OpenAI rolls out GPT-4.5 for some paying users, to expand access next week

ChatGPT developer OpenAI said on Thursday it has released a research preview of its latest GPT-4.5 model for its Pro users and developers worldwide, with plans to expand access in the coming weeks. GPT-4.5 comes with improved ability to recognise patterns, generate creative insights without reasoning and shows greater emotional intelligence, the company said. Microsoft-backed OpenAI said it would begin rolling out GPT-4.5 to ChatGPT Plus and Team users next week, and then to Enterprise and Edu users the following week. this isn't how we want to operate, but it's hard to perfectly predict growth surges that lead to GPU shortages," he said in a post on X. OpenAI said the model also has a lower rate of "hallucinations", a common issue in which large language models generate false information.
