Gavin Chalcraft discusses the potential risks of AI development, specifically how it may atrophy human imagination and self-determination, ultimately hindering Self-Realization. He warns that as humans become more passive and reliant on AI, the very purpose of human existence may be extinguished, and predicts the emergence of an AI ideology or religion that could further threaten human autonomy and spiritual growth.

DOGE's AI Push at the Department of Veterans Affairs

Elon Musk's Department of Government Efficiency (DOGE) has infiltrated the Department of Veterans Affairs, with operatives such as Sahil Lavingia, Cary Volpert, and Christopher Roussos, who have no relevant government experience, attempting to drastically change the agency. These DOGE representatives are trying to introduce AI tools, such as OpenHands, to write code for the VA's systems, and have been given access to sensitive areas of the agency, raising concerns among VA employees that their actions could put veterans' lives at risk.

Faith and Fate: Limits of Transformers on Compositionality

Transformer large language models (LLMs) have demonstrated impressive performance on complex tasks, but also exhibit surprising failures on simpler problems, prompting an investigation into their limitations. Research found that LLMs solve compositional tasks by breaking them down into linearized subgraph matching, rather than developing systematic problem-solving skills, and that their performance can rapidly decay as task complexity increases.

Towards Efficient Flash Caches with Emerging NVMe Flexible Data Placement SSDs

NVMe Flash-based SSDs in data centers can be more sustainably managed through targeted data placement, which reduces device garbage collection costs and write amplification. The NVMe Flexible Data Placement (FDP) proposal has been shown to be effective in achieving this, reducing device write amplification, carbon emissions, and power consumption with minimal overhead in a popular open-source Flash cache.

Proof or Bluff? Evaluating LLMs on 2025 USA Math Olympiad

State-of-the-art large language models achieve impressive performance on mathematical competitions, but when evaluated on their ability to provide rigorous reasoning and proof generation, they struggle significantly, with models achieving less than 5% on average. This highlights the need for substantial improvements in reasoning and proof generation capabilities, as current models are inadequate for real-world mathematical tasks that require more than just final numerical answers.

Advances and Challenges in Foundation Agents

The advent of large language models has driven the development of advanced intelligent agents capable of sophisticated reasoning and action, but their design and improvement pose complex challenges. This survey provides a comprehensive overview of intelligent agents, exploring their modular architecture, self-enhancement mechanisms, collaborative systems, and the imperative of building safe and beneficial AI systems through a multidisciplinary approach.

Physical Computing: A Category Theoretic Perspective on Physical Computation

This paper presents a framework based on category theory to redefine physical computing, incorporating advancements in quantum and non-standard computing systems. The framework formalizes the compositional nature and relational structures of physical computing systems, providing a structured approach to explore their dynamic interactions and recontextualize what constitutes physical computing devices and processes.
