OpenAI Unveils GPT-4.5: More Human-Like Conversations, Smarter AI

OpenAI has officially launched GPT-4.5, its latest and most advanced AI model for chat-based applications. The company describes GPT-4.5 is told to be its “best model yet,” with even better scaling in unsupervised learning. This evolution enables the model to better detect patterns, create connections, and generate deeper insights.

OpenAI Launches GPT-4.5: Smarter AI with Better Conversations, Enhanced Creativity, and Improved Understanding

GPT-4.5 has a much more natural conversation experience and a better personality that allows it to navigate through ideas and steps to solutions better. In fact, it outperforms GPT-4o in many domains, including general knowledge questions, work tasks, and creative reasoning. OpenAI claims the new model has increased knowledge depth, better intent recognition, and an increased EQ, (emotional quotient) so it will be particularly useful for writing, programming, and real-world problem-solving. Additionally, GPT-4.5 should hallucinate much less than previous models.

This gives users a more intuitive and human-like experience, akin to GPT-4.5 has better well-developed intuition for reading subtle cues and implicit expectations. OpenAI emphasizes that the model is general-purpose and does not replace educational reasoning models like o1 or o3-mini. While reasoning models are useful for use bets like coding and maths, in the case of GPT-4.5 is more general in common day-to-day tasks as they are finetuned after the pretraining and then again after the training on a wide variety of datasets.

As of February 27, GPT-4.5 is making its way to Pro users today, and Team and Plus users can hop on next week. OpenAI will also make its way to Education and Enterprise customers in the next few weeks. Any developer with a paid tier subscription can access GPT-4.5 immediately. It can also help with writing and coding tasks and supports file and image uploads. However, it does not include support for Voice Mode, video processing, or screen sharing. Despite these constraints, the company claims that GPT-4.5 is going to be far more sophisticated and human in nature.
