    The Era of Agentic Organization: Learning to Organize with Language Models

    This paper introduces **Asynchronous Thinking (AsyncThink)**, a novel paradigm for large language model (LLM) reasoning designed to enable **agentic organization** and collaborative problem-solving. AsyncThink employs an **organizer-worker thinking protocol** where an LLM acts as an organizer that dynamically structures concurrent processes using **Fork and Join actions**, while workers execute sub-queries. The authors compare AsyncThink favorably to traditional sequential and parallel thinking approaches, demonstrating that it achieves **higher accuracy and reduced critical-path latency** across complex tasks like multi-solution countdown and mathematical reasoning. Training is accomplished through a two-stage process involving **cold-start format fine-tuning** followed by **reinforcement learning (RL)**, which optimizes the model for correctness, format compliance, and thinking concurrency. Furthermore, the results show that AsyncThink's capability for organizing thought processes **generalizes well** to previously unseen domains and problem types.

    Understanding neural networks through sparse circuits

    This paper by OpenAI discusses a new approach to **neural network interpretability** through the use of **sparse circuits**. The authors explain that understanding the behavior of complex, hard-to-decipher neural networks is critical for safety and oversight as AI systems become more capable. They distinguish their work on **mechanistic interpretability**, which seeks to fully reverse-engineer computations, from other methods like chain-of-thought interpretability. The core of their research involves training **sparse models**—models with far fewer internal connections—to create simpler, **disentangled circuits** that are easier to analyze and understand, offering a promising path toward making even larger AI systems transparent.

    Supervised Reinforcement Learning: From Expert Trajectories to Step-wise Reasoning

    The academic paper introduces Supervised Reinforcement Learning (SRL), a novel training framework for Large Language Models (LLMs) developed by researchers from Google Cloud AI Research and UCLA to address the difficulty of multi-step reasoning. SRL reformulates problem-solving as a sequence of logical actions, providing dense, step-wise rewards based on the similarity between the model's generated actions and expert trajectories, which contrasts with the sparser, final-outcome rewards used in Reinforcement Learning with Verifiable Rewards (RLVR). The framework trains models to generate an internal reasoning monologue before committing to an action, encouraging flexible and sophisticated reasoning patterns like interleaved planning and verification. Extensive experiments on challenging mathematical reasoning and agentic software engineering benchmarks demonstrate that SRL significantly outperforms baseline methods like Supervised Fine-Tuning (SFT) and RLVR, especially when used to initialize training before subsequent RLVR refinement.

    Multi-Agent Evolve: LLM Self-Improvement Through Co-Evolution

    This research paper introduces Multi-Agent Evolve (MAE), a novel reinforcement learning framework designed to enable large language models (LLMs) to self-improve their general reasoning abilities without relying on human-curated datasets or verifiable external rewards. MAE accomplishes this through a system where a single LLM is instantiated into three interacting roles—a Proposer that creates challenging questions, a Solver that attempts to answer them, and a Judge that evaluates both the questions and answers. This triad operates in a closed-loop co-evolution process, driven by domain-agnostic self-rewarding mechanisms like difficulty-aware and quality rewards, which allows the model to continuously generate better training material and enhance its capabilities across diverse benchmarks like mathematics, coding, and general knowledge. The experiments demonstrate that this multi-agent, self-play approach outperforms traditional Supervised Fine-Tuning (SFT), particularly highlighting its stability and effectiveness in generating a self-improving training signal.

    LeJEPA: Provable and Scalable Self-Supervised Learning Without the Heuristics

    This paper introduces a novel self-supervised learning framework designed to resolve the pervasive issue of representation collapse in existing Joint-Embedding Predictive Architectures (JEPAs). It establishes a theoretical foundation by proving that an isotropic Gaussian distribution is the optimal embedding distribution for minimizing the worst-case risk across various downstream tasks. To enforce this optimal distribution, the paper proposes SIGReg (Sketched Isotropic Gaussian Regularization), a scalable method that uses directional statistical tests, specifically recommending the Epps-Pulley test, to match the empirical feature distribution to the target Gaussian. The core contribution is the resulting LeJEPA loss function, which combines the standard JEPA prediction objective with SIGReg, effectively eliminating the need for complex anti-collapse heuristics like stop-gradients or teacher-student networks, and demonstrating robust, state-of-the-art performance with significantly reduced training complexity.

    PREFDISCO: Evaluating Proactive Personalization through Interactive Preference Discovery

    This paper introduce a new meta-benchmark designed to evaluate large language models' (LLMs) ability to perform **interactive preference discovery** and response personalization through conversation. The framework converts existing benchmarks into interactive tasks by assigning **psychologically-grounded personas** with hidden preferences to be discovered by the AI. Evaluation of numerous frontier models showed that simply attempting personalization often **degraded performance** compared to generic responses (42.6% of cases), indicating systematic failures in current architectures. The research established a strong positive correlation between **question-asking volume** and preference alignment, but noted that models tend not to ask enough questions, and personalization also often imposes a **cognitive cost** that reduces task accuracy, particularly in mathematical reasoning. Ultimately, the source argues that interactive preference discovery is a **distinct capability** requiring dedicated architectural innovations rather than relying on emergent general language understanding.

    Reusing pre-training data at test time is a compute multiplier

    The academic paper investigates the efficiency of Large Language Model (LLM) pre-training by quantifying the amount of knowledge left unextracted from training datasets. The authors demonstrate that employing retrieval-augmented generation (RAG) at test time, which involves reusing the pre-training data, leads to significant accuracy improvements across benchmarks like MMLU, Math-500, and SimpleQA, even after decontamination efforts. The study establishes that retrieval acts as a compute multiplier, with performance gains for MMLU sometimes equivalent to about a 5x increase in pre-training compute alone. Furthermore, the researchers show that combining RAG with additional test-time compute techniques, such as self-consistency and reranking, yields even greater gains, suggesting substantial room for improvement in both dataset quality and current pre-training methodologies. Overall, the findings indicate that LLMs are not fully utilizing the information present in existing datasets and that retrieval offers a powerful, additive way to enhance performance.

    Scaling Agent Learning via Experience Synthesis

    The academic paper proposes **DreamGym**, a novel, unified framework for scaling agent learning using reinforcement learning (RL) by synthesizing diverse experiences instead of relying on costly real-environment rollouts. The core of this system is a **reasoning-based experience model** that abstracts environment dynamics into a textual space, enabling the generation of consistent state transitions and reward signals through explicit reasoning. DreamGym integrates an **experience replay buffer** to enrich synthetic data and a **curriculum task generator** that creates progressively challenging problems based on reward entropy, thereby addressing common RL challenges like sparse rewards and task scarcity. Experimental results across diverse environments, including those not traditionally "RL-ready" like WebArena, demonstrate that DreamGym substantially **improves RL training efficiency** and yields significant performance gains in both purely synthetic settings and sim-to-real transfer scenarios.
