提出可模块化构建推理大模型的蓝图,降低技术门槛。

Reasoning Language Models: A Blueprint

  • 将推理模型拆解为可组合的模块,支持灵活搭建
  • 涵盖搜索、强化学习、监督策略等核心技术组件
  • 适合研究者快速实验,推动推理能力普惠

推理语言模型(RLMs),如OpenAI的o1、o3,DeepSeek-R1和阿里巴巴的QwQ,通过融合强化学习、搜索启发式与大语言模型,显著提升AI问题求解能力。然而其高昂成本、专有性及复杂架构带来可访问性与扩展性挑战。为此,我们基于对所有相关工作的调研分析,提出一个全面的模块化蓝图,整合链式、树形、图结构及嵌套形式的推理机制,涵盖蒙特卡洛树搜索、束搜索等策略,以及策略模型、价值模型、结果/过程监督等概念,并包含测试时计算、检索增强生成、智能体工具等要素。提供数学表达与算法规范以简化实现。通过展示LLaMA-Berry、QwQ、Journey Learning与思维图谱作为特例,验证其统一潜力。进一步推出x1框架,支持快速原型开发。结合文献综述,揭示多阶段训练、熟悉分布训练的重要性。最后讨论云端可扩展部署与与通用大模型生态集成。本工作旨在解构推理模型构建逻辑,推动先进推理能力普及,缩小‘富人工智能’与‘贫人工智能’之间的差距。

原文摘要 · Abstract (English)

Reasoning language models (RLMs), also known as Large Reasoning Models (LRMs), such as OpenAI's o1 and o3, DeepSeek-R1, and Alibaba's QwQ, have redefined AI's problem-solving capabilities by extending LLMs with advanced reasoning mechanisms. Yet, their high costs, proprietary nature, and complex architectures - uniquely combining reinforcement learning (RL), search heuristics, and LLMs - present accessibility and scalability challenges. To address these, we propose a comprehensive blueprint that organizes RLM components into a modular framework, based on a survey and analysis of all RLM works. This blueprint incorporates diverse reasoning structures (chains, trees, graphs, and nested forms), reasoning strategies (e.g., Monte Carlo Tree Search, Beam Search), RL concepts (policy, value models and others), supervision schemes (Outcome-Based and Process-Based Supervision), and other related concepts (e.g., Test-Time Compute, Retrieval-Augmented Generation, agent tools). We also provide detailed mathematical formulations and algorithmic specifications to simplify RLM implementation. By showing how schemes like LLaMA-Berry, QwQ, Journey Learning, and Graph of Thoughts fit as special cases, we demonstrate the blueprint's versatility and unifying potential. To illustrate its utility, we introduce x1, a modular implementation for rapid RLM prototyping and experimentation. Using x1 and a literature review, we provide key insights, such as multi-phase training for policy and value models, and the importance of familiar training distributions. Finally, we discuss scalable RLM cloud deployments and we outline how RLMs can integrate with a broader LLM ecosystem. Our work demystifies RLM construction, democratizes advanced reasoning capabilities, and fosters innovation, aiming to mitigate the gap between "rich AI" and "poor AI" by lowering barriers to RLM design and experimentation.
