>"the company’s CEO, Sam Altman, says further progress will not come from making models bigger. “I think we're at the end of the era where it's going to be these, like, giant, giant models,” he told an audience at an event held at MIT late last week. “We'll make them better in other ways.”

So to reiterate, he is not saying that the age of giant AI models is over. Current top-of-the-line AI models are giant and likely will continue to be. However, there's not point in training models you can't actually run economically. Inference costs need to stay grounded which means practical model sizes have a limit. More effort is going to go into making models efficient to run even if it comes at the expense of making them less efficient to train.
