Model Training and Data Set Curation
The development of video models at Luma Labs relies heavily on meticulous data set curation and efficient learning algorithms. Training models like Dream Machine and Ray 2 requires a foundational understanding of the training data, which includes both traditional and unconventional visuals. By focusing on effectively curating these data sets, Luma builds models that can generalize and learn new concepts—like complex camera motions—efficiently. This emphasis on quality over quantity ensures that the model not only performs well from the outset but also continues to improve with each iteration.
