📝 摘要(中文)

本研究提出了一种通用框架,用于训练大型语言模型(LLMs)以实现“连接点”(CoD)能力,这是长生命周期智能体所需的元能力。该框架允许LLM在环境中部署后,解决一系列任务,同时不断探索环境、学习自身经验并迭代更新其环境上下文,从而在未来任务中实现更好的表现。CoD框架的主要组成部分包括:端到端强化学习(RL)算法设计和基础设施,长回合序列交替解决任务和更新上下文的过程,以及激励和引导LLMs在训练期间获得目标元能力的任务和环境。通过概念验证实现,结果验证了CoD设置下端到端RL训练的有效性,并展示了在不同领域和CoD到Ralph-loop设置中的跨域泛化潜力。

🔬 方法详解

问题定义:本论文旨在解决长生命周期智能体在动态环境中任务解决和上下文更新的能力不足,现有方法难以实现有效的跨域泛化。

核心思路:提出CoD框架,通过设计长回合序列的端到端强化学习算法,使LLMs能够在任务解决过程中不断更新环境上下文,从而提升其适应性和表现。

技术框架:CoD框架包括两个主要模块:一是长回合序列的RL算法,二是用于激励和评估LLMs元能力的任务和环境设计。算法通过交替的解决任务和更新上下文的过程,形成闭环学习机制。

关键创新:最重要的创新在于引入了长回合序列的RL训练方式,使得LLMs能够在任务执行中动态调整其上下文,这与传统的逐任务RL方法有本质区别。

关键设计:在算法设计中,采用了GRPO风格的RL算法,细化了信用分配机制,确保在长回合中能够有效评估和优化LLMs的表现。

📄 摘要(原文)

This work presents a general framework for training large language models (LLMs) to "Connect the Dots" (CoD), a meta-capability required by long-lifecycle agents: as an LLM-based AI agent gets deployed in an environment, it solves a long sequence of tasks while continuously exploring the environment, learning from its own experiences, and iteratively self-updating its context about the environment, thereby achieving progressively better performance on future tasks conditioned on the updated context. Major components of the CoD framework include: (1) algorithm design and infrastructure for end-to-end reinforcement learning (RL) with long rollout sequences interleaving solve-task and update-context episodes; (2) tasks and environments for incentivizing and eliciting the targeted meta-capability in LLMs during training, as well as for faithfully measuring progress during evaluation. We present proof-of-concept implementations of the CoD framework, including a GRPO-style RL algorithm with fine-grained credit assignment, as well as tasks and environments tailored to the targeted meta-capability (rather than domain-specific LLM capabilities or standard task-by-task RL). Empirical results validate the efficacy of end-to-end RL training in the CoD setting, and demonstrate the potential for out-of-distribution generalization -- within the training domains, across different domains, and from CoD to Ralph-loop settings -- of the elicited meta-capability. Our investigation of CoD connects several lines of prior works, and opens up new opportunities for advancing LLMs and AI agents. To facilitate further research and applications, we release our implementations at \url{https://github.com/agentscope-ai/Trinity-RFT/tree/research/cod/examples/research_cod}.
