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

#IPAM (the institute for pure and applied mathematics) is facing a critical shortfall for operating expenses due to an unexpected suspension of NSF funding www.ipam.ucla.edu/news/nsf-fun... . Donations for emergency continuity of operations funding can be made at

πŸš€ 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?
βœ… 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 β€œFleet 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:

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 πŸ˜€.

WohooπŸ₯³ Thrilled to announce this paper πŸ“’. 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.

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

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 β€œWorlds”?

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.
