Today at ICLR 2026: where does differential privacy actually start working on small tabular data? We mapped the boundary across six datasets. Sharp transition at N/d ≈ 50–300. DATA-FM Workshop, Rio. Come find me. #ICLR2026

Back from #EurIPS Copenhagen. The European AI "style" came up a lot, which is less about where research happens, more about how: rigour, efficiency, interpretability over pure scale. Hope it returns in 2026 (offset by a week so we can do NeurIPS Sydney too). Phrase of the conference: Pareto-front

Within two years, the largest data centers may use more power than major cities. We think Microsoft's Fairwater Wisconsin campus will have a peak electrical load of 3.3 GW when its fourth building comes online in late 2027. (Los Angeles used 2.4 GW on average in 2023)

Great conversations at Launch @ethz.ch today on what it takes to scale infrastructure plays in Europe. The speakers highlighted critical new challenges that startups face, especially around timing, market entry and what differentiates category-defining companies from point solutions.

Sora 2 can solve questions from LLM benchmarks, despite being a video model. We tested Sora 2 on a small subset of GPQA questions, and it scored 55%, compared to GPT-5’s score of 72%.

Those claiming there’s no energy transition only an “energy addition,” are wrong. I told FT: Yes, it’s correct that we are not on track globally to reduce emissions fast enough. But if you look at what’s happening across sectors, technologies, and geographies, you see real transitions underway.

My TV has a bug, either the video plays normally or the video progress bar shows, but never both simultaneously. I think it was designed by Heisenberg. I can observe either the plot or the position in the movie, but I can’t know both at once.

🧵 New paper from UK AISI x @eleutherai.bsky.social rai.bsky.social‬ that I led with @kyletokens.bsky.social y.social���: Open-weight LLM safety is both important & neglected. But filtering dual-use knowledge from pre-training data improves tamper resistance *>10x* over post-training baselines.
