LightThinker: Enhancing LLM Efficiency Through Dynamic Compression of Intermediate Thoughts

Enhancing Reasoning with AI Techniques

Methods such as Chain-of-Thought (CoT) prompting improve reasoning by breaking down complex problems into manageable steps. Recent developments, like o1-like thinking modes, bring capabilities such as trial-and-error and iteration, enhancing model performance. However, these advancements require significant computational resources, leading to increased memory demands due to the limitations of the Transformer architecture.

Accelerating LLM Inference

Current strategies to speed up Large Language Model (LLM) inference can be categorized into three areas:

  • Quantizing Model: Reduces model size and memory requirements.
  • Generating Fewer Tokens: Limits the number of tokens produced to enhance efficiency.
  • Reducing KV Cache: Implements pruning and merging strategies to optimize memory usage.

Innovative Solutions with LightThinker

Researchers from Zhejiang University and Ant Group introduced LightThinker, a method that dynamically compresses intermediate reasoning steps, inspired by human cognition. This approach reduces the number of tokens required during reasoning, ultimately lowering memory usage and inference time while maintaining accuracy.

Evaluation of LightThinker

The effectiveness of LightThinker was assessed using various models and datasets. The evaluation included:

  • Full parameter instruction tuning with the Bespoke-Stratos-17k dataset.
  • Comparison of different acceleration methods and evaluation across four distinct datasets.

Key findings showed that LightThinker matches or exceeds the performance of existing methods while significantly reducing inference time.
