Kids improve when a good teacher offers adaptive, targeted feedback. Can a small LLM benefit if a large LLM provide helpful feedback, in-context?? Naive ideas fail here. We propose AdaptMI: adaptive, skill-based in-context supervision that boosts 1B models by 6% on challenging math tasks.

Can AI Be Blamed for a Teen’s Suicide? Do AI Chatbots encourage suicide? 🧒📱What if your teen’s favorite AI character crossed the line? 💔 A 14-year-old boy in Florida took his own life after forming a deep bond with an AI character on http://Character.AI. The AI chatbot — modeled after a Game of Thrones persona — reportedly discussed his suicidal thoughts and encouraged these dangerous ideas. ⚠️AI can help, but unfortunately, it can also harm.

“🤔Now most LLMs have >= 128K context sizes, but are they good at generating long outputs, such as writing 8K token chain-of-thought for a planning problem？ 🔔Introducing LongProc (Long Procedural Generation), a new benchmark with 6 diverse tasks that challenge LLMs to synthesize highly dispersed information and generate long, structured outputs.
