The Genesis of o1-mini

The development of o1-mini stems from a recognition of the limitations inherent in large language models (LLMs) like GPT-3 and GPT-4. While these models have demonstrated impressive capabilities across a wide range of tasks, their size and broad training scope often result in high computational costs and slower processing times. OpenAI’s approach with o1-mini was to create a more focused, streamlined model that could match or exceed the performance of larger models in specific domains, particularly in STEM reasoning.

A New Paradigm in Model Training

The creation of o1-mini represents a shift in the approach to model training. Rather than relying solely on vast amounts of diverse data, OpenAI has employed a more targeted strategy:

Specialized Pre-training: o1-mini’s initial training focused heavily on STEM-related content, creating a strong foundation for mathematical and scientific reasoning.
Reinforcement Learning Pipeline: Following the initial pre-training, o1-mini underwent the same high-compute reinforcement learning process as its larger counterpart, OpenAI o1. This step was crucial in refining the model’s ability to apply its knowledge effectively.
Efficiency Optimization: Throughout the development process, a strong emphasis was placed on optimizing the model for speed and cost-efficiency, ensuring that o1-mini could deliver high performance without the resource requirements of larger models.

Key Features and Availability

OpenAI has made o1-mini accessible to a wide range of users, reflecting their commitment to democratizing advanced AI technologies:

Broader STEM Applications

While mathematics and coding are clear strengths, o1-mini’s capabilities span a wider range of STEM fields:

GPQA (Science): On this benchmark focused on scientific reasoning, o1-mini outperformed GPT-4o, demonstrating its strong grasp of scientific concepts and methodologies.
MATH-500: This comprehensive mathematics test further showcased o1-mini’s capabilities, with the model again surpassing GPT-4o’s performance.

It’s worth noting that while o1-mini excels in these specialized areas, it does lag behind o1-preview on some broader knowledge tests like GPQA. This is a direct result of its specialized training, which prioritized depth in STEM fields over breadth of general knowledge.

Specialized Pre-training

Unlike more general models that are trained on vast, diverse datasets, o1-mini’s pre-training phase was heavily focused on STEM content. This includes:

Advanced mathematics textbooks and research papers
Computer science literature and coding repositories
Scientific journals across various disciplines
Engineering and technical documentation

This specialized dataset allowed the model to develop a deep understanding of STEM concepts, terminology, and problem-solving approaches.

Reinforcement Learning Optimization

Following the pre-training phase, o1-mini underwent an extensive reinforcement learning (RL) process. This phase was crucial in teaching the model how to apply its knowledge effectively:

Problem-Solving Simulations: The model was presented with countless STEM problems and rewarded for correct solutions.
Efficiency Training: The RL process also focused on optimizing the model’s response time and resource usage, ensuring that it could provide quick, accurate answers without excessive computational overhead.
Error Correction: Through iterative feedback, the model learned to identify and correct common mistakes in STEM reasoning, improving its overall accuracy.

Model Speed

As a concrete example, we compared responses from GPT-4o, o1-mini, and o1-preview on a word reasoning question. While GPT-4o did not answer correctly, both o1-mini and o1-preview did, and o1-mini reached the answer around 3–5x faster.

Safety

o1-mini is trained using the same alignment and safety techniques as o1-preview. The model has 59% higher jailbreak robustness on an internal version of the StrongREJECT dataset compared to GPT-4o. Before deployment, we carefully assessed the safety risks of o1-mini using the same approach to preparedness, external red-teaming, and safety evaluations as o1-preview. We are publishing the detailed results from these evaluations in the accompanying.
