OpenAI has unveiled GPT-4.5, its most expansive AI model yet, code-named Orion. The new release marks a significant milestone in the evolution of the company’s language models, boasting increased computing power and a more extensive dataset than any previous version.
In a recent announcement, CEO Sam Altman highlighted the challenges encountered during the model’s rollout. “We had to stagger the rollout because we were literally out of GPUs,” Altman said, underscoring the unprecedented scale and computational demands of GPT-4.5. Early access to the model is currently available as a research preview for subscribers to the $200-a-month ChatGPT Pro plan. Meanwhile, users on ChatGPT Plus and ChatGPT Team plans are expected to receive access next week.

As part of a broader industry trend toward larger, more capable AI systems, GPT-4.5 is set to fuel advancements in both academic research and commercial applications.
The launch of GPT-4.5 comes amid a dynamic period in the tech sector, with significant developments unfolding across various areas of artificial intelligence. As OpenAI continues to push the boundaries of what is possible with large language models, industry observers will be watching closely to see how these innovations influence the rapidly evolving AI landscape.
