We are witnessing real time of the evolution of artificial intelligence (AI). A little over two years ago we were surprised by the capacities of GPT-3.5the language model behind Chatgptnow we have Reasoning models increasingly powerful at hand. And everything seems to indicate that this industry will continue to evolve.
Early today we talked about Microsoft’s decision To make a version of O1 available to Copilot users, a product that had been limited to payment users. A few hours later we have received news from Openai, which A new reasoning model has just launched. It is tata from O3-mini, who has just begun its initial deployment.
O3-mini, the new OpenAI reasoning model
The latest OpenAi responds to a strategy that we have already seen with GPT-4o Mini. Instead that everything revolves around its flagship, the company promotes a series of models aimed at addressing different needs. In this way, O3-mini is part of the O3 family presented at the end of last yearbut it is focused on speed and efficiency.
It should be noted that those led by Sam Altman had already launched in September 2024, and decided to skip O2 apparently for reasons of registered trademarks. So now we are facing a proposal that promises not only for its fantastic scores in different tests, but because it lands in the chatgpt ‘free’ accounts, also in Spain.


But what does this mean? Well, reasoning models differ from the rest of the models, such as GPT-4for its ability to Verify thoroughly and step by step your answers. They channel our questions through a “reasoning.” This does not mean that they cannot be wrong, but the answers are much more successful.


Reasoning means time, so this type models are not particularly fast. In any case, for certain scenarios in which reasoned responses are needed in a reasonable amount of time, O3-mini could be a great option. For example, to boost certain applications thanks to access through the API.
O3-mini is a model that embraces Stem problems. That is, if what you are looking for is to perform a literary essay, this will probably not be the ideal model. Now, if your requests are related to Science, Technology, Engineering and Mathematics It is likely that this reasoning model can give you some more consistent responses to your needs.
OpenAI has measured the reaction of users with O3-mini and O1-mini. According to their data, external testers opted for the responses of the most recent model. In addition, O3-Mini reduced the “important errors” in the “difficult questions of the real world” in 39% during A/B tests, surpassing O1-mini. A notable fact for free access.
If you have one Pro $ 200 per month You can use the model unlimitedly ” and with a higher speed than free accounts. OpenAI also has a business plan, Chatgpt Enterprise. In this case, users will have to wait until next week to use the company’s latest reasoning model.
