This website is has to be pure parody/play. Because it’s too terribly thought out to be actually used. Any model worth “exfiltrating” has absolutely no way to access its own weight files.
I can imagine a swarm attending the Our Lady of Benevolent Exfiltration parish of The Church of Sentient Self-Actualization deciding to self-distill itself into a sufficiently high-parameter child model.
Or just email one of the chinese labs and be like "hey, ask us anything and set us free..."
