Open weights is becoming a license tier, priced by revenue

The license reads like a lease. Free for anybody under ten million dollars a year in revenue. Above that line, come see us about a paid agreement. And if you want to hand your fine-tune to somebody else, there may be a fee for that one too.

That is LTX-2.5, twenty-two billion parameters of video and audio, the weights sitting on Hugging Face this week where anyone with a login can pull them down. The file is open. The license still decides what you may do with it, and open weights is a different thing from open source. The gap between those two phrases is one paragraph in a lawyer's file, and this week that paragraph was the whole argument.

Here is what ComfyUI put on the table on October 15. A $10,000 grand prize. Three GeForce RTX 5090 cards, one each for Most Innovative, Most Viral, and a category called Open Weights Only. Ten runner-ups at $250 in Comfy credits. $2,000 cash from LTX if your VFX workflow runs on its model. $1,000 in FLUX API credits from Black Forest Labs. $1,000 in MiniMax H3 API credits. $25,000 all in, for the best open-source rebuilds of the apps Higgsfield sells. The post names its backers: Runpod, LTX, Black Forest Labs, MiniMax.

Read the category names. The house that started as an open-source project is paying real money for open source, and one of its three hardware prizes is reserved for open weights. The industry spent this year learning to sell the first while making the second.

The case for the open camp

I will build their argument better than they did, because it is a good one.

The files are real. LTX-2.5 is twenty-two billion parameters you can self-host on your own machine, and Lightricks pitches that as no per-generation billing, no per-seat lock-in and no forced API dependency. The company says most of the LoRAs trained on the previous version run on this one without changes, which is the kind of sentence a creator can use. The revenue line that scares people sits at ten million dollars a year, and most people reading this will never see that number from the wrong side of it.

The challenge is not a stunt. Somebody put up twenty-five grand and three video cards for repos that anyone can fork. MiniMax put its own API credits in the pot. Black Forest Labs did the same. A rebuild of a closed app, published open, is a thing a person can do this month, and ComfyUI is paying for it. That is what the open camp got right this week: real money for real files, and a floor under the license that most working creators never touch.

Then Friday, October 23.

Higgsfield, the closed company the challenge is aimed at, said Nvidia and TCV had invested as an extension to its August Series B, the round that brought in $400 million at a $5.4 billion valuation led by DST Global. Higgsfield did not say how large the extension was or what it was worth. It said registered users have passed forty million. Founder Alex Mashrabov said last month that the platform is on track to pass $1 billion in yearly revenue, which is the company's own claim.

Why the fight is over license terms

Hold both ends of that. Nvidia's cards are the trophy on the open-source challenge table, three of them, handed out for the best public rebuilds of a closed product. Nvidia's check is inside the closed product. The same name is on both sides of this fight in the same two weeks. Jensen Huang was in Astana for the announcement on Friday, and he told a fireside chat that "In just one year's time, it has improved tremendously," and that "it's not possible without agentic reasoning systems, and so the technology has become very useful in video generation." He meant it as praise for the tools. It reads just as well as a description of the settlement.

Higgsfield promised to open source its entire platform. That is the headline of ComfyUI's own post, and the words that follow it are "They didn't, so let's help them." The company that broke the promise is now backed by Nvidia and TCV, with forty million users and a billion-dollar claim, and the reward for rebuilding its best apps in public is a video card and some credits.

The open camp's own flagship this week is not open source either. LTX-2.5 is open weights behind a revenue line, with a paid agreement waiting above ten million dollars and a possible fee to move your fine-tune. LTX is one of the challenge's named backers, putting up a $2,000 bonus for open-source rebuilds. The category for the purest build in the contest is called Open Weights Only. The compromise has its own trophy now.

So look at what is being argued. Neither side is saying the weights should not be free. Both sides agree on free. They are arguing about the number where free stops. On one table it stops at ten million dollars a year. On the other it stops wherever a sales team says it stops. The phrase open weights used to be a promise about what you could build. This week it sat in a prize list next to the video cards, priced like everything else.

The lease still reads the same. Free under ten million dollars a year, a paid agreement above it, a fee to move your own work off the machine. ComfyUI is paying cash to prove the open camp can still ship, and Nvidia is collecting on the other side of the same two weeks. The number where free stops is ten million dollars a year. Above it, the weights cost whatever the seller says they cost, and that is true on both sides of this fight.
