Sam Altman, CEO of OpenAI, has announced an unexpected challenge for the launch of its most advanced artificial intelligence model, GPT-4.5. Although the model is ready to be implemented, OpenAI is facing a critical shortage of GPUs, which has delayed its full deployment. According to Altman, the model is so large and expensive that its current infrastructure does not have enough capacity to keep scaling, which directly impacts the availability of GPT-4.5 for Plus and Pro subscribers.
In a message posted through his official account on X, Altman explained that, despite the intention to offer the model to Plus and Pro subscribers simultaneously, the shortage of NVIDIA graphics cards has hindered its expansion. However, the OpenAI CEO was optimistic, stating that next week they will receive “tens of thousands of GPUs” to provide access to GPT-4.5 at the Plus subscription level. He cautioned, however, that more hardware would still be necessary to meet the growing demand for the model.
GPU Shortage: A Widespread Problem?
The GPU shortage is not a problem exclusive to OpenAI. This situation affects multiple sectors, not just artificial intelligence but also the video game market, where the GeForce RTX 50 Series graphics cards are experiencing availability issues. The fact that NVIDIA, the leading supplier of graphics chips, cannot meet OpenAI’s demand is due to its business model, where the company has to allocate its resources among all its customers without prioritizing any specific company.
Although OpenAI relies on NVIDIA to power its data centers with the DGX B200 and DGX H200 platforms, Altman acknowledged that they are working to reduce this dependency. The CEO noted that OpenAI has started developing its own artificial intelligence chip, following the trend of other major tech companies like Amazon, Google, and Microsoft, which are investing in creating exclusive hardware to meet their own AI needs and reduce the impact of the shortage.
The Future of GPT-4.5: More Users Benefited
Despite the delays, GPT-4.5 continues to generate expectations, especially due to its improved ability to provide more natural and useful interactions. According to Altman, users have begun experimenting with GPT-4.5 and have noticed a significant difference in the quality of responses. The CEO mentioned that it is the first model with which he truly feels like he is “talking to a thoughtful person,” citing moments of astonishment at receiving accurate advice from the artificial intelligence.
The lack of GPUs has complicated OpenAI’s operations, but the company is working to resolve these obstacles as quickly as possible. According to Altman, the firm intends to make access to GPT-4.5 available to more users once they can ensure a sufficient quantity of chips. Additionally, with the growing availability of GPUs, the company plans to expand its access, allowing more people to benefit from the latest version of its advanced AI model.
Sam Altman’s Comments on the Situation:
“Good news: GPT-4.5 is the first model that makes me feel like I’m talking to a thoughtful person. I’ve had several moments where I’ve sat in my chair and been amazed at receiving really good advice from an AI.”
“Bad news: it is a gigantic and expensive model. We wanted to launch it for ChatGPT Plus and Pro at the same time, but we’ve been growing a lot and have run out of GPU. Next week we’ll add tens of thousands of GPUs and launch it for Plus (soon there will be hundreds of thousands, and I’m pretty sure you will use all that we can accumulate).”
“This is not how we want to operate, but it is difficult to perfectly predict growth spikes that cause GPU shortages.”
Conclusion: Challenges and Opportunities on the AI Horizon
The GPU shortage has highlighted the difficulties OpenAI faces in rapidly scaling its infrastructure to meet the demande for advanced models like GPT-4.5. While this challenge could slow down widespread access to the model, it also underscores the need for innovation in creating proprietary hardware for artificial intelligence, a trend that could change the landscape for companies like OpenAI in the future.
As technology continues to advance, more users around the world are expected to access the enhanced capabilities of GPT-4.5. However, for now, OpenAI is facing a resource availability challenge that could mark a new stage in the relationship between chip suppliers and artificial intelligence companies.
