    When can in-context learning generalize out of task distribution?

    The research empirically investigates the role of pretraining distribution and a new concept of task diversity in the emergence of ICL, particularly using models trained on linear functions. Findings indicate that increasing task diversity causes transformers to shift from a specialized solution to one that can generalize across the entire task space, a transition also observed in nonlinear regression problems. The authors constructed a phase diagram to characterize how task diversity and the number of pretraining tasks interact, while also examining the influence of factors like model depth and problem dimensionality.

    The Art of Scaling Reinforcement Learning Compute for LLMs

    This paper studies scaling reinforcement learning (RL) compute for large language models (LLMs), introducing a principled framework to predict performance. The authors develop ScaleRL, a best-practice recipe derived from ablating various algorithmic choices, and demonstrate its predictable scaling trajectory using a sigmoidal function to fit compute-performance curves. Accompanying figures illustrate validation performance over increasing GPU hours (log scale) for different RL configurations, showing that ScaleRL achieves higher asymptotic performance and efficiency than prevalent methods while maintaining stability across various scaling axes, including model size and batch size. The work establishes that predictable scaling laws, similar to those in LLM pre-training, can be applied to the RL fine-tuning stage.

    A small number of samples can poison LLMs of any size

    This white paper by Anthropic, UK AI Security Institute, and The Alan Turing Institute demonstrates that a small, fixed number of malicious documents—as few as 250—can successfully create a "backdoor" vulnerability in LLMs, regardless of the model's size or the total volume of clean training data. This finding challenges the previous assumption that attackers need to control a percentage of the training data, suggesting that these poisoning attacks are more practical and accessible than previously believed. The study specifically tested a denial-of-service attack that causes the model to output gibberish upon encountering a specific trigger phrase like , and the authors share these results to encourage further research into defenses against such vulnerabilities.

    Dual Goal Representations

    This paper discusses dual goal representations for goal-conditioned reinforcement learning (GCRL), a novel method for encoding a state based on its temporal distance relation to all other states within an environment. The authors theoretically establish that this representation is sufficient for recovering an optimal goal-reaching policy and is invariant to extraneous noise within the state observations. Building on this theory, they propose a practical implementation using an inner product parameterization and offline value learning, demonstrating that this approach consistently improves goal-reaching performance across a suite of robotic navigation and manipulation tasks, outperforming existing representation learning methods. The overall aim is to enhance the efficiency and generalization capability of GCRL agents by providing a robust and structured goal representation.

    Welcome to the Era of Experience

    This "bitter lesson"-style position paper by David Silver and Richard S. Sutton introduces a shift in artificial intelligence from the "Era of Human Data" to the "Era of Experience." The authors argue that AI progress is slowing because the available pool of human-generated data is being exhausted, necessitating a new approach where agents learn predominantly from their own self-generated experience and interaction with the environment. This transition is characterized by agents that inhabit streams of experience rather than short interactions, utilize richly grounded actions and observations, optimize for grounded rewards from the environment, and engage in non-human planning and reasoning to achieve truly superhuman capabilities. The paper positions this new era as a critical next step that will reconcile the task-generality achieved by large language models with the self-discovery of knowledge exemplified by earlier reinforcement learning systems.

    Value Flows: Flow-Based Distributional Reinforcement Learning

    This paper introduces "Value Flows," a novel reinforcement learning algorithm that uses flow-based models to estimate the full future return distribution, instead of flattening it to a single scalar value like traditional methods. This approach is designed to provide richer learning signals and better estimations of aleatoric uncertainty (return variance), which is then used to prioritize learning on uncertain transitions. The abstract and text detail how a new flow-matching objective is formulated to satisfy the distributional Bellman equation, while accompanying images illustrate this concept with a violin plot of return distributions and screenshots of a robotic manipulation task used for evaluation. Experiments demonstrate that Value Flows significantly outperforms prior offline and online-to-online RL methods across various tasks by achieving a 1.3× improvement in success rates and a lower distributional discrepancy.

    Self-Adapting Language Models

    This paper introduces Self-Adapting Large Language Models (SEAL), a novel framework that enables LLMs to autonomously improve by generating their own training data and finetuning instructions, termed "self-edits." This adaptation process is driven by a reinforcement learning (RL) loop that rewards the model for generating self-edits that subsequently improve its performance on downstream tasks, contrasting with static models that learn from data "as-is." The authors demonstrate SEAL's effectiveness in two key domains: knowledge incorporation, where it generates synthetic data to efficiently integrate new facts, and few-shot learning, where it autonomously configures optimal data augmentations and training hyperparameters. Although promising, the work notes limitations regarding computational overhead and susceptibility to catastrophic forgetting during continuous adaptation.

    The Markovian Thinker

    Reinforcement learning (RL) methods for training Large Language Models (LLMs) to produce long chains of thought (LongCoT) are constrained by the standard thinking environment, where the state is unbounded, leading to quadratic computational costs as reasoning length increases. This paper propose Markovian Thinking, a paradigm where the reasoning policy conditions only on a constant-size state, effectively decoupling thinking length from context size and yielding linear compute and constant memory benefits. This concept is instantiated with Delethink, an RL environment that organizes reasoning into fixed-size chunks. At the chunk boundaries, the context resets, and the policy must learn to write a concise textual carryover sufficient for seamless continuation of the reasoning process in the next chunk. Models trained with Delethink, such as R1-Distill 1.5B, match or exceed the performance of LongCoT-RL while significantly reducing computational overhead, demonstrating superior test-time scaling capability far beyond their training budget. They emphasize that redesigning the thinking environment is a powerful lever for achieving efficient and scalable reasoning in LLMs.
