Why Chinese Labs Embrace Open Weights: Is the Real Moat Data, Not Models?
caliberprot · reddit · 2026-09-28
A Reddit discussion on why Chinese AI labs are far more willing to release open-weight models while major US labs keep everything closed. The poster's theory: Chinese labs may not believe the weights themselves are the real moat in the AI race.
Alternative explanations raised: the actual moat might be specialized training data or evals — notably, some expert training data comes from US firms like Mercor and SurgeAI — or simply cultural differences. The thread weighs whether weights, data, or evals form the true competitive barrier.
