I don’t know of any super high-quality ones that run well, but the Open Assistant project, (now archived) collected responses from voluntary participants (myself included) to build what is now considered a very high-quality dataset of chat conversation pairs, truly open source, and all voluntarily submitted instead of scraped.
The models are reasonable for fine-tuning, but aren’t very good compared to newer models from large companies.
The fact that this man doesn’t understand that our entire system of checks and balances is what makes recommendations (and implements) drastic reforms, just shows how much of a fascist he is.
Adding Musk to his own special “task force” meant to “recommend” changes, which would, in reality, just be another avenue of control, is a clear attempt to centralize power.
