How to Train LLMs to Think (o1 & DeepSeek-R1)
Briefly

OpenAI's o1 model, unveiled in September 2024, marks a significant advancement in large language model training by introducing thinking tokens, which facilitate improved reasoning capabilities. While the original details remain confidential, DeepSeek has replicated the model's innovative features, particularly the concept of using tokens during problem-solving processes to optimize performance. A notable finding is that increased test-time compute—specifically the generation of more tokens—exponentially enhances model responses. The thinking tokens serve two crucial functions: they help clarify the model's reasoning and improve usability in practical applications by generating a readable thought process.
OpenAI's o1 model introduced thinking tokens to enhance reasoning capabilities in large language models by providing a structured method for problem-solving and enhancing model performance.
DeepSeek has successfully replicated the reasoning behavior of OpenAI's o1 model, providing full technical details on their innovative approach to large language model training.
The major insight from o1 is that performance improves with increased test-time compute, indicating that generating more tokens during response enhances model accuracy.
Thinking tokens are essential for delineating a model's reasoning process, allowing for clear interpretation and effective UI integration, thus advancing the usability of large language models.
