What’s New in the o3 Series?
The most exciting addition to this family is the O3-pro model. It's designed to think harder and give more accurate answers for difficult problems. You can use it through the Responses API, which allows for smooth conversations between your app and the model over multiple steps.
Key Features of o3-pro
- Advanced Code Generation: It can write complex code, build algorithms, and help with tough programming tasks.
- Powerful Problem Solving: Perfect for brainstorming, troubleshooting, or tackling difficult technical and logical problems.
- Workflow Support: Great for following instructions and managing tasks, especially when the information is short and to the point.
- Flexible Input/Output: It works with both text and image inputs and gives back clear text-based responses.
- Structured Outputs: Supports function calling and returning results in a structured format.
Other Models in the O Series.
- o4-mini: The most efficient model for reasoning, now generally available. It’s great for agentic solutions.
- o3: The flagship model in the O3 series. It supports full tool integration and is excellent for creating intelligent solutions.
- o3-mini: A lighter, faster version of o3. It’s good for quick coding tasks where speed matters.
- o1 & o1-mini: These are earlier models focused on reasoning. o1 is more powerful, while o1-mini is faster and cost-friendly
