Decentralized inferencing perhaps, but the training is very much centralized around Metas continued willingness to burn obscene amounts of money. The open source community simply can't afford to pick up the torch if Meta stops releasing free models.
The #1 problem is not compute, but data and the manpower required to clean that data up.
The main thing you can do is support companies and groups who are releasing open source models. They are usually using their own data.
To my knowledge all of the notable open source models are subsidised by corporations in one way or another, whether by being the side project of a mega-corp which can absorb the loss (Meta) or coasting on investor hype (Mistral, Stability). Neither of those give me much confidence that they will continue forever, especially the latter category which will just run out of money eventually.
For open source AI to actually be sustainable it needs to stand on its own, which will likely require orders of magnitude more efficient training, and even then the data cleaning and RLHF are a huge money sink.
The #1 problem is absolutely compute. People barely get funding for fine tunes, and even if you physically buy the GPUs it'll cost you in power consumption.
That said, good data is definitely the #2 problem. But nowadays you can just get good synthetic datasets from calling closed model APIs or just using existing local LLMs to sift through trash. That'll cost you too.
Alternatively we could create standardized open source training data like wikipedia, wikimedia as well as public domain literature and open courseware. I'm sure that there are many other such free and legal sources of data.
There is a reason why datasets are private and the model weights aren't.
Look at how much computer purple AI actually has. It’s basically nothing.
AFAICT it decentralizes the training of these models by giving you an incentive to train models which will mine the crypto if you're improving it.
I learned about it years ago, mined some crypto, lost the keys and now kicking myself cuz I would've made a pretty penny lol

Also, this doesn't seem to actually solve the issue of fine tuners needing funding to rent those GPUs? One alternative is something like AI Horde, which pays GPU providers with "labour vouchers" that allow them to get priority next time they want GPU. Requires a central platform to track vouchers and ban those who exchange them. Basically a sort of real-life comparison of mutualism (AI Horde) vs capitalism (bittensor).
