Microsoft is gearing up to host OpenAI's upcoming AI models, GPT-4.5 and GPT-5, with the former expected to debut next week. OpenAI CEO Sam Altman mentioned that GPT-4.5 will be significantly more powerful than its predecessor, GPT-4, while also hinting at the advancements in GPT-5, set for release in late May. GPT-5 aims to integrate OpenAI's new o3 reasoning model and improve user interactions with ChatGPT, moving toward goals of enhanced capability potentially leading to artificial general intelligence (AGI).
Codenamed Orion, GPT-4.5 is OpenAI's next frontier model and the company's last non-chain-of-thought model.
While OpenAI released o3-mini last month, OpenAI is no longer planning to ship o3 as a standalone model.
