If you're proofreading someone's draft, upload it to whatever LLM you have access to and just chat through the paper. Ask it questions and talk through your confusion. Then send the entire conversation to the author. That's actually good feedback.

"X is All You Need" title was great but I think we've earned the right to let it rest or just go all in with "All You Need is Whatever I'm Working On" honestly I would respect that more

If you’re a Brown student, locked down in your dorm or the OMAC, and scared and sad and exhausted and angry, know that there are over 100,000 alums around the world who are thinking of you and have your back.

RL for reasoning often rely on verifiers — great for math, but tricky for creative writing or open-ended research. Meet RARO: a new paradigm that teaches LLMs to reason via adversarial games instead of verification. No verifiers. No environments. Just demonstrations. 🧵👇
