More research from the team


Our founding team met as PhDs at the Stanford AI Lab, where we invented State Space Models or SSMs, a fundamental new primitive for training large-scale foundation models. Over the past four years, we’ve built the theory behind SSMs and scaled it up to achieve state-of-the-art results in modalities as diverse as text, audio, video, images, and time-series data.
