OpenAI o3 mini vs DeepSeek R1: detailed comparison
Two major innovations are redefining the standards of artificial intelligence. DeepSeek R1 is shaking up industry giants with an open-source model boasting exceptional performance, cutting costs by over 90%. In response, OpenAI is unveiling o3 mini, an optimized AI that is revolutionizing the STEM field with response times 24% faster than its predecessor. Faced with these two distinct approaches, which model will meet your requirements?
A revolution in AI in 2025
Discover how the artificial intelligence landscape was shaken in early 2025 by the arrival of two major models. According to the latest Morningstar data, DeepSeek R1 delivers performance similar to industry giants for a cost reduced by over 90%. Opposite it, OpenAI o3 mini positions itself as a powerful alternative, especially in the STEM domain. But which of these AIs best suits your needs?
OpenAI o3 mini: the optimized STEM expert
Performance and speed
The latest from OpenAI stands out for its targeted approach and remarkable efficiency. Designed specifically to excel in scientific and technical fields, o3 mini introduces several major innovations. Its first strength lies in its exceptional processing speed. With an average response time of 7.7 seconds, it surpasses its predecessor, o1-mini, by 24%. This speed does not come at the cost of quality: the model maintains high-level performance, notably in mathematics and programming.

Cost optimization and control
Economics are also a key factor. OpenAI has optimized usage costs, making o3 mini 63% cheaper than o1-mini. This significant price reduction positions it favorably against competitors, particularly for intensive workloads. The model also offers a unique feature: the control of reasoning effort. With three available levels (low, medium, high), users can precisely balance speed and accuracy according to their needs.
Identified limitations
However, o3 mini does show certain limitations. While advantageous in STEM areas, its specialization can make it less versatile for general tasks. Furthermore, some tests such as GPQA Diamond show more modest performance on doctoral-level scientific questions.
DeepSeek R1: the promising open-source alternative
Innovation and performance
DeepSeek R1 disrupts established norms by offering an open-source model with remarkable performance. This Chinese AI proves that world-class results can be achieved without the colossal resources of American giants.
Strengths and versatility
Its main asset is its versatility. Tests demonstrate performance comparable to models from OpenAI, Anthropic, and Alphabet, particularly in reasoning tasks. The model is especially strong in mathematics, showing impressive scores on benchmarks like AIME 2024 (79.8%) and MATH-500 (97.3%). The open-source nature of DeepSeek R1 is a major advantage. Developers can not only use the model for free but also adapt it to their specific needs. This flexibility paves the way for numerous innovations and customizations.

Challenges and limitations
Nevertheless, some challenges remain. The model can sometimes produce infinite repetitions or incoherent outputs if the temperature is not correctly set. Additionally, the absence of an integrated prompt system requires special attention when formulating queries.
Direct comparison: performance and use cases
Comparative analysis
In terms of pure performance, both models excel in different areas. For STEM tasks, o3 mini delivers remarkable efficiency and faster response times. DeepSeek R1 shines with its versatility and overall performance.
Cost-effectiveness
The cost-effectiveness ratio favors DeepSeek R1 for users looking for a comprehensive and open-source solution. However, o3 mini remains more appealing for businesses seeking a reliable and fast STEM solution with professional support.
Selection guide based on needs
For developers: DeepSeek R1 offers maximum flexibility thanks to its open-source code and customization options. For businesses: OpenAI o3 mini is a safe choice, especially for organizations working in STEM fields. For research: Both models offer distinct advantages for exploration and analysis. For general use: DeepSeek R1 is more versatile, while o3 mini excels in technical domains.
The future of AI: your choice today
Comparative overview
The emergence of these two models marks a turning point in the accessibility of high-performance AI. DeepSeek R1 shows that it is possible to create world-class models at lower cost, while o3 mini demonstrates the value of a well-thought-out specialization.
Final recommendations
When making your choice, consider your specific needs above all. Choose OpenAI o3 mini for STEM applications requiring speed and precision. Opt for DeepSeek R1 if you are looking for a versatile and customizable solution. The near future will undoubtedly bring more exciting innovations, but these two models already offer solid options for the current challenges of AI. Their complementarity, rather than direct opposition, enriches the artificial intelligence ecosystem by providing more choices and possibilities to users.
