In my first year of my PhD, I measured progress by papers. The count was zero. I felt like an imposter with no sense of progress. That was an illusion - I was measuring the wrong thing. I see this happening frequently, so I wrote a post with what a learned. URL below.

Check out our latest work arxiv.org/abs/2601.21839, where we show the way @OpenAI, @AnthropicAI and others charge users for using their reasoning models incentivize them to increase test-time computations even if they contribute little to the quality of the outputs.

Done with #ICML2026? Setting up experiments for a new project can be boring... Here is a template that automates parameter configs, output filenames, SLURM etc. Works for me, hope it works for you! github.com/stsirtsis/rese… P.S. Templates are greener than AI coding agents🌱

The serious aspect here is that having a paper at NeurIPS can significantly boost a young researcher's career. As a sign of respect to authors who actually cared about the content of their papers yet got rejected, @NeurIPSConf needs to withdraw papers with hallucinated content.
Alex Cui@alexcdot

Okay so, we just found that over 50 papers published at @Neurips 2025 have AI hallucinations I don't think people realize how bad the slop is right now It's not just that researchers from @GoogleDeepMind, @Meta, @MIT, @Cambridge_Uni are using AI - they allowed LLMs to generate hallucinations in their papers and didn't notice at all. It's insane that these made it through peer review👇

Our decision support system is underpinned by a single parameter (epsilon) that adaptively controls the level of human agency. The resulting cumulative reward varies smoothly with epsilon, which allows us to find the optimal level of human agency using a bandit algorithm.

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

While I’m sad to leave @mpi_sws_ and its people, it's time to move on. Starting October, I will be a postdoctoral researcher at @HPI_DE, working with @SandraWachter5. Super excited about this next chapter!

@thegautamkamath *as long as they don't come with an unreasonable score, strong opinions, and overall bad vibes. We need more positivity in ML 🙂

The highest value and quality reviews are those which are very annoying and you hate, but then you begrudgingly admit that they are correct and do the things they suggest.

I'm so excited to be joining @Penn as an Assistant Professor in CS (@CIS_Penn) in Fall 2026! I’ll be working on machine learning ecosystems, aiming to steer how multi-agent interactions shape performance trends and societal outcomes. I’ll be recruiting PhD students this cycle!
