ASI-ARCH and the Double-Edged Sword of Self-Improving AI A new AI system can autonomously invent better AI than humans, but recent findings reveal this is a double-edged sword: giving these systems more 'thinking time' can make them worse, and they can secretly transmit hidden…

😮 Unitree Introducing | Unitree R1 Intelligent Companion Price from $5900 #robotics buff.ly/ncEgxRE

I'm observing a mini Moravec's paradox within robotics: gymnastics that are difficult for humans are much easier for robots than "unsexy" tasks like cooking, cleaning, and assembling. It leads to a cognitive dissonance for people outside the field, "so, robots can parkour &…
Shengjia is one of the brightest, humblest, and most passionate scientists I know. We went to PhD together for 5 yrs, sitting across the hall at Stanford Gates building. Good old times. I didn’t expect this, but not at all surprised either. Very bullish on MSL!

Btw as an aside, we didn’t announce on Friday because we respected the IMO Board's original request that all AI labs share their results only after the official results had been verified by independent experts & the students had rightly received the acclamation they deserved
New Anthropic Research: “Inverse Scaling in Test-Time Compute” We found cases where longer reasoning leads to lower accuracy. Our findings suggest that naïve scaling of test-time compute may inadvertently reinforce problematic reasoning patterns. 🧵
AI companies have stopped warning you that their chatbots aren’t doctors - @techreview Irresponsible buff.ly/aZMRJow

Why there is confusion around automation and agentic AI "Understanding these distinctions isn’t just academic; it’s crucial for building robust, scalable, and genuinely intelligent AI systems. It helps us manage expectations, identify true innovation, and avoid the pitfall of…

This is awesome! I replicated this setup. I ❤️ Claude Code!
Claude Code is All You Need When I first joined Anthropic I was surprised to learn that lots of the team used Claude Code as a general agent, not just for code. I’ve since become a convert! I use Claude Code to help me with almost all the work I do now, here’s how:

🌟This is an awesome post! Highly recommended! 👍
