Can a model learn to break its own reasoning plateau? In our new paper, we show that LLMs can be taught with meta-RL to generate their own "stepping stones" that kickstart learning on hard math problems (0/128 success rate) where direct RL fails.

📢 CfP for the 2nd version of MOSS at @COLM_conf! sites.google.com/view/moss-colm… (Deadline: 6/30) We welcome submissions on small-scale research for algorithmic innovation and scientific understanding across training, architecture, data, evaluation, interpretability, safety, and more!


Our team at @AIatMeta is excited to announce ATLAS: one of the largest automated formalization efforts to date. ATLAS contains Lean 4 formalizations of both statements and proofs from 25+ mathematics textbooks, spanning dozens of domains, for a total of 500k lines of code. We are also releasing a flexible formalization harness and a companion paper. External contributions are welcome! Joint work spearheaded by our amazing PhD student Ahmad Rammal (@Ahmad3Rammal), together with Niket Patel (@niketnpatel ), Fabian Gloeckle (@FabianGloeckle), Amaury Hayat (@Amaury_Hayat), Remi Munos (@MunosRemi), Julia Kempe (@KempeLab), Vivien Cabannes, and myself from @AIatMeta, @NYUDataScience , and Ecole des Ponts. This is an ongoing effort; more details in the thread below. (1/9)










Funny how people complain that the new arXiv policy is too harsh. If anything, it's still way too lenient. Getting caught with AI slop should result in a permanent, publicly viewable (in the form of a hall of shame) ban and retroactive redaction of all previous arXiv submissions.
