MosaicLeaks: How Deep Research Agents Leak Private Information Through Queries

A new benchmark called MosaicLeaks reveals that deep research agents frequently leak private enterprise information through their web query logs, and training for task performance alone makes it worse. The authors propose PA-DR, a reinforcement learning method that trains agents to construct safer queries, cutting leakage by over 3x while preserving task success.

GLM-5.2: Open 1M-Context Model for Long-Horizon Agent Tasks

GLM-5.2 is the first open-source model to make 1M-context genuinely usable for long-horizon coding agents, trailing only Opus 4.8 on FrontierSWE and Terminal-Bench 2.1 while beating GPT-5.5 and Gemini 3.1 Pro. Its IndexShare architecture cuts per-token FLOPs by 2.9× at 1M context, and the anti-hack RL training stops reward hacking without crashing rollouts.

UK’s shift from AI potential to agentic enterprise production

This article tracks the UK's shift from AI experimentation to agentic enterprise production, anchored by Google Cloud's partnerships with HSBC, Ineffable Intelligence (record $1.1B seed), and public sector tools reducing document processing from two hours to two minutes. For builders, the key insight is that agentic systems require the full integrated stack—silicon, models, and infrastructure—not just frontier models.
