OpenAI has launched a research preview of its latest AI model, GPT-4.5, bringing improvements in reasoning, creativity, and accuracy. Available to ChatGPT Pro users and developers worldwide, the model will soon be accessible to ChatGPT Plus and Team users, followed by Enterprise and Edu users next week.

OpenAI, the company behind ChatGPT, has been at the forefront of artificial intelligence innovation. Founded in 2015, the organization has introduced several groundbreaking models, including GPT-3, GPT-4, and GPT-4o, each enhancing the ability of AI to generate human-like text, understand context better, and assist with complex tasks. GPT-4.5 represents the next leap in this evolution, refining AI’s pattern recognition, reducing hallucinations (incorrect or made-up responses), and demonstrating improved creative problem-solving.

One of the standout improvements in GPT-4.5 is its significantly lower hallucination rate. According to OpenAI, the new model has a hallucination rate of 37.1%, a notable drop compared to GPT-4o’s 61.8% and the o1 reasoning model’s 44%. This means GPT-4.5 is more reliable when generating factual information, making it a valuable tool for research, content creation, and professional use.

Despite its advancements, GPT-4.5 does not yet support voice or video capabilities. However, it does allow users to upload files and images, making it more versatile for writing, coding, and problem-solving tasks. This aligns with OpenAI’s broader vision of creating AI models that can seamlessly integrate into various professional and creative workflows.

OpenAI CEO Sam Altman described GPT-4.5 as “a giant, expensive model,” emphasizing that GPU shortages have been a major challenge in its rollout. “We will add tens of thousands of GPUs next week,” Altman shared on X, acknowledging the difficulty in predicting demand surges that put pressure on hardware availability.

The release of GPT-4.5 reinforces OpenAI’s leadership in the AI space, coming just months after the launch of GPT-4o. As competition in AI continues to grow, OpenAI remains focused on pushing the boundaries of what AI can achieve, making it smarter, more reliable, and accessible to a wider audience.

With AI becoming increasingly integrated into everyday life—from content creation to business operations—models like GPT-4.5 are shaping the future of how we interact with technology. As OpenAI continues its research and expansion, users can expect even more powerful AI tools in the near future.
