Microsoft is gearing up to support OpenAI’s upcoming AI models, GPT-4.5 and GPT-5, with preparations underway to enhance server capacity. A source close to the situation revealed that GPT-4.5, codenamed Orion, is expected to launch as early as next week. OpenAI’s CEO, Sam Altman, has confirmed that GPT-4.5 will be released soon, promising advancements over its predecessor, GPT-4. This model is seen as the last of its kind before OpenAI transitions to more complex systems.
Looking ahead, Microsoft anticipates the arrival of GPT-5 around late May, aligning with Altman’s indication that the next-generation model will be available in the coming months. However, this timeline could change based on development progress. Initially, OpenAI had aimed for a 2024 release for GPT-4.5, but plans shifted to early 2025.
GPT-5 is expected to be a major upgrade, integrating various technologies developed by OpenAI. This model will feature the new o3 reasoning model, which was highlighted during OpenAI’s announcements in December. Although OpenAI recently released o3-mini, the company has decided not to offer o3 as a standalone model; instead, it will be part of the GPT-5 system. This move is part of OpenAI’s broader vision to merge its large language models into a single, more advanced system, potentially leading to the creation of artificial general intelligence (AGI).
The upcoming GPT-5 will also enhance the user experience with ChatGPT by unifying the o-series and GPT-series models. This integration aims to simplify the selection process for users, making it easier to choose the right model for various tasks and queries. As Microsoft prepares to host these advanced models, the tech community eagerly awaits the innovations they will bring.
