Declaring that the o3-mini reasoning model is now accessible through Microsoft Azure OpenAI Service
Microsoft Azure OpenAI Service now offers OpenAI o3-mini. With improved reasoning and additional capabilities like reasoning effort control and tools, the o3-mini offers equivalent or superior responsiveness with significant cost savings over the o1-mini.
O3-mini is a potent tool for developers and businesses wishing to maximise their AI applications because of its sophisticated features and efficiency improvements.
O3-mini is made to manage complex reasoning workloads with efficiency with its faster speed and lower latency.
New O3-mini features
As OpenAI o1-mini develops, o3-mini adds a number of crucial elements that improve AI customisation and reasoning:
- Reasoning effort parameter: Gives users more control over response and latency by allowing them to modify the model’s cognitive load with low, medium, and high reasoning levels.
- Outputs that are well-defined and organised are now easier to produce for automated workflows thanks to the model’s support for JSON Schema constraints.
- Support for Functions and Tools: O3-mini is perfect for AI-powered automation because, like earlier models, it easily connects with functions and external tools.
- Messages from developers: In earlier generations, the system message was replaced with the “role”: “developer” property, which provides more organised and flexible handling of instructions.
- System message compatibility: To guarantee smooth backward compatibility, Azure OpenAI Service converts legacy system messages to developer messages.
- Ongoing strength in coding, arithmetic, and scientific reasoning: O3-mini keeps improving its coding, math, and scientific reasoning skills, guaranteeing superior performance in these crucial domains.
O3-mini is optimised for enterprise AI solutions with these speed, control, and cost-efficiency gains, which let companies scale their AI applications effectively without sacrificing accuracy and dependability.
What has changed from o1-mini to o3-mini?
The most recent reasoning model, o3-mini, differs significantly from the o1 model, which was released in September of last year. Although the reasoning behind both models is strong, o3-mini adds new features including structured outputs, functions, and tools, making it a production-ready model with notable cost efficiency gains.

Reasoning Effort Control | No | Yes (low, medium, high) |
Developer Messages | No | Yes |
Structured Outputs | No | Yes |
Functions/Tools Support | No | Yes |
Vision Support | No | No |
OpenAI o3-mini
The newest and most affordable model in OpenAI’s reasoning series, OpenAI o3-mini, is being made accessible today via ChatGPT and the API. This strong and quick model, which was previewed in December 2024, pushes the limits of what small models can accomplish. It maintains the low cost and lower latency of OpenAI o1-mini while delivering remarkable STEM capabilities, with a focus on science, math, and coding.
OpenAI’s first compact reasoning model, OpenAI o3-mini, is production-ready right out of the box with its support for developer features like function calling, structured outputs, and developer messaging. o3-mini will offer streaming, same like OpenAI o1-mini and OpenAI o1-preview. Additionally, developers can optimise for their particular use cases by selecting from three reasoning effort options: low, medium, and high.
Because of its adaptability, o3-mini can “think harder” while solving challenging problems or give priority to speed when latency is an issue. Since o3-mini lacks vision capabilities, developers should keep using OpenAI o1 for workloads requiring visual reasoning. Starting today, o3-mini will be made available to a limited number of developers at API usage levels 3-5 in the Chat Completions, Assistants, and Batch APIs.
OpenAI o3-mini is now available to ChatGPT Plus, Team, and Pro users; Enterprise access will be available in February. With its increased rate limits and reduced latency, o3-mini will take the place of OpenAI o1-mini in the model picker, making it an attractive option for tasks involving coding, STEM, and logical problem-solving. The rate limit for Plus and Team customers will be tripled as part of this upgrade, going from 50 messages per day with o1-mini to 150 messages per day with o3-mini. Furthermore, o3-mini now integrates search to locate current responses along with links to pertinent online resources. As it strive to incorporate search into all of its reasoning models, this is an early version.
OpenAI o3-mini is also available to free plan users as of right now by choosing “Reason” in the message composer or by regenerating a response. This is the first time that ChatGPT’s free users can access a reasoning model.
OpenAI o3-mini offers a specialised substitute for technical domains that demand accuracy and speed, while OpenAI o1 continues to be its more general knowledge reasoning model. O3-mini employs medium reasoning effort in ChatGPT to offer a fair trade-off between accuracy and speed. For a higher-intelligence variant that takes a little longer to produce responses, all premium customers will also be able to choose o3-mini-high in the model picker. Pro users can access both o3-mini and o3-mini-high indefinitely.
Powerful, quick, and tailored for STEM reasoning
OpenAI o3-mini has been tuned for STEM thinking, just as its OpenAI o1 predecessor. With a medium level of reasoning effort, o3-mini performs on par with o1 in science, math, and coding while producing quicker answers. Expert testers’ assessments revealed that OpenAI o3-mini outperforms OpenAI o1-mini in terms of reasoning skills and generates more precise and understandable responses. Testers saw a 39% decrease in major errors on challenging real-world questions and 56% preference for o3-mini solutions over o1-mini responses. On the most difficult reasoning and intelligence tests, such as AIME and GPQA, o3-mini performs on par with o1 with a medium level of reasoning effort.
Model performance and speed
OpenAI o3-mini offers enhanced efficiency and faster performance with intelligence on par with OpenAI o1. In addition to the STEM assessments mentioned above, o3-mini performs exceptionally well on other maths and factuality tests with a medium level of thinking effort. With an average reaction time of 7.7 seconds as opposed to 10.16 seconds, o3-mini outperformed o1-mini by 24% in A/B testing.
Security
Deliberative alignment, in which the model is trained to reason about human-written safety standards before to responding to user inputs, is one of the primary strategies it employed to educate OpenAI o3-mini to reply safely. Like OpenAI o1, it found that o3-mini performs noticeably better than GPT-4o on difficult safety and jailbreak tests. It meticulously evaluated the safety concerns of o3-mini before to deployment, employing the same strategy for readiness, external red-teaming, and safety assessments as o1. The safety testers that applied to test the o3-mini during early access are appreciated.
What comes next?
Another milestone in OpenAI’s quest to advance the limits of affordable intelligence has been reached with the introduction of OpenAI o3-mini. OpenAI is making high-quality AI even more accessible by minimising costs and optimising reasoning for STEM fields. Since the release of GPT-4, it has reduced the cost of intelligence by 95%, and this model keeps up its reputation for doing so while retaining superior reasoning capabilities. It is still dedicated to being at the forefront of AI adoption and creating models that strike a balance between safety, efficiency, and intelligence on a large scale.
