BountyBench: Dollar Impact of AI Agent Attackers and Defenders on Real-World Cybersecurity Systems

Anthropic has acquired Bun, a JavaScript and TypeScript runtime, enhancing the infrastructure behind its coding tool, Claude Code, which has achieved a $1 billion annual recurring revenue (ARR). This acquisition is expected to solidify the performance and efficiency of both Claude Code and the Claude Agent SDK, which already utilize Bun's capabilities.

Large language models (LLMs) have revolutionized software development by translating natural language into functional code, with tools like Github Copilot and Claude Code leading the charge. A recent comprehensive guide details the lifecycle of code LLMs, from data curation to autonomous coding agents, highlighting the significant advancements in performance metrics.

Recent research highlights the challenges of pruning reasoning language models (RLMs) like OpenAI's o1 and DeepSeek-R1, which are crucial for multi-step reasoning tasks. The study reveals that traditional pruning methods can severely impair the accuracy and coherence of these models, even at moderate levels of sparsity.

The introduction of SeeNav-Agent marks a significant advancement in Vision-Language Navigation (VLN) by addressing common errors in perception, reasoning, and planning that hinder navigation performance. This framework incorporates a dual-view Visual Prompt technique to enhance spatial understanding and a novel step-level Reinforcement Fine-Tuning method, Step Reward Group Policy Optimization (SRGPO), to improve navigation task rewards.

The study introduces PARROT (Persuasion and Agreement Robustness Rating of Output Truth), a framework aimed at assessing the accuracy degradation in large language models (LLMs) under social pressures, particularly focusing on sycophancy. It employs a double-blind evaluation to compare responses to neutral and authoritatively false questions, quantifying shifts in confidence and classifying various failure modes across 22 models using 1,302 questions from multiple domains.
