🚀 RAG systems excel at answering questions—but what happens when the corpus has NO answer or complex multi-hop reasoning is required? Moreover, how can we build benchmarks to stress-test RAG systems in such settings in a realistic way? See our new preprint to find out! 🧵👇

Bravo Kaili!
🎉 Delighted to announce that MetaFaith has been accepted to #EMNLP2025 Main! In this work we systematically study how well LLMs can express their internal uncertainty in words, offering a metacognition-inspired way to improve this ability 🧠✨ Check out more details below!👇

If you use "AI agents" (LLMs that call tools) you need to be aware of the Lethal Trifecta Any time you combine access to private data with exposure to untrusted content and the ability to externally communicate an attacker can trick the system into stealing your data!

Brett’s tweets are a great way to ride the pocket of AI
A ton of great progress in AI and Robotics this week. I summarized everything from Unitree, OpenAI, Mirror Me, Microsoft, Physical Intelligence, Luma, Sakana AI and more. Here's everything you need to know and how to make sense out of it:

📢The problem in model alignment no one talks about — the need for preference data, which costs $$$ and time! Enter Kahneman-Tversky Optimization (KTO), which matches or exceeds DPO without paired preferences. And with it, the largest-ever suite of feedback-aligned LLMs. 🧵

Congrats to everyone involved in one of the big announcements today! 🎉 To those who are not: remember that your value is NOT whether you find yourself in one of the few in-groups. A healthy scientific field is not supposed to make you feel left out. You are doing great 🌞

Imagine the power unleashed if we have GPT-3 inference-on-a-chip. But we won't get there based on digital circuits. The next great race may be for low-power analog chip designs that can incorporate weights directly into the inference circuit. buff.ly/3YOufLM

Reinforcement learning with human feedback is a promising technique that lets machines learn to understand human values. But let's not forget about its social & ethical implications. Read more: buff.ly/3L1iIpf  Original paper: buff.ly/3SU0Z4Z #AI #ethics #rlhf
