OpenAI o3 Overview

OpenAI o3 is the latest and most powerful AI inference model released by OpenAI from the end of 2024 to the beginning of 2025.

This is not a simple update, but aims to fundamentally improve the "thinking" ability of AI.

There are many breakthroughs in o3 , the most important two are:

1. Full-tool access and agent capability o3 can independently infer when and how to use a variety of tools such as web search, Python data analysis and file operations, and image generation available in ChatGPT, and use these tools together in the form of an agent to perform tasks for the first time ( full-tool access ).
2. Advanced image (visual) reasoning skills It not only understands text, but also has a deep understanding of visual information such as images and diagrams, and incorporates this information directly into the inference process. It can not only "see" the image, but also "think" the image, thus significantly improving the multimodal problem-solving ability.

With these abilities, o3 demonstrates outstanding performance in cutting-edge fields such as coding, mathematics, science and visual tasks .

【The successor of o3-mini】The high-speed, cost-effective "o4-mini"

The " o4-mini " released at the same time as o3 is the successor of the "o3-mini" that was once highly anticipated. It is a high-speed, cost-effective small AI model .

o3 pursues ultimate performance, while o4-mini is designed to allow more users to easily access and use AI.

Pricing and usage of OpenAI o3/o4-mini

The availability of OpenAI's o3 and o4-mini models is gradually expanding. The following will clearly explain access methods and pricing in ChatGPT, API, and Azure OpenAI Service.

O3 available solutions and usage limits

Currently, the free plan cannot use o3 , but the following plan can be used:

plan	Limitation of usage of o3 model
Plus/Team/Enterprise	100 messages per week
Pro Solution	Unlimited

【Free】Operational solutions and usage limits of o4-mini

o4-mini can be used in the following scheme:

Free users can select "Think" in the chat input interface (composer) to partially try o4-mini .

plan	Limitations of use of o4-mini	Limitations of use of o4-mini-high
Plus/Team/Enterprise	300 times a day	100 times a day
Pro Solution	Unlimited	Unlimited

✅ Plus/Pro/Team Users

You can use it by selecting " o4-mini " through the model selection button.

Model selection interface

? Enterprise/Edu users will be accessible soon.
