  • A Mike's-Eye View of ARC's Research

    Over the past 15 months or so, ARC's technical agenda has developed quite a bit. The advent of the Matching Sampling Principle (MSP), and ideas like it, has begotten a host of concrete technical problems; progress on those problems has given us more philosophical clarity on the big

  • Announcing the ARC White-Box Estimation Challenge

    ARC has teamed up with AIcrowd to launch the ARC White-Box Estimation Challenge, a contest to improve upon our estimation algorithms for random MLPs. The warm-up round begins this week, and later rounds will have a total prize pool of at least $100,000. We are very

  • Mechanistic estimation for expectations of random products

    We have developed some relatively general methods for mechanistic estimation competitive with sampling by studying problems that are expressible as expectations of random products.

  • Competing with sampling

    In 2025, ARC has been making conceptual and theoretical progress at the fastest pace that I've seen since I first interned in 2022. Most of this progress has come about because of a re-orientation around a more specific goal: outperforming random sampling when it comes to understanding

  • Obstacles in ARC's research agenda

    Former ARC researcher David Matolcsi has put together a sequence of posts that explores ARC's big-picture vision for our research and examines several obstacles that we face. We think these posts will be useful to readers who are interested in digging into the details of our big-

  • A computational no-coincidence principle

    In a recent paper in Annals of Mathematics and Philosophy, Fields medalist Timothy Gowers asks why mathematicians sometimes believe that unproved statements are likely to be true.

  • A bird's eye view of ARC's research

    Over the last few months, ARC has released a number of pieces of research. While some of these can be independently motivated, there is also a more unified research vision behind them. The purpose of this post is to try to convey some of that vision and how our individual

  • Low Probability Estimation in Language Models

    ARC recently released our first empirical paper: Estimating the Probabilities of Rare Language Model Outputs. In this work, we construct a simple setting for low probability estimation — single-token argmax sampling in transformers — and use it to compare the performance of various estimation…

  • Research update: Towards a Law of Iterated Expectations for Heuristic Estimators

    Last week, ARC released a paper called Towards a Law of Iterated Expectations for Heuristic Estimators, which follows up on previous work on formalizing the presumption of independence. Most of the work described here was done in 2023. A brief table of contents for this post: What is a heuristic

  • Estimating Tail Risk in Neural Networks

    Machine learning systems are typically trained to maximize average-case performance. However, this method of training can fail to meaningfully control the probability of tail events that might cause significant harm.

  • Backdoors as an analogy for deceptive alignment

    ARC has released a paper on Backdoor defense, learnability and obfuscation in which we study a formal notion of backdoors in ML models. Part of our motivation for this is an analogy between backdoors and deceptive alignment, the possibility that an AI system would intentionally behave well in…

  • Formal verification, heuristic explanations and surprise accounting

    ARC's current research focus can be thought of as trying to combine mechanistic interpretability and formal verification. If we had a deep understanding of what was going on inside a neural network, we would hope to be able to use that understanding to verify that the network was

  • Matrix completion prize results

    Earlier this year ARC posted a prize for two matrix completion problems. We received a number of submissions we considered useful, but not any complete solutions. We are closing the contest and awarding the following partial prizes:$500 to Elad Hazan for solving a related problem and pointing us
