🚨 New Study 🚨

@arxiv.bsky.social has recently decided to prohibit any 'position' paper from being submitted to its CS servers.
Why? Because of the "AI slop", and allegedly higher ratios of LLM-generated content in review papers, compared to non-review papers.

Looking forward to learning new things in 2026?
We’ve got you covered with 17 amazing talks exploring how AI reshapes the way we work! Get your conference pass 380.- available until January 31

Front Conference Zurich is coming up soon! On Friday, February 27, an amazing group of speakers will explore how AI is reshaping the way we work, from creativity and product design to engineering and collaboration

🤩 Our lineup: frontconference.com/schedule

We're at #NeurIPS2025 with papers, posters, workshops, fireside chats, & talks across the conference. Come learn about our latest research + see live demos!

Olmo 3 is a fully open LLM Olmo is the LLM series from Ai2—the Allen institute for AI. Unlike most open weight models these are notable for including the full training data, training process and checkpoints along …

Olmo 3 is notable as a "fully open" LLM - all of the training data is published, plus complete details on how the training process was run. I tried out the 32B thinking model and the 7B instruct models, + thoughts on why transparent training data is so important simonwillison.net/2025/Nov/22/...

Olmo 3 is out! 🤩
I am particularly excited about Olmo 3 models' precise instruction following abilities and their good generalization performance on IFBench!
Lucky to have been a part of the Olmo journey for three iterations already.

Happy Halloween!

There’s plenty of evidence for political bias in LLMs, but very few evals reflect realistic LLM use cases — which is where bias actually matters.

IssueBench, our attempt to fix this, is accepted at TACL, and I will be at #EMNLP2025 next week to talk about it!

New results 🧵

I will be giving a talk at @eth-ai-center.bsky.social next week, on RLVR for verifiable instruction following, generalization, and reasoning! 📢
Join if you are in Zurich and interested in hearing about IFBench and our latest Olmo and Tülu works at @ai2.bsky.social

Title page of the paper: WUGNECTIVES: Novel Entity Inferences of Language Models from Discourse Connectives, with two figures at the bottom Left: Our figure 1 -- comparing previous work, which usually predicted the connective given the arguments (grounded in the world); our work flips this premise by getting models to use their knowledge of connectives to predict something about the world. Right: Our main results across 7 types of connective senses. Models are especially bad at Concession connectives.

"Although I hate leafy vegetables, I prefer daxes to blickets." Can you tell if daxes are leafy vegetables? LM's can't seem to! 📷

We investigate if LMs capture these inferences from connectives when they cannot rely on world knowledge.

New paper w/ Daniel, Will, @jessyjli.bsky.social

Next up we had @tsvetshop ‘s Yulia Tsvetkov talk about ethics, safety, and reliability of LLMs in the health domain.

💡We kicked off the SoLaR workshop at #COLM2025 with a great opinion talk by @michelleding.bsky.social & Jo Gasior Kavishe (joint work with @victorojewale.bsky.social and
@geomblog.bsky.social
) on "Testing LLMs in a sandbox isn't responsible. Focusing on community use and needs is."

Third Workshop on Socially Responsible Language Modelling Research (SoLaR) 2025 COLM 2025 in-person Workshop, October 10th at the Palais des Congrès in Montreal, Canada

Hi #COLM2025! 🇨🇦 I will be presenting a talk on the importance of community-driven LLM evaluations based on an opinion abstract I wrote with Jo Kavishe, @victorojewale.bsky.social and @geomblog.bsky.social tomorrow at 9:30am in 524b for solar-colm.github.io

Hope to see you there!

Now accepted to #neurips25 datasets & benchmarks!
See you in San Diego! 🥳

🚀 Can open science beat closed AI? Tülu 3 makes a powerful case. In our new #WiAIRpodcast, we speak with Valentina Pyatkin (@valentinapy.bsky.social) of @ai2.bsky.social and the University of Washington about a fully open post-training recipe—models, data, code, evals, and infra. #WomenInAI 1/8🧵

"𝐋𝐋𝐌 𝐏𝐨𝐬𝐭-𝐭𝐫𝐚𝐢𝐧𝐢𝐧𝐠: 𝐎𝐩𝐞𝐧 𝐒𝐜𝐢𝐞𝐧𝐜𝐞 𝐓𝐡𝐚𝐭 𝐏𝐨𝐰𝐞𝐫𝐬 𝐏𝐫𝐨𝐠𝐫𝐞𝐬𝐬 " 🎙️

On Sept 17, the #WiAIRpodcast speaks with @valentinapy.bsky.social (@ai2.bsky.social & University of Washington) about open science, post-training, mentorship, and visibility

With fresh support of $75M from NSF and $77M from NVIDIA, we’re set to scale our open model ecosystem, bolster the infrastructure behind it, and fast‑track reproducible AI research to unlock the next wave of scientific discovery. 💡

On my way to Oxford: Looking forward to speaking at OxML 2025

I had a lot of fun contemplating about memorization questions at the @l2m2workshop.bsky.social panel yesterday together with Niloofar Mireshghallah and Reza Shokri, moderated by
@pietrolesci.bsky.social who did a fantastic job!
#ACL2025

I'll be at #ACL2025🇦🇹!!
Would love to chat about all things pragmatics 🧠, redefining "helpfulness"🤔 and enabling better cross-cultural capabilities 🗺️ 🫶

Presenting our work on culturally offensive nonverbal gestures 👇
