OpenAI introduces GPT-4.5 AI model with more personality and natural-feeling conversations
The race to make the best AI assistant is red-hot right now as an increasing number of companies strive to capture a captivated audience. Hot off the heels of Grok 3 beta launching in the middle of last week, OpenAI has this week released a research preview of GPT-4.5, the latest and greatest of the company’s chat-based AI model to date.
In a blog post, OpenAI says that GPT-4.5 makes major leaps in how the model gets trained, making it much more powerful in terms of creativity, pattern recognition, and connecting the dots between alike ideas. Moreover, it can appearing more “natural” to the person interacting with it. That’s because it can follow along with the user’s needs better than previous iterations could, giving it improved personality.
OpenAI explains that because of this deeper understanding, GPT-4.5 can interpret what humans mean from subtle cues and implicit expectations with greater nuance. Its deeper world knowledge also makes it more fun to talk to than reasoning models like GPT-o1 and o3-mini. That’s because reasoning models have much less personality – they ‘think’ about their output more to provide a methodical output.
Instead of being direct and to the point as reasoning models are, GPT-4.5 make seem more creative. The output won’t be as detailed or methodical as they are from reasoning models, but the more natural fluency can feel more relatable.
In the long term, OpenAI hopes to combine the strengths of ‘creative’ models with ‘reasoning’ models to offer a more complete product, which will be a great performer all around rather than in particular areas.
Because GPT-4.5 is currently a research preview, users should understand that their text inputs may be used for product improvement. Notably, OpenAI wants to learn more about the model’s strengths and weaknesses and hopes that end users will assist them in doing just that.
GPT-4.5 is available to ChatGPT Pro users starting today and can be selected from the model picker available in the mobile and desktop apps, as well as on the web. It will then roll out to Plus and Team users next week before rolling out to Enterprise and Edu users the week after.
