Wan 2.5 is the widest generation this workspace exposes — text to video, image to video, text to image, image editing and video extension. On Hugging Face that same generation arrives as weight files plus the config and tokeniser needed to run them yourself. wan2-6.net does not host those repositories and does not distribute weights; what it does is run the routes on your behalf. This page is the honest comparison.
A later generation usually means more parameters and a larger feature surface, and both push the same direction: more VRAM for the same clip. If your card was comfortable with an earlier generation, that is not a promise it will be comfortable with this one at the same resolution and duration.
That is the trap with version numbers. The new generation may well produce better results and still be the wrong choice for your machine, because the limiting factor is not which model is better in the abstract — it is which one fits.
The honest case for hosting is not "it is better" — it is that the setup cost is paid before you learn whether the model suits your material. On the hosted route the credit cost of a run is shown beside the form before you submit, so the first useful information you get is whether the output is any good, not whether your environment compiles. Credit prices are on pricing.
If you want the wider comparison of local versus hosted, Wan 2.2 GGUF covers the format question and Wan 2.2 Hugging Face covers repositories in general.
Start from the Wan 2.5 model page for what this generation exposes, or the Wan workspace for the live routes. Model names and settings are shown in the form, and the live controls are the source of truth rather than any list on a page.
Can I download Wan 2.5 from this site? No. This site runs the model for you.
Is Wan 2.5 better than 2.2? For many shots, probably; for your specific card at your specific resolution, not necessarily. Compare at a fixed seed rather than trusting the version number.
Does a hosted run use the same files as the repository? Not guaranteed — check the routes named in the live form.
Which route should I try first? If your idea starts from a still image, image to video usually gets to a usable result fastest.
