Abstract

Large reasoning models (LRMs) already possess a latent capacity for long chain-of-thought reasoning. Prior work has shown that outcome-based reinforcement learning (RL) can incidentally elicit advanced reasoning behaviors such as self-correction, backtracking, and verification phenomena often referred to as the model's "aha moment". However, the timing and consistency of these emergent behaviors remain unpredictable and uncontrollable, limiting the scalability and reliability of LRMs' reasoning capabilities. To address these limitations, we move beyond reliance on prompts and coincidental "aha moments". Instead, we explicitly align models with three meta-abilities: deduction, induction, and abduction, using automatically generated, self-verifiable tasks. Our three stage-pipeline individual alignment, parameter-space merging, and domain-specific reinforcement learning, boosting performance by over 10\% relative to instruction-tuned baselines. Furthermore, domain-specific RL from the aligned checkpoint yields an additional 2\% average gain in the performance ceiling across math, coding, and science benchmarks, demonstrating that explicit meta-ability alignment offers a scalable and dependable foundation for reasoning.

大型推理模型(LRMs)已经具备了潜在的长链推理能力。先前的研究表明,基于结果的强化学习(RL)能够偶然引发诸如自我纠正、回溯和验证等高级推理行为,这些现象通常被称为模型的“顿悟时刻”。然而,这些新兴行为的出现时间和一致性仍然难以预测和控制,这限制了 LRMs 推理能力的可扩展性和可靠性。为了解决这些局限性,我们不再依赖提示和偶然出现的“顿悟时刻”。相反,我们通过自动生成的、可自我验证的任务,明确地将模型与三种元能力——演绎、归纳和溯因——对齐。我们的三阶段流水线——个体对齐、参数空间合并和领域特定的强化学习,相对于指令调优的基线,性能提升了超过 10%。此外,从对齐的检查点获取的特定领域的强化学习在数学、编程和科学基准测试中的性能上限平均提高了 2%,这表明明确的元能力对齐为推理提供了一个可扩展且可靠的基石。代码可在以下网址获取:this https URL

1、Introduction

Large reasoning models, including OpenAI-o1 [11], o3 [17], DeepSeek-R1 [8], Grok 3.5 [27], and Gemini 2.5 Pro [3], have demonstrated remarkable capabilities. These models excel at generating long Chain-of-Thought (CoT) [24] responses when tackling complex tasks and exhibit advanced, reflection-like reasoning behaviors. Recently, DeepSeek-R1 has shown that, starting from pretrained base or instruction-tuned models, pure reinforcement learning (RL) with rule-based rewards can spontaneously lead to the emergence of long CoT reasoning, self-correction, self-reflection, and other advanced behaviors, collectively referred to as the “aha moment”. Other open-source works, such as SimpleRL-Zoo [31], tinyzero [18], and Logic-RL [28], which attempt to reproduce R1’s performance and technical details, have also observed similar aha moments. These behaviors—such as self-correction, self-verification, and backtracking, signal the model’s internal experience of strong reasoning ability.

However, relying solely on emergent behaviors is inherently unreliable and difficult to control. Models may fail to consistently manifest these advanced reasoning schemes, which limits both the predictability and scalability of LLM-based reasoning. To overcome this, we propose to explicitly align LLMs with three domain-general reasoning meta-abilities—deduction, induction, and abduction—drawn from Peirce’s classical inference triad [19].

Deduction infers specific outcomes from general rules and hypotheses (H+R→O), enabling rigorous prediction and verification. Induction abstracts rules from repeated co-occurrences (H+O→R), facilitating pattern discovery and generalization. Abduction infers the most plausible explanation for surprising observations (O+R→H), promoting creative and backward reasoning.

Together, they form a closed inferential loop for hypothesis generation, testing, and revision, mirroring the scientific method and supporting robust and interpretable reasoning.

