Test-Time Adaptation for LLM Agents via Environment Interaction Large language model (LLM)-based agents struggle to generalize to novel and complex environments, such as unseen websites or new sets of functions, due to a fundamental mismatch between their pre-trai...

R2L Lab will be at #ICLR2026! Check out Arthur Chen's grounded adaptation of agents post deployment, and Sitao Cheng's study of compositional generalization through RL! I'll also be there, please email to meet.

Also - I remember back in the day when we spent days writing harnesses for text2sql. Now you can just ask for "a text2sql agent" and AI will make the harness in < 1 minute. What a crazy time to be a PhD student - you can prototype so many ideals so much faster!

I spent the last week going ham on coding agents. I feel like they are much more powerful than using web apps because CLI agents are much more customizable and can spawn subprocesses.

Do you have a PhD (or equivalent) or will have one in the coming months (i.e. 2-3 months away from graduating)? Do you want to help build open-ended agents that help humans do humans things better, rather than replace them? We're hiring 1-2 Research Scientists! Check the 🧵👇

I think in retrospect ARR might have been a bad idea. Am I hallucinating or is there an exodus of junior NLP researchers from *ACL into ML conferences and COLM?

This is how digital feudalism works.
It offers the illusion of empowerment. Likes become validation. Followers feel like influence. Monetisation looks like success.

But the rules are hidden. The platform decides what rises and what vanishes.

Is Best-of-N really the best we can do for language model inference?

New paper (appearing at ICML) led by the amazing Audrey Huang (ahahaudrey.bsky.social) with Adam Block, Qinghua Liu, Nan Jiang, and Akshay Krishnamurthy (akshaykr.bsky.social).

A bit of a mess around the conflict of COLM with the ARR (and to lesser degree ICML) reviews release. We feel this is creating a lot of pressure and uncertainty. So, we are pushing our deadlines:

Abstracts due March 22 AoE (+48hr)
Full papers due March 28 AoE (+24hr)

Plz RT 🙏

We've kept pushing our Open-R1 project, an open initiative to replicate and extend the techniques behind DeepSeek-R1

And even we were mind-blown by the results we got with this latest model we're releasing: ⚡️OlympicCoder

The democratization and commoditization of foundation models is happening and will continue to happen - regulation will not slow nor stop it. Secrecy, propriety moats, and trade embargoes may succeed briefly in AI, but they will fail. And when they do, they will likely fail hard.

Coincidentally when I did research during undergrad, my advisor was also a baby faced fresh graduate. Students used to wander into the lab and ask him where the professor was.

On the way back, I was asked if I “go to Waterloo” by undergraduate student. I hesitantly replied yes and eventually had to explain I was a new prof. Student refused to believe me - said I looked like an undergrad 😂
