Wan3.0 launches: video generation shifts from toy to tool

Friends around me have been spreading news about Alibaba's video large model Wan3.0 launching these past two days, saying it can generate 30-second videos in one go and even take PPTs and docs directly as input to convert them. My first thought was about the duration, and only then did I think about document input. But it turned out to be the other way around; what really made me ponder for half a day was that document input feature.
