Here’s what I’ve been working on recently: @anthropicai. I’ll be spending a lot of my time on measurement and assessment of our AI systems, as well as thinking of ways govs/others can assess AI tech. There’s a lot to do!
New Anthropic report: Build AI in America. We outline what it will take to ensure America has the energy and infrastructure it needs to maintain its leadership in AI.
Showed my kid kites for, literally, the first time in their life. The most amazing part of being a parent is getting to experience things anew.

All hail Claudius, an instance of Sonnet 3.7 which has been running a business inside @AnthropicAI for a while. Claudius is the 'idiot in a fridge' precursor to 'a country of geniuses in a datacenter'.
We all know vending machines are automated, but what if we allowed an AI to run the entire business: setting prices, ordering inventory, responding to customer requests, and so on? In collaboration with @andonlabs, we did just that. Read the post: anthropic.com/research/proje…
After Chernobyl, global nuclear power growth rates slowed 10x. This is something that frontier AI labs, who are currently far below Chernobyl-level control of their products, should worry deeply about. The only path to lasting growth, is safety-led growth
As I said in my testimony yesterday, we have a short window of time to get a sensible federal policy framework in place before an accident or a misuse leads to a reactive and likely bad regulatory response.
Anthropic's @jackclarkSF notes that the clock is ticking: "We believe that extremely powerful systems are going to be built in, you know, the coming 18 months or so. End of 2026 is when we expect truly transformative technology to arrive. There must be a federal solution here."
