OpenAI CEO Sam Altman revealed that the company had to delay the rollout of its GPT-4.5 model due to an insurmountable GPU shortage. The new model is deemed "giant" and "expensive," requiring tens of thousands more GPUs before additional users can gain access. This raises concerns about the commercialization of AI technology and its impact on user accessibility. As a result, users may face significant delays or be forced to wait for extended periods before gaining access to the upgraded service. The situation highlights the challenges and limitations of developing and deploying large-scale AI models.
