What's this about?
Simon Willison generated video from MiniMax-H3 entirely on his own M5 Pro Mac — prompt: "a rainbow colored skunk leaps over a mossy log in a supermarket." The catch: ~115GB model download and ~45 minutes per clip.
What exactly is "local video generation"?
Running the whole video model on your own machine, with nothing sent to a server. Yesterday's news was that H3 is open-weights; today's proof point is that a consumer Mac can actually run it — slowly, hugely, but for real and for free.
