OpenAI has made a research preview of GPT-4.5, its most sophisticated chat model to date, available to developers and users globally for ChatGPT Pro. ChatGPT Pro subscribers are now able to choose GPT-4.5 in the model picker on web, mobile, and desktop.
We will start rolling out to Plus and Team users next week, then Enterprise and Edu users a week later," OpenAI said. The Sam Altman-led company called GPT-4.5 an important advancement in pre-training and post-training strategies. Through developing unsupervised learning methods, the model has enhanced its power to identify patterns, make connections, and create innovative insights, although it doesn't use reasoning.
Early tests show that conversations with GPT-4.5 are more natural and smoother. "Its larger knowledge base, better capacity for understanding user intent, and increased emotional intelligence make it useful for applications such as writing refinement, programming, and pragmatic problem-solving. We also expect a decline in hallucinations," OpenAI wrote in a blog post. "We're launching GPT-4.5 as a research preview to more accurately evaluate its capabilities and limitations.". We’re still exploring its full potential and are excited to see unexpected applications by users,” the company added.
Trained on Microsoft Azure AI supercomputers, GPT-4.5 offers a wider knowledge base and a deeper understanding of various subjects, leading to increased reliability and fewer hallucinations across diverse topics.
The model also has real-time access to current information through search, accommodates file and image uploads, and has a canvas tool for coding and writing work. Nevertheless, GPT-4.5 does not have multimodal features like Voice Mode, video, and screen sharing in ChatGPT. OpenAI has guaranteed users that updates in the future will be directed towards perfecting the AI experience so that it works seamlessly and effectively.
