Microsoft to Integrate OpenAI's GPT-4.5 and GPT-5 Amidst AI Race with Google

Microsoft is preparing to integrate OpenAI's upcoming AI models, GPT-4.5 and GPT-5, anticipating their rollout by expanding server capacity. GPT-4.5, codenamed Orion, is expected to launch soon, with GPT-5 potentially debuting by late May. GPT-5 will integrate OpenAI's o3 reasoning model and aims to provide a seamless AI experience, eliminating the need for manual model selection in ChatGPT. Microsoft plans to launch GPT-5 integration around its Build developer conference on May 19, coinciding with Google I/O, setting the stage for a major AI showdown. Microsoft is also developing an AI agent similar to OpenAI's Operator, designed to automate web-based tasks. The company focuses on cost reduction and efficiency in its AI services, making them more attractive for enterprise customers.
