OpenAI has introduced its latest reasoning model, o3-mini, representing a significant leap in the company’s mission to elevate artificial intelligence capabilities. This strategic launch aims to boost the company’s position in the market, particularly in light of the R1 model from Chinese startup DeepSeek. China’s innovation sent shockwaves through the AI landscape by delivering exceptional performance at significantly lower computational costs. This disruption prompted OpenAI to respond quickly with the launch of o3-mini, contributing to a trillion-dollar tech selloff and reshaping the industry. OpenAI’s newest model is part of OpenAI’s o family of reasoning models and is designed to provide users with more reliable and efficient responses, particularly in technical domains such as programming, math, and science.
Key features of o3-mini
Enhanced reasoning capabilities
Unlike traditional large language models, o3-mini employs a unique approach to reasoning. It fact-checks its responses before delivering them, which helps to minimize errors and improve the accuracy of its outputs. While this process may take slightly longer, the trade-off is a more dependable performance, especially in complex subjects like physics.
Performance metrics
OpenAI claims that o3-mini is comparable to its predecessor models, o1 and o1-mini, in terms of capabilities. However, it operates faster and at a lower cost. External testers have reported that o3-mini’s answers were preferred over those from o1-mini more than half the time. Additionally, it made 39 percent fewer major mistakes on challenging real-world questions during A/B testing.
Accessibility
Starting from its launch, o3-mini is available to all users via ChatGPT. However, users who subscribe to OpenAI’s ChatGPT Plus and Team plans will benefit from a higher query limit of 150 per day, while ChatGPT Pro subscribers will enjoy unlimited access. The model will also be integrated into ChatGPT Enterprise and ChatGPT Edu within a week of its release.
Cost efficiency
The pricing structure for o3-mini is competitive, set at $0.55 per million cached input tokens and $4.40 per million output tokens. This pricing is approximately 63 percent cheaper than o1-mini, making it an attractive option for developers and businesses looking to leverage advanced AI capabilities without incurring excessive costs.

Comparison with competitors
While o3-mini is a powerful tool, it does not surpass all competitors in every benchmark. For instance, it outperformed DeepSeek’s R1 reasoning model on certain tests, such as AIME 2024, but lagged behind on others, particularly in PhD-level physics, biology, and chemistry questions when set to low reasoning effort. OpenAI acknowledges that while o3-mini is not its most powerful model, it provides a specialized alternative for technical domains that require precision and speed.
Safety and reliability
OpenAI has emphasized that o3-mini is designed with safety in mind. The model has undergone extensive red-teaming efforts and employs a methodology known as “deliberative alignment,” which ensures that it adheres to OpenAI’s safety policies while generating responses. According to the company, o3-mini significantly surpasses previous models, including GPT-4o, in challenging safety evaluations.
The launch of o3-mini represents a crucial step forward in OpenAI’s mission to broaden access to advanced AI technologies. By focusing on reasoning capabilities, cost efficiency, and safety, o3-mini aims to provide users with a reliable tool for tackling complex problems in various fields. As the demand for sophisticated AI solutions continues to grow, OpenAI’s latest offering is poised to play a significant role in shaping the future of artificial intelligence.