1. 引言

包括 OpenAI-o1 [11]、o3 [17]、DeepSeek-R1 [8]、Grok 3.5 [27] 和 Gemini 2.5 Pro [3] 在内的大型推理模型展现出了非凡的能力。这些模型在处理复杂任务时能够生成长链的推理过程(CoT)[24],并表现出类似反思的高级推理行为。最近,DeepSeek-R1 表明,从预训练的基础模型或指令微调模型出发,仅通过基于规则的奖励进行纯强化学习(RL),就能自发地产生长链 CoT 推理、自我修正、自我反思等高级行为,这些行为统称为“顿悟时刻”。其他开源项目,如 SimpleRL-Zoo [31]、tinyzero [18] 和 Logic-RL [28],在尝试重现 R1 的性能和技术细节时,也观察到了类似的顿悟时刻。这些行为,如自我修正、自我验证和回溯,表明模型内部具备强大的推理能力。

然而,仅仅依赖于自发产生的行为本质上是不可靠且难以控制的。模型可能无法始终如一地展现出这些高级推理模式,这限制了基于 LLM 的推理的可预测性和可扩展性。为了解决这个问题,我们提议明确地将 LLM 与三种通用推理元能力——演绎、归纳和溯因——对齐,这些元能力源自皮尔士的经典推理三元组[19]。

演绎是从一般规则和假设推断出具体结果(H+R→O),这使得严格的预测和验证成为可能。归纳是从反复出现的共现中抽象出规则(H+O→R),有助于模式发现和概括。溯因是从令人惊讶的观察中推断出最合理的解释(O+R→H),促进创造性和逆向推理。

它们共同构成了一个用于假设生成、测试和修订的封闭推理循环,这与科学方法相呼应,并支持稳健且可解释的推理。

To operationalize these meta-abilities, we construct a task suite with programmatically generated instances and automatic verifiability. Each task targets one core reasoning mode: Deduction: Propositional satisfiability tasks use rule sets R and candidate hypotheses H to test if all premises entail the observation O. Induction: Masked-sequence completion requires models to infer latent rules R from partial inputs H,O. Abduction: Inverse rule-graph search backchains from observed consequences O through a rule graph R to infer the minimal explanatory H. These tasks are constructed from synthetic distributions that lie out-of-distribution relative to common pretraining corpora, ensuring that performance improvements reflect genuine meta-ability acquisition rather than memorization or shortcut exploitation.

We observe that models aligned to individual meta-abilities make complementary errors. Aggregating their predictions raises overall accuracy by more than 10% relative to a vanilla instruction-tuned baseline. To incorporate the three competencies into a single network, we compared two approaches: training on a mixed task corpus and parameter-space model merging. Parameter-space merging improves average accuracy across math, coding, and science by  2% on a 7B model and  4% on a 32B model over the instruction-tuned baseline, demonstrating the strong generalization of merged meta-abilities.

为了将这些元能力付诸实践,我们构建了一个任务套件,其中包含程序生成的实例和自动可验证性。每个任务都针对一种核心推理模式:演绎:命题可满足性任务使用规则集 R 和候选假设 H 来测试所有前提是否蕴含观察结果 O。归纳:掩码序列补全要求模型从部分输入 H、O 中推断出潜在规则 R。溯因:逆向规则图搜索从观察到的后果 O 通过规则图 R 进行反向链推断出最小的解释 H。这些任务由相对于常见预训练语料库处于分布外的合成分布构建而成,确保性能提升反映的是真正的元能力获取,而非记忆或捷径利用。

我们观察到针对单个元能力进行对齐的模型会犯互补的错误。将它们的预测进行聚合,整体准确率比普通的指令调优基线提高了 10% 以上。为了将这三种能力整合到一个网络中,我们比较了两种方法:在混合任务语料库上训练和参数空间模型合并。参数空间合并使 70 亿参数模型在数学、编程和科学领域的平均准确率提高了 2%,使 320 亿参数模型提高了 4%,这表明合并后的元能力具有很强的泛化能力。

Furthermore, to evaluate whether meta-ability alignment offers a stronger foundation for subsequent learning, we resumed domain-specific RL training from a checkpoint that have already been aligned and compared it with the same procedure applied to an instruction-tuned model. Starting from the meta-ability checkpoint raises the attainable performance ceiling: after identical continual domain-specific RL training, the model achieves an average gain of about 2% over its instruction-only counterpart. Our key contributions are as follows:

Task suite for meta-abilities. We introduce a novel RL task suite aligned with three classical meta-abilities—deduction, induction, and abduction—each constructed to train and validate domain-general reasoning skills in large models.

