OpenAI has just dropped o3-mini, a new, more affordable reasoning model that’s now available for both ChatGPT and the OpenAI API. This release follows a December preview among other things, and comes as OpenAI seeks to maintain its competitive edge against Chinese AI company DeepSeek. o3-mini promises to shake up the AI landscape with its impressive capabilities and cost-effectiveness.
o3-mini: Reasoning Made Easier
OpenAI says o3-mini is better than other small, efficient models. It’s good at STEM subjects like science, math, and coding. It can search for up-to-date answers and give you links to websites. This makes it great for research.
o3-mini is the first small reasoning model from OpenAI that can do things like function calling, Structured Outputs, and developer messages. You can choose from low, medium, or high reasoning effort. This means you can pick the best setting for what you’re doing. Use high for complex tasks and low for quick answers.
OpenAI still has o1 as its standard model. o3-mini is for technical stuff that needs speed and accuracy. ChatGPT uses medium reasoning effort with o3-mini by default. You can choose high if you need the extra power.
