We believe creative tools get better when they’re open. Comfy started as an open-source project, and millions of people use it for free because of that. So we’re putting real money behind the best open-source rebuilds of Genjutsu, Cinema Studio, or another creative app you imagine.
Build it. Publish the repo. Let anyone run it, fork it, and make it better.
Backed by Runpod, LTX, Black Forest Labs, and MiniMax.

Hey folks, I created this app for the ComfyUI Hackathon so you can create video Transitions/Sequences really easy now (R.I.P Higgsfield 🤣), can I request your Like/Star/Support please? https://x.com/jdnichollsc/status/2116164024039604618
The repo is MIT, totally yours <3
Glad I was part of this hackathon!
Does this mean the Higgsfield is closed and now the Higgs Bosun doesn't exist?
