On February 28, OpenAI officially released its latest GPT-4.5 AI model through its official blog. The model is praised by OpenAI as the largest and best-performing chat model to date, and is the first to open the experience to ChatGPT Pro users in the form of a research preview. This release marks a new milestone in artificial intelligence technology.
GPT-4.5 has significantly expanded on pre-training and post-training scales, an improvement that directly enhances its unsupervised learning capabilities. According to OpenAI, the model has made breakthrough progress in understanding complex patterns, building logical connections, and generating creative content. Early test feedback showed that the interactive experience with GPT-4.5 was more natural and smooth, its knowledge base covers a wider range, and a deeper understanding of user intentions. In addition, GPT-4.5 has performed particularly well in "emotional intelligence", which can effectively improve writing, programming skills and ability to solve practical problems, while significantly reducing the occurrence of "illusion" phenomena and further improving the reliability of the model.
GPT-4.5 further improves the ability to non-supervised learning by expanding the scale of computing and data, optimizing architecture, and introducing innovative technologies. Its broader knowledge reserves and deep understanding of the world provide users with a more accurate and reliable interactive experience. At the same time, the superb skills shown by GPT-4.5 in understanding user intentions and its effectiveness in reducing "illusion" phenomena have brought this model to a new level in reliability.
It is worth mentioning that GPT-4.5 adopts new scalable technology, which can use the data of smaller models to train larger and more powerful models. The introduction of this technology has improved GPT-4.5 in terms of controllability, understanding of nuances and natural dialogue capabilities. In the fields of writing and design, GPT-4.5 also performs well, showing strong creativity and aesthetic intuition, and providing users with richer creative tools.
GPT-4.5 has a wide range of application scenarios, including but not limited to areas such as writing assistance, communication, learning, guidance and brainstorming that require higher emotional intelligence and creativity. In addition, the model also demonstrates strong capabilities in agent planning and execution, supporting multi-step coding workflows and automated processing of complex tasks, providing more efficient solutions for both enterprise and individual users.
Although GPT-4.5 is a huge and compute-intensive model that costs more than GPT-4, OpenAI said they are evaluating whether they will provide GPT-4.5 services in the API for a long time. It is reported that GPT-4.5 will be launched first for Pro users, and will then be promoted to Plus and Team users next week, and then gradually expanded to Enterprise and Edu users. It is worth noting that users are now trying to use GPT-4.5 on Microsoft's Azure AI Foundry platform, which provides more users with the opportunity to experience this advanced technology.
