OpenAI's GPT-4.5 Turbo has been unexpectedly revealed and is expected to launch in June. GPT-4.5 Turbo is described as OpenAI's fastest, most accurate, and most scalable model to date, featuring a context window of 256,000 tokens. It may have video or 3D capabilities, although this was not mentioned in the leaked information.

Recently, OpenAI conducted beta testing for GPT-4.5 Turbo, with bloggers such as Baoyu and Guicang updating to the latest version. GPT-4.5 Turbo shows significant improvements in generation quality, response speed, contextual understanding, and multimodal capabilities. Safety has been further enhanced, with improved filtering for inappropriate content, reducing the risk of misuse. The efficiency of programming and code generation has notably increased, and personalization and customization capabilities have become more refined. Compared to GPT-3.5 and GPT-4, GPT-4.5 Turbo excels in multiple areas.

OpenAI CEO Sam Altman denied the release of the new version of GPT-4.5. The leaked screenshots circulating on social media have been confirmed to be false. It is still unclear whether OpenAI will release GPT-4.5 or upgrade directly to GPT-5. Microsoft is considering joining the OpenAI board after Sam Altman's return.
