What if AI agents aren't here to replace us, but to facilitate our decisions? In a study with 1600 participants, we show that a human with action choices narrowed by an AI makes better sequential decisions than an AI or a human alone. 📜 arxiv.org/abs/2510.16097

Decisions are out for EurIPS 2025 Workshops 🎉: eurips.cc/workshops As workshop chairs with Yingzhen Li @autreche.bsky.social and @witzner.bsky.social, we are excited to share the workshop program and look forward to seeing the community in December!

Last week I had the pleasure of presenting a 2.5-hour tutorial on "Counterfactuals in Minds and Machines" at UAI 2025 in Rio 🇧🇷, prepared together with @autreche.bsky.social and @tobigerstenberg.bsky.social. We've made all materials and references available here: learning.mpi-sws.org/counterfactu...

EurIPS includes a call for both Workshops and Affinity Workshops! We look forward to making #EurIPS a diverse and inclusive event with you. The submission deadlines are August 22nd, AoE. More information at: eurips.cc/call-for-wor... eurips.cc/call-for-aff...

📣 Life update: Thrilled to announce that I’ll be starting as faculty at the Max Planck Institute for Software Systems this Fall! I’ll be recruiting PhD students in the upcoming cycle, as well as research interns throughout the year: lasharavichander.github.io/contact.html

In Athens 🇬🇷 for the Greeks in AI symposium. Super excited to present our work on "Counterfactual Token Generation in LLMs" (bit.ly/4nMibs2) and see all the amazing work Greek people all over the world are doing on AI! If you are in Athens, let's meet! Next, heading to👇

Heading to Rio de Janeiro 🇧🇷 for UAI 2025 (@auai.org) to present our tutorial with @tobigerstenberg.bsky.social and @autreche.bsky.social on "Counterfactuals in Minds and Machines" on Monday. Looking forward to this! If you are in Rio, let's meet!

The LLM API you use returns (and charges you for) 5 tokens. Did the LLM actually generate 5 tokens? Or is the provider overcharging you? 🤔 In arxiv.org/abs/2505.21627, led by Ander Artola Velasco, we argue (game-theoretically) for a change from pay-per-token to pay-per-character.

In Singapore for #ICLR2025! I'll be presenting our work on a causal methodology for evaluating LLMs (arxiv.org/abs/2502.01754) at the "Building Trust in LLMs" workshop on Monday. If you are working on causality, game theory and/or LLMs, let's grab a ☕️ during the conference!

The NeurIPS Call for Workshops is now live. Proposals are due May 30 AoE, with acceptance notification on July 4 AoE. neurips.cc/Conferences/...
 If you plan to submit a proposal for a workshop, please read our detailed guidance in our new blog post: blog.neurips.cc/2025/04/12/g...

Together with @autreche.bsky.social, Adish Singla, Krishna Gummadi, Goran Radanovic and Nina Grgić-Hlača, we have multiple open positions postdocs in AI, Computing, and Society at the MPI for Software Systems! Apply by May 13 via the new Max Planck Postdoc Program! www.mpg.de/en/max-planc...

In “AI for modelling infectious disease epidemics”, just published in Nature, we discuss how AI can help us in future pandemics. This is joint work with many colleagues, led by Moritz U G Kraemer and Samir Bhatt! www.nature.com/articles/s41... You can read it for free here: t.co/s4YjjmTNOp

Obama, speaking in October 2016: "Government will never run the way Silicon Valley runs because, by definition, democracy is messy. And part of government's job, by the way, is dealing with problems that nobody else wants to deal with." 1/6 youtu.be/BikQFWNYct4?...

LLMs rely on randomization to respond to a prompt: they may respond differently to the same prompt if asked multiple times. In “Evaluation of LLMs via Coupled Token Generation” (arxiv.org/abs/2502.01754), we argue that the eval of LLMs should control for this randomization 1/

The FATE group at @msftresearch.bsky.social NYC is accepting applications for 2025 interns. 🥳🎉 For full consideration, apply by 12/18. jobs.careers.microsoft.com/global/en/jo... Interested in AI evaluation? Apply for the STAC internship too! jobs.careers.microsoft.com/global/en/jo...

Very excited and grateful to receive an ERC Consolidator grant #ERCCoG on Counterfactuals in Minds and Machines! Are you interested in a postdoc or Ph.D.? Please get in touch by email!

What would an LLM have said, counterfactually? Here is a short video illustrating our method for counterfactual token generation. We will present this work at the CaLM workshop at #neurips2024. See you in Vancouver! 📜 arxiv.org/abs/2409.17027 💻 made with manim in python

Tenure-track openings at MPIs in all areas of CS and its intersection with other discipline, deadline Dec 1st. I cannot think of better positions in Europe for young researchers who want to start a group! Ping me if you want to hear my personal experience! apply.cis.mpg.de/register/ttf...
