Golden Finance reported that OpenAI's System Card report stated that it is releasing a research preview version of OpenAI GPT-4.5, its largest and most knowledgeable model to date. Based on GPT-4o, GPT-4.5 further extends pre-training and is designed to be more general than its powerful stem inference model. Early testing showed that interacting with GPT-4.5 felt more natural. It has a broader knowledge base, is more in line with user intentions, has a higher emotional intelligence, so it is perfect for tasks such as writing, programming, and solving practical problems, and has fewer hallucinations.
