LLM Agents

What if your AI agent could remember the last time it made a mistake—and plan better this time? From Reaction to Reflection: Why Memory Matters Most language model agents today operate like goldfish—brilliant at reasoning in the moment, but forgetful. Whether navigating virtual environments, answering complex questions, or composing multi-step strategies, they often repeat past mistakes simply because they lack a memory of past episodes. That’s where the paper “Agentic Episodic Control” by Zhihan Xiong et al. introduces a critical upgrade to today’s LLM agents: a modular episodic memory system inspired by human cognition. Instead of treating each prompt as a blank slate, this framework allows agents to recall, adapt, and refine prior reasoning paths—without retraining the underlying model. ...

Introduction: From Reaction to Proaction Imagine an assistant that doesn’t wait for your command. It notices you’re standing by a bus stop late at night and proactively checks the next bus arrival. If it’s too far off, it suggests calling a ride instead. Welcome to the world of ContextAgent — a proactive, context-aware Large Language Model (LLM) agent designed to act before you’re forced to ask. While most LLM agents still require explicit prompts and work in tightly scoped environments like desktops, ContextAgent leverages open-world sensory inputs (from devices like smart glasses, earphones, and smartphones) to understand user context and offer unobtrusive help. ...

“You expect AI to be dumber than humans. But when it’s smarter and still fails, that’s when it hurts.” Earlier this month, Cursor AI’s chatbot “Sam” fabricated a nonexistent refund policy, confidently explaining to users why it was entitled to keep their subscription money—even when those users were eligible for a refund1. The backlash was immediate. Users lost trust. Some cancelled their subscriptions entirely. ...
