Meta Permits Its A.I. Models to Be Used for U.S. Military Purposes
Meta is shifting its policy to allow U.S. government agencies and contractors working on national security to use its artificial intelligence models for military purposes, despite its previous policy prohibiting such use. The company will make its open-source A.I. models, called Llama, available to federal agencies and is working with defense contractors and tech companies to support "responsible and ethical" innovations.
Perplexity CEO offers AI company's services to replace striking NYT staff
Perplexity CEO Aravind Srinivas has offered to provide his company's services to the New York Times to mitigate the effects of a strike by the NYT Tech Guild, which represents tech workers who provide software support and data analysis for the Times. Srinivas' offer was met with criticism on social media, with many accusing him of acting as a scab and undermining the collective action of the striking workers.
How a Mumbai Drugmaker Is Helping Putin Get Nvidia AI Chips
An Indian pharmaceutical company, Shreya Life Sciences, is selling top-end Dell servers optimized for artificial intelligence to Russia, which are equipped with Nvidia AI chips. This trade has raised concerns among the US and its European allies, as it appears to be a way for Russia to circumvent sanctions and obtain advanced technology.

Accuracy-Performance Trade-Offs in LLM Quantization
Researchers conducted a comprehensive study on the accuracy and performance of large language models using various quantization formats, including FP8, INT8, and INT4. The study found that certain formats, such as FP8 and INT8, can achieve high accuracy with minimal degradation, while others, like INT4, offer competitive performance and cost-efficiency in specific deployment environments.
MarsCode Agent: AI-Native Automated Bug Fixing
MarsCode Agent is a novel framework that uses large language models and advanced code analysis to automatically identify and repair bugs in software code. The framework has shown a high success rate in bug fixing compared to existing approaches, as demonstrated by its evaluation on a comprehensive benchmark of real-world software projects.
An embarrassingly simple approach to recover unlearned knowledge for LLMs
Large language models (LLMs) can acquire unwanted behaviors from their training data, and machine unlearning has been proposed as a solution to remove this problematic content. However, research has found that applying quantization to models that have undergone unlearning can restore the supposedly "forgotten" information, with up to 83% of the intended forgotten knowledge retained after 4-bit quantization.
Designing a Home Radio Telescope for 21 Cm Emission
This study outlines a cost-efficient method for creating a radio astronomy telescope to detect 21 cm emissions from neutral hydrogen in the Milky Way, allowing for the measurement of hydrogen cloud velocities and their roles in the galaxy's dynamics. The setup, designed for accessibility, uses a parabolic dish, a low-noise amplifier, a software-defined radio, and a Raspberry Pi, and includes techniques for mitigating radio frequency interference in urban environments.
Public Dataset of Social Media Discourse about the 2024 U.S. Election
Researchers have created a large-scale dataset of 22 million Twitter posts related to the 2024 U.S. Presidential Election, collected from May to July 2024 using a custom-built scraper. The dataset aims to provide a foundation for studying the influence of social media on political discourse, the spread of misinformation, and election-related narratives.
