In a 10-post thread, sebkrier and Jan Morgan argue that releasing flagship weights can indeed be optimal even for a profit-maximizing lab: commoditizing rivals, building developer ecosystems and trust, and using open release as the fastest distribution and branding lever for a challenger lab.
The thread lays out the economic case for why top Chinese labs keep giving away frontier weights.
