Rumored GPT-4.5 Release Could Arrive Next Week, GPT-5 Expected by May

OpenAI’s next AI models, GPT-4.5 and GPT-5, are reportedly nearing release, with Microsoft preparing server capacity for their launch.

GPT-4.5, codenamed 'Orion,' is rumored to launch as early as next week, though OpenAI has not confirmed a specific release date.
Microsoft is reportedly readying its servers to host GPT-4.5 and GPT-5, with the latter anticipated for release in late May 2025.
OpenAI CEO Sam Altman described GPT-4.5 as the company's 'last non-chain-of-thought model,' with GPT-5 aiming to integrate multiple AI tools and reasoning capabilities.
GPT-5 is expected to include OpenAI's o3 reasoning model, enhancing fact-checking and decision-making processes, and to offer unified intelligence across tasks.
The potential May release of GPT-5 aligns with major tech events, including Microsoft's Build and Google I/O developer conferences.
