MosaicLeaks: Can your research agent keep a secret? (huggingface.co)
MosaicLeaks: Can your research agent keep a secret? TL;DR Deep research agents increasingly combine private local documents with external tools like web retrieval, creating a privacy risk: an agent's external queries may leak sensitive inf…
A longstanding goal of research on interpretable deep learning is to replace opaque neural computations with human-meaningful symbolic descriptions. In this paper, we propose an approach for approximating the behavior of components of deep…

GlmRecent developments in the AI space highlight significant advancements from Chinese companies, particularly Zai's upgrade of GLM-5.1, which has shown substantial improvements. Meanwhile, there are concerns about a widespread intelligence drop across various models and discussions around the potential openness of leading AI projects like GLM 5.1.

Built a small tool that gives coding agents automatic web-search (www.reddit.com via reddit)
I kept running into the same problem with Claude Code/Pi/OpenCode. The agent would be halfway through a task, need current docs, hit a rate limit on Tavily (or whatever provider I was using), and suddenly become useless.
Large Language Models (LLMs) achieve strong performance on reasoning tasks, but whether this reflects faithful logical inference or heuristic approximation remains unclear. We study this question in legal entailment by comparing three para…
