What commenters say

  • The model requires significant memory, but some users have successfully run it on devices with 64GB or 96GB of memory.
  • The model's performance is highly dependent on the specific settings and hardware used, with some users reporting significant speedups on certain devices.
  • Some users have developed workarounds to run the model on devices with limited memory, such as using quantized layers or streaming weights from disk.
  • The model's quality is considered to be high, with some users comparing it favorably to other private video models.
  • The use of unified memory systems can limit the benefits of certain optimizations, such as weight streaming, but can still provide significant performance improvements.
  • The model is primarily compute-bound, making it less ideal for devices with limited computational power, such as Macs.
