I stopped using Google Analytics on my site almost 10 years ago because I didn't want to contribute to even more cookie-based tracking. Over the weekend, I used a Claude loop to set up self-hosted, cookieless analytics and I'm...pleasantly surprised that it worked so well.

In 2019 it took 6 months for GPT-2 to go from too-dangerous to release. Claude Mythos/Fable ran that cycle in 2 months. The AI PR singularity is amongst us. In 2029, there will be zero latency between a company saying a model is too dangerous and it being released.

Excited to share that our paper has been accepted to 𝗜𝗖𝗠𝗟 𝟮𝟬𝟮𝟲! 🎉 Multi-agent is everywhere today. But put frontier LLMs in a room where each holds a different piece of the puzzle, and they fail 70% of the time. Here's why: 📄 Paper: arxiv.org/abs/2505.11556

Systematic Failures in Collective Reasoning under Distributed Information in Multi-Agent LLMs

Multi-agent systems built on large language models (LLMs) are expected to enhance decision-making by pooling distributed information, yet systematically evaluating this capability has remained challen...

When was the last time you read a paper end-to-end for non-reviewing purposes? Seems like we write more than ever and read less than ever. (I'm guilty too) GenAI tools are kind of like a ddos attack on our attention. Far too much being produced to handle and justify consuming.

Excited to be heading to Barcelona for #CHI2026 to host our workshop PoliSim: LLM Agent Simulation for Policy! This year, we’ve seen incredible interest from researchers across HCI, NLP, CSS, and Policy. We accepted 25 outstanding papers, with 5 selected as Best Paper nominees.

The overleaf git project for one of my #uist2026 submissions was assigned a uuid starting with "67". I believe this lets me mine the latest block on the gen alpha blockchain using the "Proof of Relevance" protocol. Who should I speak with about this

Really excited that “Privy” received a CHI ’26 Honorable Mention Award 🏅 Privy is part of my PhD work on AI privacy: understanding AI privacy risks, studying why they’re hard to address in practice, and building tools that help product teams act on them.

📣 New at #CHI2026 Developing a new AI product? How would you figure out what are the privacy risks? Privy help non-privacy expert practitioners create high quality privacy impact assessments for early-stage AI products. Led by @hankhplee.bsky.social Paper: www.sauvik.me/papers/69/s...

I am working on a UX audit agent for my company (fuguux.com/). I passed in the output of our audit agent into Claude code for my personal website and...voila, a refreshed and much better site. Surprised it worked! Before -> after sauvik.me

SCOOP: An internal DHS document obtained by 404 Media shows for the first time CBP used location data sourced from the online advertising industry to track phone locations. This surveillance can happen through all sorts of apps, such as video games, news apps, weather trackers, and dating apps.

🚨New paper🚨 We spent a year working with emergency preparedness policymakers to answer a simple question: can LLM agent simulations actually help real institutions make better decisions? The answer is yes—but perhaps not how you'd expect. 👇 THREAD 👇 [Link to paper: arxiv.org/abs/2509.218... [1/n]

I'm fortunate to be able to teach my new class on "Building Technologies for the Resistance" next semester. If you're a CMU student, consider enrolling! This will be a collaborative, project-based class where you'll get to prototype resistance technologies.

I am pleased to say that I submitted the last of my dissertation work for publication! This work was a long-term goal starting with a Mozilla grant I applied for in my first year of PhD. Since then, I’ve learned a lot and hope that what I contributed will be useful to the community.
