We are pleased to announce that OpenAI’s new o3-mini model is now available in Microsoft Azure OpenAI Service. Building on the foundation of the o1 model, o3-mini delivers a new level of efficiency, cost-effectiveness, and reasoning capabilities.
We are pleased to announce that OpenAI o3-mini is now available in Microsoft Azure OpenAI Service. o3-mini adds significant cost efficiencies compared with o1-mini with enhanced reasoning, with new features like reasoning effort control and tools, while providing comparable or better responsiveness.
o3-mini’s advanced capabilities, combined with its efficiency gains, make it a powerful tool for developers and enterprises looking to optimize their AI applications.
With faster performance and lower latency, o3-mini is designed to handle complex reasoning workloads while maintaining efficiency.
New features of o3-mini
As the evolution of OpenAI o1-mini, o3-mini introduces several key features that enhance AI reasoning and customization:
Reasoning effort parameter: Allows users to adjust the model’s cognitive load with low, medium, and high reasoning levels, providing greater control over the response and latency.
Structured outputs: The model now supports JSON Schema constraints, making it easier to generate well-defined, structured outputs for automated workflows.
Functions and Tools support: Like previous models, o3-mini seamlessly integrates with functions and external tools, making it ideal for AI-powered automation.
Developer messages: The “role”: “developer” attribute replaces the system message in previous models, offering more flexible and structured instruction handling.
System message compatibility: Azure OpenAI Service maps the legacy system message to developer message to ensure seamless backward compatibility.
Continued strength on coding, math, and scientific reasoning: o3-mini further enhances its capabilities in coding, mathematics, and scientific reasoning, ensuring high performance in these critical areas.
With these improvements in speed, control, and cost-efficiency, o3-mini is optimized for enterprise AI solutions, enabling businesses to scale their AI applications efficiently while maintaining precision and reliability.
From o1-mini to o3-mini: What’s changed?
o3-mini is the latest reasoning model released, with notable differences compared with the o1 model released last September. While both models share strengths in reasoning, o3-mini adds new capabilities like structured outputs and functions and tools, resulting in a production-ready model with significant improvements in cost efficiencies.
