In BriefPosted:12:21 PM PST February 27, 2025Image Credits:Eugene Gologursky / Getty Images for the New York TimesOpenAI CEO Sam Altman says the company is out of GPUsOpenAI CEO Sam Altman said that the company was forced to stagger the rollout of its newest model, GPT-4.5, because OpenAI is out of GPUs.In a post on X, Altman said that GPT-4.5, which he described as giant and expensive, will require tens of thousands more GPUs before additional ChatGPT users can gain access. GPT-4.5 will come first to subscribers to ChatGPT Pro starting Thursday, followed by ChatGPT Plus customers next week. Perhaps in part due to its enormous size, GPT-4.5 is wildly expensive. OpenAI is charging $75 per million tokens (~750,000 words) fed into the model and $150 per million tokens generated by the model. Thats 30x the input cost and 15x the output cost of OpenAIs workhorse GPT-4o model. Weve been growing a lot and are out of GPUs, Altman wrote. We will add tens of thousands of GPUs next week and roll it out to the Plus tier then [] This isnt how we want to operate, but its hard to perfectly predict growth surges that lead to GPU shortages.Altman has previously said that a lack of computing capacity is delaying the companys products. OpenAI hopes to combat this in the coming years by developing its own AI chips, and by building a massive network of datacenters.Topics
