Satori: Reinforcement Learning with Chain-of-Action-Thought Enhances LLM Reasoning via Autoregressive Search
Satori introduces a novel approach to fundamentally enhance a single LLM's reasoning abilities through autoregressive search, self-reflection, and self-exploration. By internalizing search capabilities, Satori bypasses the need for external LLM verifiers common in two-player systems. It employs a two-stage training paradigm: a small-scale format tuning (FT) stage to internalize the Chain-of-Action-Thought (COAT) reasoning format, followed by a large-scale self-improvement stage leveraging reinforcement learning (RL) with Restart and Explore (RAE) techniques. This 7B LLM achieves state-of-the-art performance on mathematical reasoning benchmarks and demonstrates strong generalization to out-of-domain tasks, all with minimal supervision.
Satori delivers a significant breakthrough in LLM reasoning by achieving state-of-the-art performance in complex mathematical tasks and demonstrating robust transferability to diverse out-of-domain problems. Unlike previous methods relying on extensive external supervision or two-player verification systems, Satori, a single 7B LLM, learns autoregressive search internally, showcasing superior efficiency and effectiveness. Its self-correction capabilities are particularly strong, converting a substantial percentage of incorrect solutions to correct ones across various benchmarks, and it exhibits test-time scaling behavior, progressively allocating more computational resources to solve harder problems. This approach, built on open-source models and data, promises more deployable and versatile AI agents.

Satori's Two-Stage Training Framework
Satori employs a novel two-stage training paradigm designed to internalize advanced reasoning capabilities:
- Format Tuning (FT): A small-scale stage (10K samples) that teaches the LLM the Chain-of-Action-Thought (COAT) reasoning format using imitation learning. This stage relies on a multi-agent data synthesis framework to generate high-quality demonstration trajectories incorporating meta-actions like `continue`, `reflect`, and `explore`.
- Self-Improvement: A large-scale stage (300K samples) that uses Reinforcement Learning (specifically PPO) to refine the LLM's reasoning. This stage is critically supported by the "Restart and Explore" (RAE) strategy, which enables the model to restart from intermediate steps (both correct and incorrect) to correct errors and explore new paths. Reward design includes Rule-based, Reflection, and Preference Bonuses.
- Iterative Self-Improvement: Knowledge from optimized policies is distilled back into the base model via SFT, helping the model escape local optima and ensure continuous progress.
Breakthrough AI Capabilities
Satori introduces several core innovations that fundamentally enhance LLM reasoning:
- Chain-of-Action-Thought (COAT): Integrates special meta-action tokens (`<|continue|>`, `<|reflect|>`, `<|explore|>`) into the reasoning process. This allows the LLM to autonomously reflect on, verify, and explore alternative solutions, moving beyond static Chain-of-Thought prompting.
- Restart and Explore (RAE): An RL strategy that empowers the LLM to restart reasoning from diverse intermediate steps of both correct and incorrect past trajectories. This effectively tackles long-horizon problems and sparse rewards by facilitating targeted error correction and broad exploration.
- Unified Autoregressive Search: Satori represents a paradigm shift by being a single LLM capable of internalizing complex search capabilities. This eliminates the need for external verifiers or auxiliary models, simplifying deployment and increasing self-sufficiency.
- Minimal Supervision for Advanced Reasoning: Achieves state-of-the-art performance with only 10K human-annotated samples in the initial format tuning stage, demonstrating remarkable efficiency in leveraging self-improvement through RL.
Empirical Performance & Efficiency
Satori demonstrates superior performance across key benchmarks:
- State-of-the-Art on Math: Satori-Qwen-7B (Round 2) achieved an average pass@1 of 64.4% across challenging mathematical benchmarks (GSM8K, MATH500, OlympiadBench, AMC2023, AIME2024), significantly outperforming baseline instruct models on the same base.
- Enhanced Self-Correction: RL training boosts self-correction capabilities. Satori-Qwen-7B demonstrated a 61.0% positive self-correction rate (F->T) on MATH500, converting incorrect solutions to correct ones.
- Test-Time Scaling Behavior: Satori learns to dynamically allocate more computational resources (longer response length) to tackle harder problems, consistently improving accuracy with increased RL training-time compute.
- COAT vs. CoT Superiority: Ablation studies show that COAT reasoning, with its integrated meta-actions, significantly outperforms classical Chain-of-Thought (CoT) reasoning, validating the benefits of self-reflection and exploration.
Broad Adaptability & Future-Proofing
Satori exhibits remarkable transferability and scalability:
- Out-of-Domain Transferability: Despite being trained exclusively on math datasets, Satori-Qwen-7B shows strong generalization to diverse out-of-domain benchmarks, including logical reasoning, code reasoning, commonsense reasoning, and scientific knowledge, often surpassing instruct models of similar scale.
- Universal Self-Reflection: The self-correction capabilities acquired through RL extend effectively to out-of-domain tasks, indicating that Satori develops general-purpose reasoning skills rather than task-specific ones.
- Iterative Improvement: The iterative self-improvement strategy consistently leads to performance gains across both in-domain and out-of-domain tasks over multiple training rounds.
- Distillation for Efficiency: Satori's robust reasoning capabilities can be distilled into weaker base models (e.g., Llama-8B), significantly enhancing their performance and offering an efficient pathway to empower smaller LLMs for advanced tasks.

Case Study: Dynamic Problem Solving with Self-Correction
Satori demonstrates advanced reasoning through its ability to identify and correct mistakes, even proposing alternative strategies. In a complex AIME2024 mathematical reasoning problem (Figure 7), Satori initially attempts to solve for unknown variables, but recognizes its approach is "overly complicated". It then leverages its reflect meta-action to reassess and proposes an alternative, more efficient solution by focusing on the difference in walking times. This dynamic self-correction leads to the successful identification of the correct answer, showcasing its deep reasoning and problem-solving flexibility.
This capability is crucial for enterprise AI, where complex tasks often involve iterative refinement and error identification, allowing Satori to act as a more autonomous and reliable problem-solver.
