Hosted instead of self-hosted

Running an open model yourself costs the GPU, the setup time and the electricity. On Reviral the Wan family is hosted: Wan 2.6 renders 5, 10 or 15 seconds at 720p or 1080p for 83 credits (~$1.04) per 5 seconds, and Wan 3.0 renders 2 to 30 seconds for 99 credits (~$1.24) per 5 seconds.

These hosted versions are newer Wan releases served from the cloud. For weights on your own machine, the Wan 2.2 release above is the open one.
