@ManlingLi_ amazing!!!🎉🎈

We are looking for PhDs and Postdocs! So proud of my students on achieving so many amazing things during their "very first year". I have been asked many times how I like being faculty, especially with funding cuts. My answer is always "it is the prefect job for me"! Still deep in the honeymoon phase. The only reason is the students are so amazing, making my transition so much easier. One year in, they already collected paper awards, orals, spotlights, etc What makes me proudest is they are vividly alive: curious, playful, confident in their own weird way, light up when talking about ideas, and never afraid to explore "the thing might fail". Everyone is just… themselves. And somehow, that version of themselves keeps shipping amazing work. In today's anxious academic world, this kind of aliveness is what I will try best to protect. Maybe the best part of being an advisor is that every student is so different and unique lol Interestingly, coming to second year, they've got their own passions, I can't just plug my ideas into their heads. So when I get excited about sth new, my first thought is: "Okay, time to find some fresh first-years who will be thrilled about this!" MLL lab is 1 year old, we started right in Oct 2024. We are growing and looking for more phds to join us! 1. Why our lab? (1/2) 2. Why @northwesterncs? (2/2) In 2025 alone: NU has 7 faculty as Sloan Fellows, plus a Nobel winner! Check more below

This is Gemini 3: our most intelligent model that helps you learn, build and plan anything. It comes with state-of-the-art reasoning capabilities, world-leading multimodal understanding, and enables new agentic coding experiences. 🧵

After six wonderful years at UIUC @siebelschool, I’m thrilled to announce that I will join the University of Toronto ECE @eceuoft as an assistant professor in July 2026. I’m actively looking for PhD students in fall 2026. Drop me an email if you are interested in working with me.

Introducing MCPMark, a collaboration with @EvalSysOrg and @lobehub! We created a challenging benchmark to stress-test MCP use in comprehensive contexts. - 127 high-quality data samples created by experts. - GPT-5 takes the current lead and achieves a Pass@1 of 46.96% while the other models fall in the range of 10-30%. - Diverse test cases on Notion, Github, Filesystem, Playwright (browser), and Postgres. 9🧵s ahead

🚨 Incredibly excited to share that I'm starting my research group focusing on AI safety and alignment at the ELLIS Institute Tübingen and Max Planck Institute for Intelligent Systems in September 2025! 🚨 Hiring. I'm looking for multiple PhD students: both those able to start in Fall 2025 (i.e., as soon as possible) and through centralized programs like CLS, IMPRS, and ELLIS (the deadlines are in November) to start in Spring–Fall 2026. I'm also searching for postdocs, master's thesis students, and research interns. Fill the Google form below if you're interested! Research group. We will focus on developing algorithmic solutions to reduce harms from advanced general-purpose AI models. We're particularly interested in alignment of autonomous LLM agents, which are becoming increasingly capable and pose a variety of emerging risks. We're also interested in rigorous AI evaluations and informing the public about the risks and capabilities of frontier AI models. Additionally, we aim to advance our understanding of how AI models generalize, which is crucial for ensuring their steerability and reducing associated risks. For more information about research topics relevant to our group, please check the following documents: - International AI Safety Report, - An Approach to Technical AGI Safety and Security by DeepMind, - Open Philanthropy’s 2025 RFP for Technical AI Safety Research. Research style. We are not necessarily interested in getting X papers accepted at NeurIPS/ICML/ICLR. We are interested in making an impact: this can be papers (and NeurIPS/ICML/ICLR are great venues), but also open-source repositories, benchmarks, blog posts, even social media posts—literally anything that can be genuinely useful for other researchers and the general public. Broader vision. Current machine learning methods are fundamentally different from what they used to be pre-2022. The Bitter Lesson summarized and predicted this shift very well back in 2019: "general methods that leverage computation are ultimately the most effective". Taking this into account, we are only interested in studying methods that are general and scale with intelligence and compute. Everything that helps to advance their safety and alignment with societal values is relevant to us. We believe getting this—some may call it "AGI"—right is one of the most important challenges of our time. Join us on this journey!

Europe can lead AI research, and our plan with OpenEuroLLM is to build something amazing - not for profit, and while sharing insights at scale. We have openings for **ML Research Engineers and Scientists** to work on OpenEuroLLM at the ELLIS Institute Tübingen. ellis-openeurollm-apply.tue.mpg.de/registration/o…

I've struggled to announce this amidst so much dark & awful going on in the world, but with 1mo to go, I wanted to share that: (i) I finally graduated; (ii) In August, I'll begin as an assistant professor in the CS dept. of the National University of Singapore.

@niloofar_mire @CMU_EPP @LTIatCMU @AIatMeta @kamalikac Congrats!!

📣Thrilled to announce I’ll join Carnegie Mellon University (@CMU_EPP & @LTIatCMU) as an Assistant Professor starting Fall 2026! Until then, I’ll be a Research Scientist at @AIatMeta FAIR in SF, working with @kamalikac’s amazing team on privacy, security, and reasoning in LLMs!

We’ve raised $30M in Seed + Series A funding led by @lightspeedvp and Walden Catalyst Ventures, with participation from Prosperity7 Ventures, Factory, Osage University Partners (OUP), Lip-Bu Tan, Chris Re, and more. Virtue AI is the first unified platform for securing AI across red teaming, guardrails, and agents. We’re proud to already support forward-thinking companies like @Uber , @glean, and several frontier labs. This investment will help us continue improving our platform, scale agentic workflows, build out integrated enterprise use cases, and grow our team. Grateful to our customers, our team, and our investors for the support.

We build 𝗠𝗲𝗱𝗛𝗘𝗟𝗠✨: a comprehensive benchmark evaluating AI on realistic clinical tasks that healthcare professionals perform daily instead of just medical exams.👩‍⚕️⚕️ • Stanford HAI Blog: hai.stanford.edu/news/holistic-… • Leaderboard: crfm.stanford.edu/helm/medhelm/l…
