Video models that run on 64 GB

28 models with published weights that fit in 64 GB — a workstation. Counted at four-bit quantisation, weights only, leaving the machine about a third of its memory and a gigabyte for context: room for roughly 67 billion parameters. A mixture of experts is counted in full, because it is held in full even though only a few experts compute.

A workstation, or a well-specified Mac. Seventy-billion-parameter models fit at four-bit, which is the class where local output stops being obviously worse than the hosted models people pay for. Loading takes real time and the machine will be warm.

Models that generate moving footage, most of them now with sound. Priced by the second of output, sometimes doubled for higher resolution, which makes this the most expensive thing in the catalogue to experiment with — a minute of 1080p can cost more than a million tokens of text. Check the maximum clip length and whether it will continue from an image you supply.
