What is Satori?
Satori is a large-scale 7B-parameter language model developed by researchers at MIT, Harvard University, and other institutions, focusing on improving reasoning capabilities. Based on Qwen-2.5-Math-7B, Satori achieves state-of-the-art reasoning performance through small-scale format fine-tuning and large-scale reinforcement learning. Employing the Action Chain of Thought (COAT) mechanism, it optimizes model performance through reinforcement learning, possessing powerful autoregressive search and self-correction capabilities. Satori excels in mathematical reasoning and cross-domain tasks, demonstrating excellent generalization ability. Satori's code, data, and model are all open-source.
Satori's main functions
- Autoregressive search capabilitySatori can perform autoregressive search by reflecting on itself and exploring new strategies, enabling it to complete complex reasoning tasks without external guidance.
- Mathematical reasoningSatori achieved top marks in the mathematical reasoning benchmark test, demonstrating exceptional reasoning ability.
- Cross-domain tasksIn addition to mathematics, Satori also excels in cross-domain tasks such as logical reasoning, code reasoning, common sense reasoning, and table reasoning, demonstrating strong generalization ability.
- Self-reflection and error correction abilitySatori's ability to self-reflect and self-correct during reasoning improves the accuracy of inference, enabling the model to perform exceptionally well in complex reasoning tasks.
- Reinforcement learning optimizationIt employs an Action-Mind Chain (COAT) mechanism and a two-stage training framework, including small-scale format tuning and large-scale self-optimization, and relies primarily on reinforcement learning (RL) to achieve advanced inference performance.
Satori's technical principles
- Action-Mind Chain (COAT) ReasoningSatori introduces the Action-Cognitive Chain (COAT) mechanism, guiding the model's reasoning through special meta-action markers (such as <|continue|>, <|reflect|>, and <|explore|>). These markers are used for:
- Continue reasoningEncourage the model to generate the next intermediate step.
- Reflection: Verify whether the previous reasoning steps were correct.
- Explore alternativesIdentify flaws in reasoning and explore new solutions.
- Two-stage training frameworkSatori employs an innovative two-stage training method:
- Small-scale format optimization phaseFine-tuning was performed on a small dataset with a limited number of inference trajectory examples to familiarize the model with the COAT inference format.
- Large-scale self-optimization stageThe model performance is optimized through reinforcement learning (RL), and the autoregressive search capability of the model is enhanced by using restart and exploration (RAE) techniques.
