Open-Weight AI Rally Reshapes the Global Tech Race

A broad push for “open weights” in AI argues openness can sustain US leadership and blunt China, but serious tensions remain: Anthropic resists on security grounds, OpenAI and Google were slow to come aboard but joined, NVIDIA and Microsoft back openness, Meta and Alibaba mix open/closed approaches, and the US government signals support for openness. Frontier models remain largely closed for now, with distillation into open variants likely as the practical path forward — driven by cost, safety, and access considerations.
