Is Claude Code a threat to Clay? Here’s why I think, for now, that answer is no. And most (almost all) of my business is now Claude Code. And I designed it that way because it’s what I enjoy, not because it’s the best tool for every GTM problem.

Can natural language replace scalar rewards in reinforcement learning? A new paper from researchers at Stanford, UMD, Netflix, and Microsoft Research presents a formal structure for utilizing natural language as feedback in a reinforcement learning setting they call Learning from Language...

This little-known Chinese AI lab just dropped an AI model 3x faster and 20x cheaper than Claude. Here’s what the headlines won’t tell you:

I appreciate this reflection on why ARC matters, but in the replies I expressed some reservations about what high accuracy on ARC benchmarks actually reflects for assessing "human-like fluid intelligence" (Chollet's stated goal for ARC).

Agentic AI isn’t about learning 10 steps. It’s about mastering 4 loops: Perception → Memory → Planning → Action. Frameworks change. Autonomy principles don’t. Build agents that think in systems, not prompts. https://t.co/yINTc7aLJZ
