According to TomsHardware , the CEO of OpenAI just announced on the X platform (formerly Twitter) that the company is having to delay the expansion of GPT-4.5 due to the shortage of GPUs (graphics cards). OpenAI plans to add tens of thousands of GPUs next week to deploy this model to Plus users for $ 20 / month. He also confirmed that hundreds of thousands of GPUs will be added in the near future.

The GPU shortage isn’t just an OpenAI problem; it reflects the growing demand for AI hardware. To reduce its reliance on outside suppliers like Nvidia, OpenAI has partnered with Broadcom to develop its own line of AI chips. But it will be years before the company can produce its own chips. For now, OpenAI will rely on Nvidia and other suppliers to keep its operations running.
Nvidia is benefiting from the wave of AI investment, with the company confirming that its latest Blackwell GPUs are fully booked through October. Demand is also being driven by massive data center expansion plans around the world. For example, OpenAI and Microsoft are teaming up to build a $100 billion AI supercomputer, while billionaire Elon Musk wants to expand the Colossus supercomputer in Memphis, Tennessee, to more than a million GPUs.
Many investors are also focusing on AI infrastructure. The South Korean government has just approved a 3GW (gigawatt) data center project, while another research group is testing data storage on the Moon . However, Microsoft CEO Satya Nadella warned that humans are building too many AI systems while models are becoming more advanced and consuming more resources.
GPT-4.5 is a clear example of this trend. According to Open AI CEO Sam Altman, this is a "huge and expensive" model, with usage costs of up to $75 for each million input tokens and $150 for each million output tokens. Meanwhile, GPT-4o - another OpenAI model - costs only $2.50 and $10 for the corresponding levels. However, Altman said that GPT-4.5 does not focus on reasoning ability or high performance on tests, but instead provides a different type of intelligence such as "emotional intelligence".