Recipe for Reasoning Mastery. We propose a three-stage recipe (1) independently align models to each meta-ability; (2) merge them via parameter-space integration; and (3) fine-tune with domain-specific RL. This leads to improved generalization and downstream task accuracy.

Upper-bound boost and scalability. We empirically demonstrate that meta-ability alignment raises the performance ceiling: our 7B and 32B models show consistent gains over instruction-tuned baselines, across math, coding, and science benchmarks.

此外,为了评估元能力对齐是否为后续学习提供了更坚实的基础,我们从已经对齐的检查点恢复特定领域的强化学习训练,并将其与应用于指令调优模型的相同过程进行比较。从元能力检查点开始提高了可达到的性能上限:在相同的持续特定领域强化学习训练之后,该模型比仅指令调优的模型平均提高了约 2%。我们的主要贡献如下:

元能力任务套件。我们引入了一个新颖的强化学习任务套件,与三种经典元能力——演绎、归纳和溯因——相一致,每个任务套件都旨在训练和验证大型模型中的领域通用推理技能。

推理精通的配方。我们提出了一种三阶段配方:(1)将模型分别对齐到每个元能力;(2)通过参数空间整合将它们合并;并且(3)使用特定领域的强化学习进行微调。这带来了更好的泛化能力和下游任务的准确性。

上限提升和可扩展性。我们通过实证表明,元能力对齐提高了性能上限:我们的 70 亿和 320 亿参数模型在数学、编程和科学基准测试中均持续优于指令微调的基线模型。

Conclusion

This work demonstrates that large reasoning models need not rely on unpredictable 'aha moments’ to acquire advanced problem-solving skills. By explicitly aligning deduction, induction, and abduction through automatically generated, self-verifiable tasks, we create specialist agents whose complementary strengths can be merged—without extra compute—into a single checkpoint that outperforms an instruction-tuned baseline by more than 10% on purpose-built diagnostics and up to 2% on seven diverse math, code, and science benchmarks. When this meta-ability-aligned model is used as the starting point for domain-specific reinforcement learning, it lifts the attainable performance ceiling by a further 4% and widens the gap as model capacity scales from 7B to 32B parameters. These results confirm that systematic, modular training of fundamental reasoning modes provides a controllable and scalable foundation for downstream capability composition. Future work will explore richer fusion strategies, extend the task suite to multimodal settings, and investigate how explicit meta-ability control can improve interpretability and safety in large-scale reasoning systems.

结论

这项工作表明,大型推理模型无需依赖难以预测的“顿悟时刻”来获取高级问题解决技能。通过自动生成的、可自我验证的任务来明确对演绎、归纳和溯因进行对齐,我们创建了专业代理,它们的互补优势可以在无需额外计算的情况下合并为一个检查点,在专门设计的诊断测试中比指令调优的基线高出 10% 以上,在七个不同的数学、代码和科学基准测试中最多高出 2%。当这种元能力对齐模型用作特定领域强化学习的起点时,它将可实现的性能上限再提高 4%,并且随着模型容量从 70 亿参数扩展到 320 亿参数,差距进一步扩大。这些结果证实,对基本推理模式进行系统化、模块化的训练为下游能力组合提供了一个可控且可扩展的基础。未来的工作将探索更丰富的融合策略,将任务套件扩展到多模态设置,并研究如何通过显式的元能力控制来提高大规模推理系统的可解释性和安全性。
