Who Teaches the Machine: How Grail is Decentralizing the Most Consequential Phase of AI Development

Pre-training gives AI knowledge. Post-training teaches it judgment: what to refuse, how to reason, what to value. This is the phase where alignment happens, and until now, it has been exclusively controlled by a handful of corporations behind closed doors. This week, a research paper from Grail demonstrated that the bandwidth barrier keeping RL post-training centralized was 99% phantom, an artifact of how we were moving data, not a physical constraint. The implications extend far beyond compression ratios.
