Recently, sources have revealed that Microsoft is actively preparing for the upcoming release of OpenAI's new models — GPT-4.5 and GPT-5. According to OpenAI's CEO Sam Altman, GPT-4.5 will be officially launched in a few weeks, with Microsoft expected to host this new AI model as early as next week. Codenamed "Orion," GPT-4.5 is OpenAI's next-generation model and will be the company's last non-chain-of-thought model. Industry insiders point out that the capabilities of GPT-4.5 are expected to significantly surpass those of its predecessor, GPT-4.

However, the current focus is not solely on GPT-4.5; Microsoft is also looking forward to the arrival of GPT-5. Reports indicate that GPT-5 is expected to be released by the end of May, aligning with Altman's previous commitment that this next-generation model would be launched within a few months. Notably, GPT-5 may undergo the most significant changes among these two models, as Altman describes it as “a system that integrates many of our technologies.” Additionally, GPT-5 will include OpenAI's newly introduced o3 reasoning model, which was previously hinted at during the Christmas event in December.
OpenAI recently released o3-mini but plans to no longer launch the o3 model separately; instead, it will be integrated into the GPT-5 system. This move reflects OpenAI's desire to consolidate its large language models with the ultimate goal of creating a more powerful model known as Artificial General Intelligence (AGI). The updated GPT-5 system will significantly enhance the user experience with ChatGPT, unifying OpenAI's o series and GPT series models, thereby reducing user confusion when selecting the appropriate model for specific tasks.
With the imminent release of GPT-4.5 and GPT-5, the rapid advancement of AI technology will further drive transformation across various industries.
