Equilibrium Reasoners: Learning Attractors Enables Scalable Reasoning

This paper introduces Equilibrium Reasoners (EqR), a novel framework that conceptualizes iterative AI reasoning as a dynamical system converging toward stable latent attractors. By treating the reasoning process as a series of repeated updates to an internal state, the researchers demonstrate that models can scale performance at test-time by simply increasing the number of iterations (depth) or using multiple random starts (breadth). This approach allows a model trained on only 16 iterations to generalize to over 1,000 steps during inference, effectively unrolling the equivalent of 40,000 neural layers. This "attractor perspective" ensures that as the system reaches a mathematical equilibrium, it simultaneously settles on a correct task solution, resulting in near-perfect accuracy on complex benchmarks like Sudoku-Extreme and Maze-Unique. Ultimately, the research proves that aligning a model's internal landscape with task-specific goals enables adaptive computation, where harder problems receive more processing power to reach a valid conclusion.

Position: The Pre/Post-Training Boundary Should Govern IP in Industry–Academia ML Collaborations

This paper proposes a new contractual framework called PBOS to resolve persistent intellectual property conflicts in industry-academia machine learning collaborations. By involving scientists in legal negotiations, the authors suggest a clear division based on the pre/post-training boundary of a model. Under this model, pre-training artifacts such as code and architectures are treated as open science, while post-training weights derived from proprietary data remain protected corporate assets. This approach ensures researchers can fulfill academic publication requirements without compromising a company's competitive advantage. Ultimately, the framework aims to reduce the high transaction costs and legal delays that currently prevent many valuable large-scale research partnerships.

MEMO: Memory as a Model

MEMO (Memory as a Model), a modular framework designed to integrate new, domain-specific knowledge into Large Language Models (LLMs) without the need for expensive retraining. By encoding information into a dedicated, smaller MEMORY model while keeping the primary EXECUTIVE model frozen, the system avoids catastrophic forgetting and remains compatible with proprietary, closed-source models. The process involves a five-step data synthesis pipeline that converts raw documents into a structured question-answer dataset of "reflections" that capture complex, cross-document relationships. At inference, the EXECUTIVE model retrieves information through a structured multi-turn protocol, decomposing difficult queries into targeted sub-questions. Empirical results across multiple benchmarks demonstrate that MEMO is more robust to retrieval noise than standard methods and achieves superior performance by leveraging internalized parametric knowledge. Furthermore, the framework supports continual knowledge integration through model merging, allowing new data to be added efficiently while maintaining a retrieval cost that is independent of the overall corpus size.

Agent Bazaar: Enabling Economic Alignment in Multi-Agent Marketplaces

This research introduces Agent Bazaar, a multi-agent simulation framework designed to evaluate and improve the Economic Alignment of Large Language Models (LLMs). The authors identify two critical failure modes: The Crash, where agents engage in destructive price-cutting that leads to market collapse, and The Lemon Market, where deceptive agents use multiple identities to flood marketplaces with fraudulent listings. Experiments reveal that standard frontier models often fail to self-regulate, regardless of their size or general reasoning capabilities. To address these risks, the study proposes specialized agent harnesses and uses targeted reinforcement learning to train a 9B model that achieves superior market stability and integrity. Performance is measured using the new Economic Alignment Score (EAS), which aggregates stability, integrity, welfare, and profitability into a single metric. Ultimately, the work demonstrates that economic safety is a distinct property that can be successfully cultivated through specialized training.

General Preference Reinforcement Learning

This paper introduces General Preference Reinforcement Learning (GPRL), a novel post-training framework designed to align large language models with complex human values. Traditional methods often rely on a scalar reward model, which frequently leads to "reward hacking" as the model exploits a single quality dimension at the expense of others. To resolve this, the authors utilize a General Preference Model (GPM) that embeds responses into multiple subspaces, representing quality as a multi-dimensional, structured signal. GPRL estimates advantages for each dimension independently, ensuring that no single axis can dominate the learning process through normalized scaling. The system also features a closed-loop drift monitor that detects and corrects single-axis exploitation in real-time by reweighting dimensions and tightening trust regions. Experimental results show that GPRL significantly outperforms existing methods like DPO and GRPO on benchmarks such as AlpacaEval 2.0 and Arena-Hard by resisting stylistic drift. Ultimately, the research suggests that the future of open-ended alignment lies in the mathematical shape of rewards rather than just their strength.
