We benchmarked several open-weight Chinese models on FrontierMath. Their top scores on Tiers 1-3 lag the overall frontier by about seven months.

🚀 Big time! We can finally do simple LLM RL fine-tuning with rewards and leverage offline/off-policy data!

❌ You want rewards, but GRPO only works online?
❌ You want offline, but DPO is limited to preferences?
✅ QRPO can do both!

🧵Here's how we do it:

We provide an efficient and performant method that provides best of both worlds in a new architecture. We managed to show that our approach scales better than the SOTA transformers with self-attention.

Incredible execution and attention to details by @xiuyingwei.bsky.social !

Thrilled to announce that our work “Fleet of Agents” has been accepted @icmlconf.bsky.social. On average, FoA boosts quality by ~5% while reducing costs to ~40% of SOTA baselines. Blog post after the Neurips deadline ;)

Until then:

Excited to share our latest work on EvoTune, a novel method integrating LLM-guided evolutionary search and reinforcement learning to accelerate the discovery of algorithms! 1/12🧵

This fantastic work is mainly due to incredibly hard-working students like @anjasurina.bsky.social, @lars-quaedvlieg.bsky.social, and Amin Mansouri. Also, this was my first paper with a Fields medalist, Maryna Viazovska, and the one and only Emmanuel Abbe 😀.

Wohoo🥳 Thrilled to announce this paper 📢. We have shown that it is possible to significantly improve the FunSearch method with RL and achieve impressive algorithmic discoveries on challenging NP-complete combinatorial optimization tasks like TSP and bin-packing.

Ahahaha it is still very clear in my as if it was yesterday and it was definitely soju because after you talked with the owner; several plastic bottles of soju showed up on our table. Though I don't remember the rest of night 😉

If it turns out LLMs are only capable of recombinatory innovation (finding novel connections among existing knowledge), that would still be very useful. Most innovation is recombination and one of the big issues in science is that fields are too vast for scientists to bridge them to find connections

Amazing, could become the next hit 😉 I discovered @kyunghyuncho.bsky.social's amazing singing skills when I first went to karaoke with him in 2012.

TURING AWARD WINNER Richard S. Sutton in Conversation with Cam Linke | No Authorities in Science YouTube video by Amii

www.youtube.com/watch?v=9_Pe... An interview with Rich. The humility of Rich is truly inspiring: "There are no authorities in science". I wish people would listen and live by this.

stay tuned for more proper, detailed and exciting cover of this preprint, but whoa i'm so proud of the team @prescientdesign.bsky.social and our achievements on <Lab-in-the-loop therapeutic antibody design with deep learning>!

And I am an ally. If you are too, let the world know.

I have been using Glove80 kb in the last week due to my RSI and it improved significantly since then. But I am still baffled how hard it is to get used to a new kb layout. Oddly, although I type perfectly fine on it now, I can't enter my passwords with it because they are stored in my muscle memory.

LLMs and World Models, Part 1 How do Large Language Models Make Sense of Their “Worlds”?

Do large language models develop "emergent" models of the world? My latest Substack posts explore this claim and more generally the nature of "world models":

Trajan's (@starlord37.bsky.social) story & countless others like it in the face of these cuts and wild shifts in government fellowships intended for our brightest & most promising students will have long-term, deeply damaging effects on the U.S.'s competitiveness in science, math, CS and more.

We’ve been thrilled by the positive reception to Gemini 2.0 Flash Thinking we discussed in December.

Today we’re sharing an experimental update w/improved performance on math, science, and multimodal reasoning benchmarks 📈:
• AIME: 73.3%
• GPQA: 74.2%
• MMMU: 75.4%
