OpenAI introduces o1-mini, a cost-effective reasoning model focused on STEM disciplines. The model demonstrates impressive performance in math and coding, very similar to its predecessor, OpenAI o1, on several evaluation benchmarks. OpenAI anticipates that o1-mini will serve as a fast and cost-effective solution for applications that demand reasoning capabilities without extensive global knowledge. The o1-mini release is targeted at API level 5 users and offers an 80% cost reduction compared to OpenAI o1-preview. Let’s take a deeper look at how o1 Mini works.
Overview
- OpenAI's o1-mini is a cost-effective STEM reasoning model that outperforms its peers.
- Specialized training makes o1-mini a STEM expert, excelling in math and coding.
- Human evaluations show o1-mini's strengths in reasoning, favoring it over GPT-4o.
- Security measures ensure responsible use of o1-mini, with improved jailbreak robustness.
- OpenAI's innovation with o1-mini offers a trustworthy and transparent STEM tool.
o1-mini vs other LLMs
LLMs are usually pre-trained on large text datasets, but here’s the catch: while they have this vast knowledge, they can sometimes get a little complicated. You see, all this information makes using them in real-world situations a bit slow and expensive.
What sets o1-mini apart from other LLMs is the fact that it is STEM-trained. This specialized training makes o1-mini an expert in STEM-related tasks. The model is efficient and cost-effective, perfect for STEM applications. Its performance is impressive, especially in math and coding. O1-mini is optimized for speed and accuracy in STEM reasoning. It is a valuable tool for researchers and educators.
o1-mini excels on intelligence and reasoning metrics, outperforming o1-preview and o1, but struggles with non-STEM factual knowledge tasks.

The o1-mini's stellar performance: math, coding, and more
The OpenAI o1-mini model has been put through its paces in several competitions and benchmarks, and its performance is quite impressive. Let’s look at the different components one by one:
Math
In the AIME high school math competition, o1-mini scored 70.0%, which is on par with the more expensive o1 model (74.4%) and significantly better than o1-preview (44.6%). This score puts o1-mini in the top 500 for US high school students, a remarkable achievement.
Coding
When it comes to coding, o1-mini excels on the Codeforces competition website, achieving an Elo score of 1650. This score is competitive with o1 (1673) and outperforms o1-preview (1258). This puts o1-mini in the 86th percentile of programmers competing on the Codeforces platform. Additionally, o1-mini performs well on the HumanEval coding benchmark and high school-level cybersecurity capture-the-flag (CTF) challenges, further cementing its coding prowess.
STEM
o1-mini has proven its worth on several academic benchmarks that require strong reasoning skills. On benchmarks such as GPQA (science) and MATH-500, o1-mini outperformed GPT-4o, demonstrating its excellence in STEM-related tasks. However, when it comes to tasks that require a broader range of knowledge, such as MMLU, o1-mini may not perform as well as GPT-4o. This is because o1-mini is optimized for STEM reasoning and may lack the broad world knowledge that GPT-4o possesses.
Evaluating human preferences
Human evaluators actively compared the performance of o1-mini to that of GPT-4o on challenging prompts across multiple domains. The results showed a preference for o1-mini in reasoning-intensive domains, but GPT-4o took the lead in language-focused areas, highlighting the models’ strengths in different contexts.
Security component in o1-mini
The safety and alignment of the o1-mini model are of utmost importance to ensure its responsible and ethical use. The security measures implemented are explained below:
- Training techniques: o1-mini’s training approach mirrors that of its predecessor, o1-preview, and focuses on alignment and safety. This strategy ensures that the model’s outputs align with human values and mitigate potential risks, a crucial aspect of its development.
- Jailbreak Robustness: One of the key security features of o1-mini is its improved robustness against information leaks. On an internal version of the StrongREJECT dataset, o1-mini demonstrates 59% higher robustness against information leaks compared to GPT-4o. Robustness against information leaks refers to the model’s ability to resist attempts to manipulate or misuse its outputs, ensuring that it remains aligned with its intended purpose.
- Security Assessments: Before implementing o1-mini, a thorough security assessment was conducted. This assessment followed the same approach used for o1-preview, which included preparedness measures, external teamwork, and comprehensive security assessments. External teamwork involves the involvement of independent experts to identify potential vulnerabilities and security risks.
- Detailed results: The results of these security assessments are published in the system card that accompanies the model. This transparency allows users and researchers to understand the model's security measures and make informed decisions about its use. The system card provides information about the model's performance, limitations, and potential risks, ensuring responsible deployment and use.
Final note
OpenAI’s o1-mini is a game-changer for STEM applications, offering cost-effectiveness and impressive performance. Its specialized training improves reasoning capabilities, particularly in math and coding. With robust security measures, o1-mini excels in STEM benchmarks and provides a reliable and transparent tool for researchers and educators.
