rSIM: Incentivizing Reasoning Capabilities of LLMs via Reinforced Strategy Injection
This paper introduces rSIM, a novel reinforced strategy injection mechanism that enables any Large Language Model (LLM) to evolve into a Reasoning Language Model (RLM). By employing a small planner to adaptively inject human-designed reasoning strategies into the LLM's chain-of-thought (CoT), rSIM significantly enhances problem-solving accuracy. The planner, trained jointly with the LLM using multi-agent reinforcement learning, is pluggable, reusable, and supports continual learning across diverse tasks, offering a generalizable solution for improving LLM reasoning without extensive re-training.
Executive Impact
rSIM presents a transformative approach to enhancing LLM capabilities, offering significant improvements in reasoning accuracy and generalization across various tasks. Its modular design allows for rapid deployment and continuous improvement, leading to substantial gains in operational efficiency and problem-solving robustness for enterprise AI.

rSIM introduces a two-agent Multi-Agent Reinforcement Learning (MARL) framework where a small 'planner' (leader) guides a larger LLM 'reasoner' (follower). The planner, a smaller LLM, adaptively selects and injects one of nine human-designed reasoning strategies (e.g., self-reflection, decomposition) into the reasoner's chain-of-thought (CoT) at each step. This mechanism enables even small LLMs (0.5B) to gain advanced reasoning abilities, which traditional RL-based fine-tuning fails to achieve for smaller models. The training uses a leader-follower algorithm with rule-based rewards, ensuring the planner learns to effectively guide the reasoner towards accurate problem-solving. This decoupling of planning from reasoning is a key innovation, allowing the planner to inject human-crafted knowledge as strategies.
The paper highlights four key contributions: 1) Adaptive injection of reasoning strategies via a planner, enabling any LLM to gain RLM-like abilities. 2) Joint training of planner and LLM using MARL's leader-follower algorithm. 3) Pluggable planners that can be integrated with other LLMs without additional training. 4) Continual learning support for planners across various tasks, enhancing their generalization. These contributions signify a shift towards modular and transferable AI reasoning components, addressing limitations of direct RL fine-tuning on smaller LLMs.
Experiments across seven datasets (mathematics, multi-task reasoning, code generation) confirm rSIM's benefits. Small LLMs (e.g., Qwen2.5-0.5B) jointly trained with a planner achieve accuracy comparable to much larger models (Qwen2.5-14B). A planner trained on mathematics, when used as a plug-in, significantly boosts other LLMs' performance on coding tasks (17% higher accuracy on CodeAlpaca-20k). The planner is shown to generalize across LLMs and tasks, supporting continual learning and demonstrating a strong positive correlation between the number of strategies applied and model accuracy. This indicates that rSIM effectively transforms less capable LLMs into strong reasoners.

Qwen2.5-0.5B Transformed into an RLM
Prior to rSIM, smaller base models like Qwen2.5-0.5B inherently lacked the capacity to perform basic reasoning strategies, and traditional RL-based post-training methods were unable to transform them into capable RLMs. With rSIM, this 0.5B model, when jointly trained with a similarly sized planner, evolved into an RLM achieving accuracy on par with significantly larger models such as Qwen2.5-14B. This remarkable transformation highlights rSIM's ability to directly inject and reinforce advanced reasoning capabilities, demonstrating its potential for democratizing high-performance AI reasoning.
