OpenAI has launched GPT-4.5, its most advanced language model, described by CEO Sam Altman as feeling like conversing with a thoughtful person. It is designed for various tasks, including writing and programming, and is currently available in a research preview for ChatGPT Pro users. The model focuses on unsupervised learning to enhance word knowledge, intuition, and reduce hallucinations. Its greater contextual understanding makes it a better conversationalist compared to previous models, highlighting OpenAI's commitment to advancing AI in a more general-purpose direction.
"The first model that feels like talking to a thoughtful person to me. I have had several moments where I've sat back... getting actually good advice from an AI."
"We really wanted to launch it to plus and pro at the same time, but... out of GPUs. We will add tens of thousands of GPUs next week..."
"...focusing on scaling up models on word knowledge, intuition, and reducing hallucinations... is the latest advancement of OpenAI's unsupervised learning paradigm."
"In practice, GPT-4.5 is the most natural conversationalist... it responds more adeptly to social cues than OpenAI's STEM-focused reasoning model."
