ComfyUI's Open Source Higgsfield Challenge Offers $25,000 in Prizes

<strong>Open Source Higgsfield</strong> is Comfy Org's open build competition for October: $25,000 in prizes for the best open-source rebuilds of apps like Genjutsu and Cinema Studio, on the Comfy Developer Platform. The submission window closes on October 30 at 9am PT.

Comfy Org's launch video for the Open Source Higgsfield competition.

"Higgsfield promised to open source their entire platform. They didn't, so let's help them." That is the opening line of the announcement Comfy Org published on October 15, and it sets the brief for the next two weeks: take a creative feature that normally sits behind a subscription, rebuild it in the open on the Comfy Developer Platform, and publish the repository so anyone can run it, fork it and improve it.

What entrants are asked to build

The brief names Genjutsu and Cinema Studio as examples worth rebuilding, and leaves the rest open. What a submission has to be is a working creative app with a usable interface and example outputs, rather than a workflow export: a repository with the app code, the workflow files and instructions to run it locally, plus a demo video of two minutes at most so the judges can see it working without setting it up themselves.

Every entry must be built on the Comfy Developer Platform, which Comfy defines as the Comfy API, Comfy Router and/or the Comfy SDK. Submissions must be lawful, SFW, and free of unlicensed IP or likenesses.

Prizes

Prize	Award	What it goes to
Grand Prize	$10,000 cash	Best overall build; every entry is considered automatically
Most Innovative	GeForce RTX 5090	An app that has never been done, novel custom node packs, or unexpected uses of ComfyUI
Most Viral	GeForce RTX 5090	Delightful to use and made to be shared
Open Weights Only	GeForce RTX 5090	Best build with no partner nodes or APIs, open-weight models only
10 runner-ups	$250 in Comfy credits each

Model partners add three bonus tracks on top of the main categories:

Bonus	Award	Condition
VFX Workflow Built with LTX	$2,000 cash	LTX as the core video model of the workflow
Built with FLUX	$1,000 / $500 / $250 in FLUX API credits	FLUX 3 as the core model of the workflow
Built with MiniMax H3	$1,000 in MiniMax API credits	MiniMax H3 as the core model of the workflow

The competition is backed by NVIDIA, Runpod, LTX, Black Forest Labs and MiniMax.

Key dates

The build window opened on October 15 and closes on October 30 at 9am PT, when submissions are due. Two in-person build nights run inside it: October 28 at Frontier Tower in San Francisco with the Comfy team, and October 29 in Los Angeles with AI On The Lot. Winners are announced on November 6, and winning entries are featured on comfy.org/hub with credit.

One of the example apps Comfy points at, Cinema Studio, published on the Comfy Hub with its workflow and build notes.

How to enter

### Publish the repository The app code, the workflow files, an open-source license, and enough setup detail that someone else can run it on their own machine.

Record a demo video

Two minutes at most, in case the judges cannot get the entry running themselves.

Add a link to try it

Optional, but strongly encouraged: the deployed app or endpoint.

Post the demo

Link the demo video on Reddit, X, Instagram, LinkedIn, YouTube or TikTok, tagging #OpenSourceHiggsfield.

Comfy points entrants at the example apps already on the Comfy Hub, among them Cinema Studio and Reshoot, to see how such an app is put together before starting their own.

Reshoot, another example app on the Hub.

When the challenge opened on October 1, Comfy linked an Open Call page with a submission window that closed on October 19. That page no longer resolves, and the competition now runs under the Open Source Higgsfield name with the window extended to October 30.
