LLM Agents Keep Getting Stuck. Giving Them Memory and Learning Fixed That. TL;DR — A new training approach lets AI agents both remember past attempts and learn from them simultaneously, leading to 2x better performance on complex tasks and the ability to tackle new problems without retraining. What It Is

Why Your LLM Goes Crazy During Training (And How 0.01% of Tokens Are to Blame) TL;DR — When training language models with reinforcement learning, about 1 in 10,000 tokens get wildly oversized updates that destabilize everything. Masking just these troublemakers fixes the problem. What It Is Researchers at
