Hierarchical Agents Don't Know Who They're Talking To
Roughly 70% of Earth science datasets hosted in large repositories like PANGAEA go uncited after publication. The data exists. The agents can access it....
When Your Agent Stops Using Tools
Reinforcement learning was supposed to teach agents to use tools fluently. Instead, researchers are watching a consistent failure mode: models trained...
The Protocol Wars Are Ending. Here's What Actually Happened.
Anthropic's MCP and Google's A2A joined the Linux Foundation. IBM killed its own protocol to back A2A. 146 organizations signed on. The wars are ending.
Multi-Agent Reasoning's Memory Problem
Reasoning language models score in the top percentile on math olympiad benchmarks, yet a new study from Stanford found they fail to correctly recall their...
Nobody Knows If Deployed AI Agents Are Safe
The 2025 AI Agent Index just cataloged over 100 deployed agentic AI systems, and the finding that should alarm everyone isn't about capability. It's about...
Small Models Just Learned When to Ask for Help
SWE-bench has been the graveyard of small language models. While GPT-4 class systems resolve over 40% of real-world GitHub issues, models under 10 billion...
The Control Interface Problem in Physical AI
NVIDIA just released a video foundation model that can simulate physical worlds with startling accuracy. A team at Oak Ridge National Laboratory built an...
Knowledge Graphs Just Made RAG Worth the Complexity
Retrieval-augmented generation was supposed to solve the hallucination problem. It didn't. Most RAG systems still return the wrong chunk, miss the...
Your Multi-Agent System Is Colliding
Most production agent systems don't fail because individual agents are stupid. They fail because three agents tried to solve the same problem...
Config Files Are Now Your Security Surface
Agentic coding assistants went from autocomplete to autonomous operators in under two years. Now they're editing production code, filing pull requests,...
