HunyuanVideo Is Here and Your H100 Is About to Get Very Busy
Tencent dropped fully open weights for a video model that can do 10 seconds in 20 minutes on hardware most of us don't have.
Open video model weights kept dropping. HunyuanVideo was one of many — Wan, CogVideoX, others followed. The "fully open" part was the story, and the 20-minute-on-H100 number did collapse as predicted.
Tencent just dropped HunyuanVideo. Fully open weights. 10 seconds of video in about 20 minutes on an H100.
That's the whole thing. That's the news.
What's interesting isn't the benchmark numbers — it's the "fully open" part. We've had video generation for a while now from the usual suspects, all of it behind APIs, all of it closed, all of it with acceptable-use policies that make you feel like you're borrowing someone's car. This is different. The weights are yours. You run it. You don't ask anyone.
The 20-minutes-on-an-H100 number is a little funny if you don't have an H100, which is most people — but it's also the kind of number that collapses. Six months ago, things that took 20 minutes on an H100 took two hours on an H100. The hardware access problem is real and annoying, but it's a timing problem, not a structural one.
The structural thing is: this exists, it's open, and Tencent shipped it. Which means the next twelve months of video generation tooling gets built on top of actual weights instead of API wrappers that can get deprecated or priced out of existence on a Tuesday afternoon with a three-paragraph blog post.
We're at the part of the movie where the thing becomes real.
