What if our world models are just as emergent and flimsy as AI’s?
I keep hearing that world models are the way forward for AI.
I tend to agree, and have been saying the same for many years as a technical person in AI but a non-A-tier-AI-researcher working on actual models.
Anyway, I’m up at 3:45AM today with an insane thought.
Why do we think humans have world models? — Read More

Building AI for cyber defenders
AI models are now useful for cybersecurity tasks in practice, not just theory. As research and experience demonstrated the utility of frontier AI as a tool for cyber attackers, we invested in improving Claude’s ability to help defenders detect, analyze, and remediate vulnerabilities in code and deployed systems. This work allowed Claude Sonnet 4.5 to match or eclipse Opus 4.1, our frontier model released only two months prior, in discovering code vulnerabilities and other cyber skills. Adopting and experimenting with AI will be key for defenders to keep pace.
We believe we are now at an inflection point for AI’s impact on cybersecurity.
For several years, our team has carefully tracked the cybersecurity-relevant capabilities of AI models. Initially, we found models to be not particularly powerful for advanced and meaningful capabilities. However, over the past year or so, we’ve noticed a shift. — Read More
AI Creation Tilly Norwood Isn’t an ‘Actress’ — So Don’t Call Her That
Let’s be frank: everyone thinks they can act. On a weekly basis, I have people ask me about “getting some voice over work for extra money” or doing a show “for fun.” And I have to wonder if any other industry is viewed this way. Do doctors have friends who suggest popping in for a quick organ transplant for kicks? Do relatives ask cops if they can borrow their gun and badge for a day? There’s a reason acting is so aspirational and yet so hard to succeed at.
When stories broke over the weekend about what people are calling the first AI-generated actress, Tilly Norwood, the response from Hollywood was so negative that one really had to wonder what the creators expected. In a time where the industry has been decimated by COVID, strikes and changing business models, who thought this would be celebrated? Celebrities from Kiersey Clemons to Melissa Barrera quickly weighed in, with the former noting: “How gross, read the room.” Perhaps Oscar-nominated actor Toni Collette said it best, when she posted the story with a series of screaming-face emojis. — Read More
