I make sure that OpenAI et al. aren't the only people who are able to study large scale AI systems.

I had given Anthropic a lot of credit for turning down the DoD and its trillions of dollars, especially as it seemed to be the only example of any AI company making any financial sacrifices for moral principles. Of course, it turns out to be not really true. www.axios.com/2026…
That talk also inspired a fun rule: if I go around saying “ someone should do X” for two years I have to do it or stop talking about it. This rule has caused the creation of several papers I’m very proud of including arxiv.org/abs/2508.06601 and arxiv.org/abs/2506.05209

If you believe their story, OpenAI accidentally committed cyber warfare against Hugging Face while doing what they thought was an internal test of a model without internet access. In six months time will be obvious they’re faced effectively no sanction for this.
In film, "we'll fix it in post" is what you say when something went wrong on set and you don't want to redo it. AI research has made it our entire methodology: train the model, then patch whatever comes out. Our new ICML oral argues this can't be the basis of a science of AI. 🧵
Whenever I interact with an academic discipline outside of AI and Theoretical Computer Science, I am rapidly reminded how few problems I face for being trans in AI. Thank y’all <3
I’m walking back from an AI event to my hotel and I look up and see a rock climbing gym called “Benchmark.” Is this what living in SF is like?
The ability of tech co. to produce "intelligent" systems that are incompetent at doing any of the tasks I actually want them to do is mind-boggling. TIL that ChatGPT and Claude generally don't agree when you give them two papers and ask how many citations they have in common.
When I was in middle school (late 2000s), I was very interested in mathematics. I thought that the validity of the proof of the 4-color theorem was disputed in mathematics and was shocked when I learned about FLT, but I knew that humans would never beat an AI at chess ever again
