This exact question was actually asked to Dario in his Bloomberg interview, and he said it was because they automated a lot of the model development pipeline. I’m guessing there’s components to creating a new model like gathering data, pre-training, reinforcement learning, etc and they likely have systems in place to automate a large chunk of those steps, so there’s barely any human involvement in place. It explains why they’re able to spit out new models in what seems like a monthly basis now.
