Islamabad, Feb 1: OpenAI has unveiled its latest model, the o3-mini, on Friday, introducing a significant enhancement to ChatGPT. This new reasoning model is now accessible to all users, including those on the free tier, for the first time. To use it, ChatGPT users simply need to click the “Reason” button in the message interface, offering a more powerful tool for problem-solving and complex reasoning.
The o3-mini model has shown impressive performance in internal testing, processing responses 24% faster than the previous o1-mini model. When set to a “medium” reasoning effort, the o3-mini delivers results comparable to OpenAI’s more premium o1 system across technical fields such as mathematics, programming, and science.

Early benchmarking results suggest that the o3-mini excels in specialized technical fields, nearly matching the performance of its higher-end counterparts when handling complex computational and analytical tasks. This improvement positions the o3-mini as a highly efficient, cost-effective option for users looking to tackle intricate queries.
What makes the o3-mini particularly notable is its transparent reasoning feature. Unlike the traditional ChatGPT, which simply provides finished answers, the o3-mini allows users to trace how the model develops its responses. This feature provides valuable insight into the AI’s thought process, making it a potent tool for users seeking to understand the model’s reasoning.
In addition to the transparent reasoning, OpenAI has integrated ChatGPT Search into the o3-mini, enabling built-in web search functionality. This feature, which is set to be rolled out across OpenAI’s entire suite of reasoning models, adds a new layer of convenience for users seeking up-to-date information.
With the o3-mini now replacing the o1-mini in the selection menu, OpenAI has also announced a 3x increase in daily message limits for ChatGPT Plus and Team subscribers, rising from 50 to 150 messages per day. For those desiring unlimited access to the new system, the premium Pro tier remains available at $200 per month.
This release follows closely on the heels of DeepSeek’s launch of its latest AI model, which has shaken up the industry with aggressive pricing and an open-source approach. As the competition heats up, OpenAI’s move to make the o3-mini more accessible signals its commitment to enhancing AI-driven reasoning tools across the board.
