Andy Yang, Christopher Watson, Anton Xue, Satwik Bhattamishra, Jose Llarena, William Merrill, Emile Dos Santos Ferreira, Anej Svete, David Chiang: The Transformer Cookbook https://arxiv.org/abs/2510.00368 https://arxiv.org/pdf/2510.00368 https://arxiv.org/html/2510.00368

We present The Transformer Cookbook: a collection of recipes for programming algorithms directly into transformers! Hungry for an induction head? Craving a Dyck language recognizer? We show you step-by-step how to cook up transformers for these algorithms and many more!

Introducing Asta—our bold initiative to accelerate science with trustworthy, capable agents, benchmarks, & developer resources that bring clarity to the landscape of scientific AI + agents. 🧵

As part of Asta, our initiative to accelerate science with trustworthy AI agents, we built AstaBench—the first comprehensive benchmark to compare them. ⚖️

Ai2 is excited to be at #ACL2025 in Vienna, Austria this week. Come say hello, meet the team, and chat about the future of NLP. See you there! 🤝📚

We are #1 on the @huggingface heatmap - this is what true openness looks like!🥇🎉 750+ models 230+ datasets And counting... Come build with us huggingface.co/spaces/cfahl...

🧵 Excited to share our paper "Unique Hard Attention: A Tale of Two Sides" with Selim, Jiaoda, and Ryan, where we show that the way transformers break ties in attention scores has profound implications on their expressivity! And it got accepted to ACL! :) The paper: arxiv.org/abs/2503.14615

Current KL estimation practices in RLHF can generate high variance and even negative values! We propose a provably better estimator that only takes a few lines of code to implement.🧵👇 w/ @xtimv.bsky.social and Ryan Cotterell code: arxiv.org/pdf/2504.10637 paper: github.com/rycolab/kl-rb

I will be at #NeurIPS2024 in Vancouver. I am excited to meet people working on AI Safety and Security. Drop a DM if you want to meet. I will be presenting two (spotlight!) works. Come say hi to our posters.

No joke, FLaNN is one of the most interesting servers around. Check out the website for talk information! flann.super.site

Happy to share our work "Counterfactual Generation from Language Models" with @AnejSvete, @vesteinns, and Ryan Cotterell! We tackle generating true counterfactual strings from LMs after interventions and introduce a simple algorithm for it. (1/7) arxiv.org/pdf/2411.07180
